The Classic Sports Racing Group (CSRG) is excited to welcome Vintage Spec Miata (1990-1997) to all of their events! This is a fun, affordable way to get into vintage racing. If you have any questions regarding prep and presentation, reach out to Rob Fuller: rob@zcargarage.com. Please see below for more information and rules.
Why Vintage Spec Miata (VSM)?
Why VSM? It’s a great way to get into vintage racing at an affordable price point. The nice folks at the CSRG have a strict no-contact policy as part of their racing philosophy: this ensures the safest environment for you to race competitively while sharing the track with traditional cars.
Lastly, CSRG events are known for their camaraderie and undeniably cool eye-candy. If you want to mix it up with classic race cars of the 60s and 70s in your Spec Miata, this is the ticket.
Did we mention it is Fun! See what vintage racing with CSRG is all about in one of our race reports HERE!

The first race event is March 15!
Register your Vintage Spec Miata for CSRG’s first event, the 2024 David Love Races at Sonoma Raceway March 15-17. Registration details HERE. It will be a blast on Sonoma’s NEWLY PAVED surface with plenty of vintage cars and good times. See you there!
We love to see our parts installed and used on client’s cars. Race car driver and Datsun Historian Glenn Chiou is running our Z Car Garage CV Axles in this 1968 Datsun 510 U2.5L Trans-Am race car!
Glenn was preparing to debut his freshly restored 510 for the 2022 Velocity Invitational event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed the set himself with ease:
We also provided dyno tuning services to prepare him for the race weekend. The fresh Rebello L18 with Solex/Mikuni 44phh induction and BRE intake made great power.
Listen to this 510 make sweet L-Series music on our dyno in the video below. There is also race/paddock action with Glenn behind the wheel:
Privateer Spirit
We are happy to report that Glenn successfully raced at the Velocity Invitational event. It’s worth noting like privateers of the period, Glenn builds his race cars, maintains and manages racing efforts himself. Not an easy task so we applaud his passion and work ethic. Glenn builds some beautiful Datsuns and this historically-significant 510 is a shining example.

Glenn championed a vintage race group dedicated to the Historic B&C Sedan class and organized a “Celebration of the Two Five Challenge” display at the 2022 Velocity Invitational event. Two of the most iconic cars were present: the ex-Morton #46 BRE Datsun 510 (with Pete Brock below) and ex Kwech #3 Wetson’s Alfa. Yes that is Glenn with the legendary John Morton! Let’s take a look at the history behind Glenn’s Trans-Am 510 before we get into the restoration:
The Ex-Finn/Harris U2.5L Datsun 510
Glenn has a passion for re-telling the stories of legendary privateer Datsun racers and his penultimate restoration project was this 1968 Ex-Finn/Harris U2.5L Datsun 510, serial number PL510-023047. It is one of very few surviving cars that competed in the SCCA Trans-Am Two-Five Challenge, or more commonly known as the Under 2.5 Liter Series.
In 1972, Bob Finn acquired the car from a used car dealership in Santa Barbara, California. The car was sponsored by Bob Nolan Datsun and Chuck’s Shell Service in Santa Maria, California. Competition Street and Rally (CSR) Racing, a shop Finn ran out of Chuck’s Shell Service, prepared the car for competition. It is one of two cars in which an entire package of go-fast parts were purchased from Brock Racing Enterprises in El Segundo, California, as part of their “BRE kit car” program. Mac Tilton, then BRE Crew chief and engineer – later Tilton Engineering, developed the suspension and provided all machine work. Bob Finn and Ron Harris began racing #37 in late 1972.
Its first two races were the two final races of the 1972 SCCA Trans-Am Two-Five Challenge season at Laguna Seca and Riverside International Raceway, finishing 15th and 23rd. Unfortunately 1972 would see the end of the Trans Am Two-Five Challenge, but that would not stop Finn and Harris from continuing to race the car. They competed throughout the 1970’s in the SCCA B-Sedan class both regionally and nationally with numerous first place finishes, often beating out factory race teams. While Riverside International Raceway was its home race track, the car could also be seen racing at Willow Springs International Raceway, Laguna Seca Raceway, Sears Point, Portland International Paceway, Ontario Motor Speedway.
In that time, Finn and Harris competed against the likes of John Morton, Horst Kwech Harry Theodoracopoulos, Bobby Allison, Walt Mass, Dave Madison, Corky Bell, Norm Balzer, Pat Daily, and many other prominent racers. Bill and Jack Johnston acquired the car in 1979 and would go on to race the car for the next 33 years. Bill Johnston and Steve Dragus shared driving duties, while Jack was the crew chief. Dragus, who was best known for the building engines for Don “The Snake” Prudhomme, prepared the engines. Johnston and Dragus won three regional Cal Club Championships in the 1980’s, and would go on to win the last SCCA GT4 national race at Riverside Raceway before the track closed in 1989.

Restoration
The Ex-Finn/Harris Datsun 510 was not always in the orange livery shown above. When Glenn acquired the car several years ago it was red and he ran with this livery at many vintage racing events…until it was time to restore it back to its former glory…
Glenn is no stranger to vintage race car restoration. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this car himself and it is now back to the Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn also restored the Different Drummer Racing Z raced by Greg Sorrentino. This IMSA GTU Datsun 260Z features our Z Car Garage CV Axles and dyno tuning:
The 510 was dissembled for paint and bodywork, using period photos to guide the livery hand-applied by the talented Real Ralph:
As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces or use period-correct/surviving parts with archival guidance…shown below: vintage SW oil cooler, BRE remote oil adapter, expansion tank and BRE intake manifold:
Glenn assembled the interior with Mil-spec switches & motorsports grade wiring:
The fresh Rebello L18 is about to be installed…all done by Glenn himself in his home garage:
I was lucky to visit Glenn to see the restoration in-progress and it was simply a feast for the eyes…plated chassis parts, cool bits of history everywhere…plus the BADD 240Z nearby 🙂
Datsuns Are Driven!
With the restoration complete, Glenn has been enjoying the Ex-Finn/Harris U2.5L 510 at vintage racing events throughout the year. Follow his racing adventures on Instagram with more photos in the gallery below:

WE LOVE RACING! On March 3-5, Sportscar Vintage Racing Association (SVRA) hosted their SpeedTour season opener at Thunderhill Raceway. Z Car Garage had a great time racing and supporting several client’s Datsun 510 race cars running in B-Sedan Group. Enjoy our report with in-car footage and photos.
Z Car Garage Race Support Services
Z Car Garage offers full trackside support and in-house race car preparation so you can focus on driving. Our client Todd R is a great example of ZCG trackside support in action. He’s been racing his Datsun 510 privateer-style for the last few years and hired us for the first time last year, check out his experience HERE. For the SVRA event at Thunderhill we supported our clients Tom and Gabe:
“The weekend was a little bit of mixed bag. Friday went well with some stellar setup tuning to adjust to the RA1 tire (first time with them on track). Saturday was a bit of disappointment with fuel pressure issues, but Rob, Nick and Copper stayed focused and the smoking gun (Fuel cell foam was long past its prime). Problem resolved and Sunday was a success. Starting from the back of the grid (after DNF’ing the Saturday qualifying race) provided some passing fun, finished the race chasing Mark Nettesheim in his newly rebuilt Maroon ands Silver #37. We stayed nose to tail until he spun on T3 on the last lap, providing me a window to slip by. Great fun.”
Gabe’s B-Sedan 510:
Rob was in his Bay Area Datsun Dealers 510:
Rob’s race report:
“It’s been a few months since we’ve been in our B-Sedan vintage race cars. We headed up to Thunderhill Raceway for new event, SVRA’s first time hosting a season opener. Weather was spotty with fear of rain all weekend but the Datsun Gods blessed each session with a nice, dry track. Usual suspects Meghan, Corwins, Nick and Cooper all helped support our clients Tom and Gabe. So we were the trifecta of B-Sedan awesomeness in group 8.”
“Tom’s car fought us a bit but with help from Nick and Cooper we were able to get it back on the track for Tom to enjoy the rest of the weekend. We need more Alfas and 2002s out there…we are the huge 510s fan and biggest advocate for rhem but it would be cool to see a wide of variety of cars racing. I was able to win one of the races and Gabe was in the front of the field. Really proud of him going from mid-pack to top 5 racers. He will only get faster.”

A weekend of great racing and good times
Special thanks to ZCG crew Nick and Cooper for kicking ass all weekend to ensure our cars were safe and running in top form. We had a great time and it was nice to see new faces and old friends like David Carroll. He won OPTIMA’s Search for the Ultimate Street Car in his LS-powered Z!

We love motorsport and it is our pleasure to bring more enthusiasts into the world of vintage racing. Z Car Garage offers full trackside support and race car-preparation so you can focus on driving. Our client Todd R is a great example of ZCG trackside support in action. He’s been racing his Datsun 510 privateer-style for the last few years and hired us for the first time at the Laps For Laguna event back in May.
Z Car Garage had a blast racing and supporting Datsun 510 race cars running in B-Sedan Group 9 (John Morton Cup). We were super proud of Todd: he was able to concentrate on his driving, achieving his highest placing (p6) and personal best lap (1:48.3) time. You can see our full report from this HERE, and let’s take closer look at Todd’s experience with Z Car Garage trackside services.
Race Prep for Todd
Todd had us prepare his B-Sedan 510 prior to the Laps for Laguna event with standard track-event services including dyno tuning and alignment. He also purchased a set of 13×7 Panasport Wheels from ZCG. We are proud to offer 13×7 Panasport racing wheels in perfect fitment for your B-Sedan/TransAm series Datsun 510 running vintage-class spec 205/60/13 Hoosier R7 (and other) tires:
The welded diff was replaced with OS Giken limited-slip (4.38) unit. Diff services are performed in-house at ZCG:
We changed the ignition, spark plugs and dyno tuned the L-Series engine for 110 race fuel.
Enjoy this video the dyno tuning sessions at Z Car Garage and in-car race footage from Todd, volume up!
510 Beginnings
Let’s take a look at how Todd got into 510s…
“My history with the 510 begins in my childhood. We had a 4 Door 510 as a family vehicle and went everywhere in it. I have many memories of tinkering on cars with my dad in the garage. My first car at 15 yo was a Datsun 1200 I bought with my twin brother for $200. Engine was dismantled and all parts in a box under the hood sitting on the engine block. We put it back together w/Dad at night after he got home from work using the Haynes manual. My first car I bought myself in 1988 out of the classifieds was a 1972 Datsun 510, Lowered, L18 and a webber carb, 5 speed painted white. Great car, went everywhere especially to the Santa Cruz Beach. I lived in Livermore at the time. Sadly it got smashed into in front of my parents house and that was the death of it.”
“I received my racing license in 2015 in a rented 510 from Larry Oka (The One and Only)( nicknamed the THRASHER) I subsequently bought that car to continue racing for 2015 and 2016 in SCCA ITC SFR region racing at Laguna, Sonoma and Thunderhill. I became the 2015 San Francisco Region Champion in ITC for SCCA that year. At the end on 2016 I was handed an opportunity to purchase a Vintage racing ready 1971 Datsun 510 again thanks to Larry Oka. I made the deal and started racing with CSRG in Vintage sedan racing. This was where my heart was. I had been attending Monterey historics for 30 years and finally was going to be a Vintage racer. I raced and learned with that car but it needed to be better prepped for vintage, its livery was a bit contemporary and the car was Street/ITC built.”
“I had the car painted to its current day Black over White #88. I wanted to make it my own. I modeled it after the F.A.R Performance Datsun 1200 Livery of the early 70s to pay homage to the bay area Datsun performance shop in the 70s and 80s. The ZCG of its day. They had a successful racing history with Roadsters, 1200s, 510s and Z cars. I then brought the car to Troy Ermish who performed all the proper B Sedan Upgrades at his shop over the course of a few months. As more 510s started showing up in Vintage racing…Like Troy, I was left in the back. I knuckled down and raced as hard as I could. I reminded my self of a saying by the great Paul Newman..”Its more fun to make a slow car go fast than a fast car go slow”. The prize at the end of the day in Vintage racing is returning home ALL in one piece. I sourced a Rebello L1800 and installed it, and was able to race two races in 2021 after install at Sonoma and Thunderhill.”
“As for Rob…We met at racing school in 2016 when he attended and I was working for Larry Oka racing for the weekend. He had that contagious energy of course and that’s where I learned of Z Car garage. As a Datsun owner racer I knew I I would need his services in the future, and of course we ended up racing together on a regular basis with CSRG. We would always be staged together in the Paddocks since all the 510s typically parked together.”
“I have always been a Do it yourself’er and was able to take care of all my needs up to this point, but at that Sonoma race in 2021 I had issues. I sorted out some problems but had a persistent misfire. Thankfully Magic Hands Joshua Corwin of ZCG was providing Track Support to Rob and others that day and my problems caught his interest because he’s a fixer. Rob had allowed him to step away for a moment and he was able to determine my ignition plate in the distributor was loose and causing a misfire. They also supplied me with a Coil and plugs as part of the fix. Without Z Car my weekend would have been over if not for them. THIS WAS MY AH HA moment. With Rob’s thorough knowledge Datsuns and racing and the skills of his guys, Thats a win.”
Success at Laguna Seca with ZCG Race Support
Todd’s experience with us at the Laps for Laguna race event was so good we had to share it with our readers and anyone looking to join the fun…
“My first race this year was in May at Laguna Seca. I hadn’t had my car out of storage all winter and because of a crazy busy work schedule I couldn’t do my own prep and services prior to racing. I got my car into Z Car Garage and they more than dialed it in in just a few days. Nut and Bolt check, Dyno tune, alignment, scales. My car had never been better. I also enjoyed track side support that day at Laguna. I had to worry about NOTHING when parked under that ZCG EZ up. It was a difficult adjustment and I didn’t know what to do with myself. Rob told me to worry only about me, the car is covered. That security knowing Z Car was on the job simply made me faster, finally everything was dialed.”
“First session I finished 14th, second timed session I finished 10th and For the First Time ever, Sunday afternoon race I finished 6th overall in group 9 B Sedan group. This was possible because ZCG had me covered, the car ran and preformed better than it ever had. I was more relaxed going onto each race, AND iIdiscussed every session with Rob to preform better for the next race to come. Simply the best. I would recommend Z Car Garage Track Support to everyone.”
Thanks for trusting us with your race preparation Todd. We are very proud of you and happy to have you part of our group!
