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!

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:

Save Classic Cars
Armon is a car enthusiast passionate about keeping classic cars on the road. “Save Classic Cars” is a platform he created to share his love for vintage metal and foster the DIY spirit in others. You can catch his adventures on Instagram. Let’s hear from Armon himself about the rescue of this 1973 Datsun 240Z…
The Rescue
ARMON: “I actually remember looking into 240z’s when I was 16 years old- I’m 28 now. At the time, I wanted something classic that I could tinker with and drive throughout high school. Most of the Z cars listed for sale had some level of rust, which in hindsight, was nothing compared to what I would eventually get my hands on. I eventually gave up and ended up buying a classic mustang (then another, and other, etc). I still wanted a Z car, but didn’t actively search for one due to the price- the days of the “cheap” 240z were long gone in my book.”
“Last August (2021), I went on a walk in my neighborhood with my Dad. We spotted a Z car tucked away behind a pile of firewood just 800 feet from my house. I came back the next day and introduced myself to the neighbors- the gentleman who owned it bought it in 1989, paid someone to tune it (which made it run worse), and subsequently parked it in 1991. The car sat there for 30 years and became one with the earth- it had sunken into the ground, a tree had grown up next to the door, there was moss growing on the paint, rodents living/dying in it- the poor thing was a mess. The owner told me he wanted to sell it- I got excited and bought it on the spot (in hindsight, I probably should have at least opened the hood).”
Bodywork
“With the help of a few buddies and a truck, we dragged it out of the ground and down the street to my house. It turns out the person who did the tune up didn’t gap the points. It was running the next day, I actually drove it to the previous owner’s house the following week. The car ran incredibly well- someone had swapped in an L28, regeared it with 3.90’s and added the Mulholland suspension package.”
“Beyond that, it was an absolute mess. Floors, firewall, frame rail, floor supports, toe boards- all toast. It had been hit hard on the passenger side and poorly repaired. I fell in love with this car after driving it, I decided that I wanted to keep it and fix it. I stripped the car down to a shell, built a frame jig, and made the car whole again; literally. Oh, all of the metal work and mechanical restoration was done in THREE months. As fun as that was, I think I’m going to need a little break before I take on something like that again.”
Drivetrain and Chassis
“The cylinder head was rebuilt with a more aggressive cam and larger 280z valves, triple-Webers, and then completely resealed. Many Z enthusiasts mentioned adding a heat shield- I didn’t think much of it until I watched one of my Weber’s drool some gas onto the headers. A quick email to Z Car Garage and I was on my way home with a new heat shield! It looks great and keeps the Webers cool.”
Close-up view of the Z Car Garage Heat Shield beneath Armon’s triple-Weber induction setup, this unit is serial#00258:
With the engine taken care of, Armon added T3 front control arms, T/C rods and ST springs (courtesy of ZCG) along with replaced bushings throughout:
“I then sourced a 280z 5 speed and some Datsun comp style seats- my crusty (but solid!) go kart was ready to take on the world. Future plans? Continue flogging it! I’ve been driving my 240z every chance I get. I’d like to grab some stickier tires and hit some track days, it’s been an absolute blast to drive around town and in the mountains.”
Enjoying The Ride
We love that Armon drives his Z everywhere. He’s joined us on local events and gatherings like the Breakfast Club Rally. Their “Tokyo Calling 3” event (above) was ~300miles of fun through beautiful Sonoma backroads. (below) Meeting up with our client Dirk and his 1973 Datsun 240Z:
Armon followed through on his plan to track the Z, enjoying it an HPDE at Thunderhill Raceway. He also took the Z to an Autocross event at Sonoma Raceway.
Enjoy this video of Armon’s 240Z in action…
More photos of Armon enjoying the Z after rescuing it are in the gallery below…happy to see him at Nick’s birthday party:
Alexey Orlov captured the sound and experience of driving the Z in this video below:
It’Z a Small World
Z-car ownership often comes with some interesting stories from previous stewards. Armon was reunited with a former owner of his Z and it’s neat story:
ARMON:“That’s not just any 240z. That’s MY 240z! I recently met with the gentleman who owned my 240z from early 70’s to 1989- it turns out he lives half a mile away from me. He gave me the full story and sent me a few pictures from back in the day- it’s incredible. He [John] bought the car from the original owner not knowing of all of the hidden accident damage, then had a buddy weld it up (he never looked back, the car drove fine). Every few years, John would get bored, strip the car down to bare metal, and repaint it a different color in his parents garage. It’s been metallic brown (original color), red, yellow, green, black, and white- all with psychedelic 70’s stripes and graphics. He swapped in the L28 short block when the original L24 died and he would go to the legendary FAR Performance to buy his parts.”
“John was very excited to see his 240z in person after parting ways with it over 30 years ago. Every time he’d see something on the car, he would remember another story- it was incredible. The best part? He’s a Bay Area local and used to take this 240z up highway 9 and Alice’s regularly. It’s truly come full circle. This car is a textbook example of why classic cars are more than just…Cars! I’ve been an advocate for these things for a long time and I will never stop spewing my classic car propaganda. They bring people together, build communities, and remind us of good times. SAVE CLASSIC CARS and keep them on the road where they belong!”
Thank you for your support Armon we are happy to see our Z Car Garage Heat Shield on your S30. Long Live The Z!
