Classic Sports Racing Group (CSRG) is hosting a pre-season tech day for anyone who wants to have their car inspected before the first event of the season, March 15 at Sonoma Raceway. This year there are three great locations for your geographical convenience: North Bay, Peninsula, and South Bay! All three locations will be hosting the tech day on Friday February 23rd. Please call or email the location you’re planing to visit to confirm their hours and to let them know you’re coming. Thank you to all three businesses for taking time out of their day to do these tech inspections. We look forward to seeing you all at the track in just under a month!
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!

Happy Birthday to Joel Anderson who passed away in 2021. Joel would have been 82 years old today and we miss him dearly. He was an immensely talented graphic artist and successful privateer Datsun racer with regional and national championships all over California. See Joel’s racing career and learn how he helped us enter the world of vintage racing in our tribute HERE
An amaZingly talented driver, Morton brought Brock Racing Enterprises (BRE) four National SCCA Championships from 1970-1972: two C-production championships in the Datsun 240Z and two Trans-Am championships in the Datsun 510. Enjoy our photos with John Morton over the years and let’s all wish him the best birthday!

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:
