We love to see our parts installed and used on client’s cars. Race car driver and Datsun enthusiast Brad H is running our ZCG CV Axles in this IMSA GTU 240z race car!

Brad is preparing his Z for the next race season and a half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. He installed set #312 with ease, stock half shafts (left) and ZCG CV Axles (right):

“The rear end is a LSD R200 with a 3.70 gear. I’m not really sensitive to the rear gear ratio because of all of the variability I have in the gear box. It’s connected to the rear hubs by Z Car Garage CV axles. I had been looking for options on axles simply because the thought of going into Nascar 4 at Daytona with 50 year old U-Joint technology made me nervous. I heard about Z Car Garage from Randy Jaffe. We are both in Atlanta and I was at his shop one day because he was kind enough to let me borrow a rear diff to carry as a backup to Daytona. While there, he showed me the CV axles and I reached out to Rob to order a set the next day. We have kept a great relationship ever since.”

Brad’s IMSA 240Z Build

Let’s hear how Brad found and built his 240Z race car:

“The story of my car starts with a poster I had on my wall as a kid of the Bob Sharp Racing GTU Z that was campaigned in 1976. We raced ITS Z cars back in the late 80’s, but I had always said that if the situation presented itself, I would build a tribute to that car. The original was destroyed in ’76 at the Camel GT at Road Atlanta when Sharp blew a tire coming up to the bridge and hit the embankment hard on drivers left. That left a tribute as the only option.”

Brad found a solid chassis that was running as a track day car in Ontario Canada. Peter Skillins had built the car (www.datsunzcars.com) and had done a fantastic job. The cage was done by Blaise Csida (www.bcracecars.com) who is a well respected Trans Am driver/car builder. In addition to a very robust cage, several additional reinforcements were installed like additional shock tower structures and additional stiffening structures on the front frame rails.

“The car was then sent to Burtin Racing (www.burtinracing.com) here in Atlanta for final assembly and installation of the IMSA GTU body kit that John Washington at ZTrix puts together. It’s a great kit that requires minimal modification to the body panels themselves, but the fabricators at Burtin when a bit further by putting together some additional components to support the kit under my application. Specifically was a new nose frame and airbox set up as well as new customer rear fender inner liners. All body panels are removable with 1/4 turn fasteners and the car can be stripped in less than 3 minutes. The Burtin fabricators (Terry and Damon) work daily preparing/maintaining a top tier Trans Am team (Tomy Drissi and Simon Gregg), the work they do is top notch and highly recommended. All along the way the fabricators at Burtin Racing made small suggestions on performance and safety ideas.”

The motor was built by Steve Nelson at Top End Performance in CA (www.racetep.com). It’s an L28 with a 2MM stroke add that runs at 13.1:1 compression.

“It has a race cam and is fed by 3 Mikuni 44PHHs. Steve and team do a great job on the bottom end, but the reason I went with TEP was that they use Slover head porting. Slover has long been one of the best head preparers in the L series motors going back to the origins of L series racing engines. If you’ve ever seen the work they do you would quickly understand why. Steve also recommended running the Electromotive crankfire ignition system. I was hesitant at first, but was sold very quickly when you get to see ease of timing adjustments and the complete elimination of timing slop you get at over 6-7,000 RPM. That was a great call.”

“The gearbox is a Hewland STA wide the came out of one of Burtin Racing’s TA cars. They upgraded to sequential, so Claudio (the team owner and good friend) recommended we install the Hewland behind the L28 because of its reliability and optionality with gear sets. To do so required a custom adapter that the Burtin guys made on the CAD and removal of the existing tunnel. We went with a Quartermaster dual clutch set up that connected to the 28 spline shaft of the Hewland. With this box installed, I have access to no less than 50 gear sets which lets us gear the car for each track we go to. For Road Atlanta, which is my local track, we run a 2.20/1.88/1.44/1.23/1.09 configuration with a 1:1 spur gear.”

Brad enlisted Andrew at Wheelflip (www.wheelflip.com) who was able to find him 2 matching sets of late 70’s BBS centers with the stock 4X114 bolt patter. After taking many measurements they ended up with 2 sets of gold 16X11 fronts (5.5 outers/5.5 inners) and 16X12 rears (6.5 outers/5.5 inners). Brad runs Goodyear Eagle slicks with the 430 compound:

“The car was fully wrapped in the Bob Sharp Racing livery from 1976 by the same folks that wrap the Burtin Racing TA cars, AAA SignCrafters (www.aaasigncrafters.com). Huge thanks to the folks at Harris Decal (www.harrisdecals.com) for putting together all the special decals that were required to get the look correct”

In mid 2021, Brad moved to his own shop in Buford, GA under the operation of BPH Motorcars, LLC. The car is currently maintained by Jason Howe of Howe Custom Fabrication. Jason was a former fabricator at Burtin Racing as well as for the Panoz racing operation and does fantastic custom work. You can follow Brad’s racing efforts on Instagram.

Thanks for your support Brad! We look forward to seeing you on the track for the 2022 race season, LONG LIVE THE Z!
