All of these parts were developed on Mrs. Butters to offer our clients a balanced performance package. Enjoy the article with photos and interview with Rob Fuller by photographer Naveed Yousufzai HERE.
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.

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!

Our ZCG Big Brakes have been winning over Z-car enthusiasts locally and globally. Jaime recently purchased a set and performed the installation himself in his garage in Los Angeles, 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. Let’s take a closer look at Jaime’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:
If you follow Jaime on his Instagram page its clear that his attention to detail is impressive. He successfully installed the BBK on his Z, complete with functioning parking brake:
Front and rear:
Easy fitment behind his 15×8 Watanabe (zero offset) 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. Jaime was very happy as well with great feedback:
“The brakes are a complete game changer. Money well spent”
A Beautiful Work In Progress
This is Jaime’s first vintage car to work on and his goal is to have a reliable daily driver/occasional track machine. Under the hood is a ported/polished L24 with Spirit Garage R header, triple-Weber carbs tuned by Kyushahousetaka, Fujitsubo Leagalis R exhaust and our very own ZCG Heat Shield.
He’s been Enjoying The Ride (and braking with no worries)
The chassis was treated to a full coil-over suspension and many more parts from Techno Toy Tuning
We really like Jaime’s aesthetic with the 904 Kilamanjaro white against the gunmetal Watanabe wheels, JDM tails, 432 grill, xenon bumper w/Skillard lip and JDM fender mirrors:
He also installed a Vintage Dashes unit and reupholstered the seats:
Keep up the good work Jaime and we are very proud to have our Big-Brakes on your Z!
Stay tuned for more customer installations of our ZCG Big-Brakes! Check out our ZCG CV axles HERE.
Long Live The Z!

On Saturday I joined six other cars for a morning cruise through the Santa Cruz Mountains. The two S30 Z cars with us were running our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!
Glenn’s 1972 Nissan Fairlady 240z-L
Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:
“The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me and the ZCG brakes deliver. WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car”
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 pictures of the Big-Brakes being installed on Glenn’s Z:
Glenn was having fun on the twistys on our cruise (see video below). Learn more about his Z in this Petrolicious video.
James’ 1972 Datsun 240z
James is running our ZCG BBK (1st gen, 328mm) and Z Car Garage CV Axles in his turbocharged L-Series beast:
You can learn more about this 560whp Z on Speedhunters and see it in action on Hoonigan Autofocus. James also had a blast on our Saturday cruise:
Saturday Cruising
We started our drive in Downtown Saratoga and made it to the coast via Bear Creek and Bonny Doon Rd. Here is a short video:
We were happy to enjoy the company of cool cars and cool folks, also joining us:
Dustin’s 510
We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. The side exit exhaust is loud!
Tony’s Mazda RX-2
Tony has had this RX-2 for many years. In addition to the full restoration it now has a full (S5) 13B drivetrain with a Ford 9″ rear end! It is mint. I haven’t seen Tony in many years so it was a joy to have him along:
Lloyd’s AE86
Lloyd has a very cool collection of cars and this AE86 is the latest. Although it sports an F20C drivetrain (Lloyd promised me it’s not the same car as this one), it has numerous upgrades for a better drive. Gotta love TE37s:
Geoff’s BMW 2002
Geoff’s no stranger to our Bay Area cruises and also owns a Lotus 7. He was the only German this time with his BMW 2002 on rare Campagnolo wheels:
I drove my SR-powered ‘67.5 Datsun Roadster and it was a great way to spend the morning.
Yes, that’s a Ferrari 250 GT Lusso flying by on HWY 1!
