Our ZCG Big Brakes have been winning over Z-car enthusiasts locally and globally. Jeremy G recently purchased a set for his 1973 Datsun 240Z and performed the installation himself at his shop in San Jose, CA.
Big-Brake Kits Available For DIY Install!
Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Enjoy these pictures of Jeremy’s beautiful S30 and his ZCG Big-Brake installation:
As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake:
Jeremy successfully installed the BBK on his Z, complete with functioning parking brake:
The brakes fit behind his 15×9(F) and 15×10 (R) Longchamp XR-4 wheels:
Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. Jeremy was very happy as well with great feedback:
“Big thanks to Rob Fuller and the guys at Z Car Garage for working with Stoptech to make this awesome big brake kit for S30s. Installed yesterday and spent most of today running around and they feel great. Best feeling and balanced brakes I’ve ever had on any Z.”
Jeremy removed and sold his existing Wilwood setup, not uncommon once you experience just how good our Big-Brakes are!
A 3.5L Driver
The best part is that you can see Jeremy frequently Enjoying The Ride all over the Bay Area. This Z gets driven! Under the hood is a Rebello 3.5L soon to be fed by 50mm Mikuni carbs tuned by Kyushahousetaka. We dyno tuned the Z last year with 44s and this G-nosed beauty baselined at 238hp/229tq. With Rob’s tuning the Z produced 288hp/257tq to the wheels! We are really excited to unlock more power with a few upgrades, now that Jeremy has brakes up to the task!
More pictures in the gallery:
You can see even more pictures of the Z on Speedhunters HERE. Looking forward to more tuning sessions and thanks for your support Jeremy!

Long Live The Z!
It takes teamwork to make the Dream work. We want to thank Love20bee for sourcing and re-finishing these SSR Watanabe RS8 wheels for James’ 1972 Datsun 240z.
It has been said that “wheels make the car”. Matt and his team nailed it with these RS8s sized 10.5 (F) and 12.5 (R) on massive 275/315 width Nitto NT-01 tires.
While they look killer standing still, they are even sweeter in motion as seen in the video below:
Rob and owner James are proudly wearing Love20bee hoodies. We highly recommend Love20bee for your wheel needs. Check them out on Instagram and Hoonigan Autofocus.
We met Ken W last summer when he stopped by Z Car Garage to meet Rob and have his S30 inspected. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with upgraded suspension parts and a Rebello 3L engine transformed his 1971 240Z into a fantastic sports car.
The Right Z
Before we dive in to the upgrades let’s take a look at how Ken got into Z cars and finally found the right one…
“When I was a junior in High School, the cool kids were driving Mustangs, Camaros, and ‘Cudas. Always different, my imagination was captured by the ’71 Datsun 240z. Being a Kansas farm boy on the lower end of the economic scale, had to settle for a ’64 Ford Fairlane 500 4-door with the 269 V-8. Knew that someday I’d own a 240z. Spent 2018 researching the 240z market. In January 2019, bought a red ’72 240z with Wilwood brakes, QA1 coil-over suspension, 17” wheels. A little rough but convinced me that owning a 240z as a daily driver, was going to make me happy.”
We inspected Ken’s red ’72 240z and found many problems. Rob suggested finding a chassis in better shape to make his own. After our evaluation Ken consulted with fellow S30 owner/racer Glenn C to affirm that ZCG was the right place to be. Ken was convinced that the S30 is a great rally car and began searching again, finding this green ’71 on Craigslist, near Sacramento.
“Rob gave this car his approval as a basis for the rally car that I wanted to build. ZCG is so popular that we weren’t able to get it in for the chassis upgrades before the Mother Lode 400 rally in June 2019 . The car was fine, but only fine. Yes, the brakes and suspension worked and the motor was dependable, but with the enthusiastic style of rally driving, showed they really weren’t up to the task.”
ZCG Big-Brakes and CV Axles
The upgrade process began, giving Ken the ability to brake on a dime, perform well and daily drive. We handed him the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂
As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel and retaining factory emergency brake lever! A few details below:
Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)
Rotors: 280mm x 20.6 with Alum 7075 hats
Pads: Stoptech 309 sport street pads
Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.
A few closer detail shots of the calipers, rotors and hardware:
We removed Ken’s brakes and installed our ZCG Big-Brake kit. The Z also received Tokico 5-way struts with Eibach springs and suspension parts from Techno Toy Tuning. New parts included adjustable T/C rods, rear control arms, new bushings, rack bushings, steering coupler, factory Nissan ball joints, new wheel bearings and more. We really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.
ZCG Big-brakes up front:
T3 T/C rods and new brake master cylinder/booster:
Suspension Techniques sway bars installed front and rear:
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality retained! Ken was pleased with the brakes:
“I really the brakes. Having experienced stock brakes and the Wilwood’s (Stage 4 front and rear), was really interested to discover if the ZCG Big Brake kit was all that I’d heard about. I’m here to say that the Big Brake kit exceeded all expectations. Under hard braking, feels like I’ve just driven into a huge pool of thick super glue or that someone immediately behind me has just switched on a huge electromagnet. Undeniably shorter braking distances. Huge confidence when diving deep into corners.”
Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. Ken’s Z received set #298. We have over 100 CV axle kits on customer cars and we are stoked with all of the positive feedback.
Stock half shafts and control arms (L):
Before/After suspension upgrades. Not shown is the ZCG exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip:
Great feedback again from Ken regarding the suspension upgrades:
“In August 2019 it went into ZCG shop for the upgrades. Let’s talk about the suspension first. My red ’72 had QA1 coil-overs and it wasn’t particularly balanced or optimized. Too soft in front, too harsh in back, little squirrely under brake or gas. By comparison the ZCG components showed care in selection, thought in design and clear goals in creation of a balanced package. The car is impressive under braking, squatting uniformly and smoothly. Under hard acceleration, it tracks straight. The CV axles are works of art and well suited to handle the Rebello motor to come.”
More Power
With braking and suspension sorted all Ken needed was power to match. Without going too wild we opted for a Rebello 3L, retaining SU induction. The 3L still leaves room for aggressive cam/Mikuni induction upgrades should he feel the need. A few pictures of the fresh motor, more in the gallery below:
Ken enjoys tinkering with vintage motorcycles and rallying. While running the Snowball Rally the car did really well and he had a great time but unfortunately, it was hit by a motorist (not part of the rally). We called upon our man William from William’s Auto Body to fix everything and re-spray.
While the motor was out, we cleaned up the engine bay. Everything came out, the bay was painted, new seals around all hoses going through the firewall. The engine got an MSA 6 to 1 header, all intake/exhaust gaskets, MSD6Al box with tach adapter, Koyo race radiator, zinc’d hardware and new alternator/starter. We ensured that he would be able to rally wherever and whenever.
Backing the 3L is a 5-speed with JWT aluminum flywheel and Exedy clutch:
Rob dyno-tuned the Z with the stock L24 (109hp/128tq) and the 3L, now making 199hp/209tq to the wheels:
Enjoy the L-Series music!
Panasport Wheels
What is the perfect companion for Ken’s Z, now that it has full suspension and wicked brakes and fresh paint? Panasport wheels! We replaced the old-school slotted wheels with 16×7 Panasports and Bridgestone’s killer S-007a tire in 225/50/16.
“The Wilwood Stage 4 front brakes required a spacer to move the generic Japanese front wheels out far enough to avoid fouling the calipers. This meant running 215/45/17 tires. A drawback to the 17” wheels is that the space-saving spare can’t exceed 16” in the spare tire well. I totally love the beautiful Panasport wheels! When I take the car to Z car meet-ups, everyone says “this car has been to ZCG, right?” The wheel and brake combo means I gained 10mm tire width and no spacers. We agreed that for rally purposes, I’d change the tires every 3 years, so Rob picked out some nice sticky ones.”
Rallye On!
Ken was smiling ear to ear and told us we built him a Z car he really enjoyed:
“The results are fabulous! My car is such a hoot to drive. Quick off the line, easy to spin the tires. Now I understand why Rob recommended the CV shafts. The car was awesome on the 2019 California Melee. Had so much fun driving the rally with my brother who flew in from Kansas. He drove it much slower than I did, so when I took my first shift, diving it deeper and deeper into the corners, accelerating harder and harder out of the corners, that I proposed establishing a safe word if he wanted me to ease off the fun.”
We have been checking in with Ken and he’s happily Enjoying The Ride. We even spotted his Z cars while cruising through the neighborhood.
“I’m so happy to have met Rob and provided him with a car that has ‘good bones’. Enjoyed working with ZCG. A key for me is that ZCG has been able to provide all the upgrades, in an integrated package. Didn’t want to use multiple shops and fight through finger pointing. Trust Rob and his crew, they’ve done these upgrades 100 times or more. They know what works and what doesn’t. Personally, I care more about the quality of work performed and the result, rather than shopping for the lowest price.”
Thank you Ken for allowing us to help you achieve your vision of the ultimate Z car. We loved working with you. Long Live The Z!
The Z Owners of Northern California (ZONC) is one of the oldest Z car clubs in the nation. We are proud to be a part of this group and support its members, like former ZONC president Ken C. Ken brought his 1970 S30 to Z Car Garage for a dyno tune and minor sorting. In true do-it-yourself fashion Ken performs most of the work himself, even installing a set of our Z Car Garage CV Axles in his garage.
“When I was 19 and in the Air Force I saved up for a Pinto, saved more for a Maverick…then I saw a 240z. I always wanted a 1970 and got this one in 1985. I drove it everywhere including Maine. I do 99% of the work myself with lots of details/upgrades like a huge cooling system (custom shroud) to support the A/C, rebuilt steering rack and all lightning.”
We recall seeing Ken’s Series 1 240z at the ZONC Annual Car Show in Brisbane, CA where he picked up an award for his efforts:
You can imagine how honored we were to have Ken let us work on his Z that only he’s allowed to work on. He had built a Rebello 3L with 5-speed/stock clutch and wanted us to do final sorting:
“Rob has always supported ZONC, done good work for its members so I trusted him to help get my Z in shape. It was running too rich, stumbling and it would die when A/C was turned on.”
Rob dyno tuned the L-series with SUs gaining more hp/tq and eliminating the hesitation Ken reported. The dyno plot shows his old L24 from a ZONC dyno day at the shop vs the current Rebello 3L now making a stout 183hp/191tq at the wheels. Enjoy this dyno video with sweet L-series music:
ZCG CV Axles
Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 100 sets of axles, with customers installing and enjoying them on everything from street cars to full-blown IMSA racers. These CV axles will help transmit power to the ground and ensure smoother operation compared to your standard half shafts. Full details can be found HERE
Ken had purchased a set of our ZCG CV Axles and installed them himself.We love to hear from customers that are using our products and he reports that the axles were easy to install and well-engineered. Thanks Ken, and nice work:
“The ZCG CV axles—much smoother happy with less vibrations, best CV axles I’ve ever seen. It took me about 90 minutes to install. Super simple and easy and Rob is of course always supporting his own products with great service.”
Please contact the shop or visit our website to order your CV Axles!
Time To Enjoy The Ride
Ken continues to enjoy driving his Z, to shows or cruises and around town:
More inspiration for the Do-it-yourself’er…Ken is also restoring this ’72 S30 back to its stock blue/white in his garage (and kitchen)!
Thank you Ken for entrusting your Z to us. Ken is an avid baker and makes his own jerky, we also thank him for the cookies (which he’s known for) and snacks he provided to the ZCG crew. LONG LIVE THE Z!
Yoni has been our customer since 2014 and after having a taste of vintage Z cars at the shop he finally found one to call his own. This green S30 has had a long history with ZCG and before Yoni picked it up he requested intallation of our Z Car Garage Big-Brakes and Z Car Garage CV Axles to make it perfect.
This Z was previously owned by our customer Alan L who purchased it in Idaho in 1995. We worked on this car since the late 90’s and it has many neat parts suiting his taste like a nasty 3L mated to a 4-speed transmission, stock brakes with race pads, Panasports and roll bar. He drove the wheels off this thing not only on the street but at the track too. In 2013 Alan retired to Palm springs and decided it was time to sell, sending it to us to find the Z a new home.
We got it here and installed a Rebello 2.9 with SUs, early 5-speed trans and some cleanup work.
Timing worked out wonderfully as Yoni was jonesing for an S30:
“I got my G37 in 2013 as a gift to myself for graduating college and landing my first “big boy” job. I researched the best garages in the Bay Area and only one stood out: Z Car Garage. I sent my first email to Rob in 2014, and my journey with ZCG has continued since then. Over the years I’ve only brought my G to Rob and his amazing team. They’ve performed all my routine maintenance and a couple major repairs and realized I appreciated the car as it is. It fulfilled it’s purpose for me – a fun, fast, reliable daily driver…
… Around 2019 I considered selling my G. There was nothing wrong with it, but I felt like something was missing for me. At this point I had spent the majority of my career developing electric vehicle technology (and even an electric flying taxi!). Spending so much time thinking about what was coming next made me, ironically, want to drive something more physical. I wanted to be able to experience driving something with personality, something that required actual skill and gave real feedback. I wanted something more rewarding…”
The Butters Effect
After a routine visit to ZCG and seeing all the vintage Z cars, Yoni took our shop demo car “Mrs. Butters” for a spin. It solidified his need for a Z:
“Rob eventually he let me drive one of his personal cars, Butters. The thing about driving Butters for the first time, especially if you’ve never driven a Z car, is that it’s totally unfair. Butters is kind of like the best version of what a Z car should be. It’s not another LS swap, not a restored garage queen, just a solid Z with a big engine and killer brakes. Butters is like the gateway drug of Z cars – you leave expecting all Z cars to be like that.”
Fast forward a few months and Yoni was ready to purchase the green Z. The 3.1L was already transplanted into customer Jason’s ProjectZ and the freshly built 2.9L with SUs and early 5-speed took its place:
Rob dyno tuned the L-series, now making 175hp/190tq at the wheels:
Enjoy the video with sweet L-series music!
The Z was good, but not “ZCG-good”, so we fixed that. Before it went home he had us install our ZCG Big-Brakes, ZCG CV Axles, new Bridgestone S007a tires and more:
“When Rob showed me the car for the first time, I was mostly sold. The car was great, but the stock brakes needed to go (thanks to Butters). The car had a huge binder of records and history that went along with it. The price was right and we agreed that Rob would install ZCG big brakes, CV axles, and some sticky tires before I took delivery. He also took care of a few small items I wanted.”
ZCG Big-Brakes and CV Axles
We handed Yoni the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:
As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever!

A few closer detail shots of the calipers, rotors and hardware:
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!
Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 90 CV axle kits on customer cars and we are stoked with all of the positive feedback.
Yon has CV Axle set #331. Stock half shafts (L) and ZCG units:

A few more items were sorted including bumper over-rider removals, corrected side markers and replaced antenna
Welcome to the Z car family!
Yoni and his super supportive wife picked up car and they were stoked. Now he has a rad vintage 240z to go along with his daily G37 coupe.
“I’m really happy with the car. It’s the perfect compliment to my G, which I am definitely keeping now. It’s also really the best mix of things I wanted in a first Z. A good engine, moderate suspension upgrades, awesome brakes, and nice but not perfect paint. It’s something I can really enjoy driving and sharing with people without being paranoid about keeping it perfect.At some point I’ll be back to have Rob work on the interior with me. Who knows, maybe there’s a set of triple Mikuni carbs in my future. For now though, I’m enjoying the ride.”
Thank you for your continued support an we love working with you Yoni. We are glad that you are now a 240z owner, welcome to the family and LONG LIVE THE Z!
