Classic Sports Racing Group (CSRG) hosted the Sears Point Challenge at Sonoma 10/3 and Finale event at Thunderhill 11/1.  Z Car Garage participated  in both events, supporting several client’s Datsun 510 race cars running in B-Sedan Group. Great weekends filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our race reports with photos and video!

 

Sears Point Challenge 10/3-5

 

ROB: Beautiful weekend at historic Sonoma Raceway (which will always be Sears Point to me). We had a a few bitchin’ 510s including Tom Dockery and Kenny. Super excited to test out the suspension fresh and adjustments on Noah’s Bluebird coupe.

 

Everything seem to be working well with Tom, Kenny everyone up to a really good pace, it was fun.

 

Lots of cool hardware in the paddock:

Vintage Spec Miata

 

ROB: 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. Each event we see more really clean VSPs coming out to race. Season high for us in Sonoma, with I believe 10+ cars out there:

 

Speaking of glorious…we would like to introduce you to “Little Butters”, our 1991 Vintage Spec Miata that will be available for rental throughout the vintage race season. Contact Rob at ZCG for details. Since this is a new build for I drove it for the weekend to make sure it was sorted and ready to rock for any client that wants to enjoy it. It has a competitive race engine, Penske shocks which are the current suspension for SCCA Spec-Miatas. Just to pay tribute to how wonderful Mrs. Butters Z (our Series 1 shop 240z) is,  we painted it Safari Gold. It’s nickname is Little Butters,  Josh likes to call it “I can’t believe it’s not Butters” and then we picked the number 23 because we are Nissan dorks.

 

Anyway it was fantastic to have the car out and then honorable mentions are Lora B, she keeps kicking ass in her Spec Miata and Allison as well. Also on Saturday and Sunday we had Ross Lindell in the Randy Pobst National Championship-winning Miata (1992)…pretty cool that Miatas are old enough to have their own vintage class and then also have one of the their own ambassadors:

  

Super excited for the season to play out at Thunderhill. Huge thanks to Josh and Cooper for keeping us safe all weekend , Meghan and Oliver for taking care of the snacks and the tire recycling. I love that event. CSRG is magical. If you haven’t been to one those events you ar emissing out, so come on out! WE’ll be posting out race scehule soon after the holidays.

 

CSRG Finale 11/1

ROB: Every year CSRG ends their season with the Finale at Thunderhill. This event is lightly attended and results in tons of track time. There’s an Enduro on Sunday with with a faux LeMans start… and it is just rad. The Saturday night dinner is a special event and we are seeing more and more people showing up. It’s been two years since I have had my Datsun 510 out and it was a great way to end the season racing it. 

 

Troy Ermish brought his 510 and we had a really nice B-Sedan field with a ton of Dimes out there. Most important 510s to us obviously include Tom Dockery and the return of fire captain Todd R,  Noah, Tom, Alison and Rob was out stable for the weekend:

 

It was just awesome having so much track time. Everybody was kicking ass and taking names, and by Sunday afternoon I think we’d all kind of figured that we’ve had enough track time which is unbelievable for us to say. Once again Josh and Cooper kept us all safe all weekend long and we rocked it. Oliver was on tire recycling duty and Meghan on snacks while enjoyed the small town feel of Willows.

  

We enjoyed Saturday night dinner with CSRG and it was so much fun to see everyone. I hadn’t seen Josh Moriarty in a long time and he was out there kicking ass in his 510. There was a really great group of these ex-GT3 cars (tube frame/ fiberglass bodies).  Jim Froula was in one (240SX) and a kid I run Spec Miata with (Joseph Carl) was out there with his Dad in a super cool vintage 1st-gen GTU RX-7.

ROB: We had perfect weather and another race reason in the books.  Can’t wait for 2026 we are super excited and will be traveling this year. There will be a big Japanese big-bore/bash with Sovren in the PNW and I’ll be going to the Rose Cup at PIR in my Miata. Get out there and race! If you have any questions/thoughts about racing with us please contact Rob at rob@zcargarge.com

Tom Dockery

 

Tom Dockery continues to enjoy racing in his Ex-Norm Balzer B-Sedan 510. Here is his report from both CSRG events along with some great in-car footage

TOM: The Sears Point Challenge was a fantastic weekend filled with learning and improvement. With Kenny, Noah, and me as students, Rob skillfully coached, challenged, and encouraged each of us to push our limits. As a result, I managed to improve my lap times with each session, achieving a new personal best at Sonoma.

 

The CSRG Finale at Thunderhill was fun, although it had its frustrating moments. We shared track time with the higher horsepower group 8 machines during all 10 sessions. The frustration stemmed from some group 8 drivers opting to start from the back of the field despite their qualification times. As they worked their way through the field, they didn’t always take the easiest path, requiring slower drivers like me to let them pass, which affected my race pace with competitors I hoped to stay with.

VIDEO

Volume up and enjoy. in-car video action from Tom Dockery’s Datsun 510!

 

TOM: There were positive aspects too. I learned the freight train signaling method to coordinate with teammates at the start. Noah and I used this technique to block a NASCAR Cup car that tried to prevent the faster B-Sedans from overtaking in the corners. Josh and Cooper provided excellent support on both weekends. At Thunderhill, Josh performed a fuel pump swap while Cooper replaced a lower radiator hose, ensuring we didn’t miss any sessions.

#72 Tom Dockery (Group 9)

TOM: The David Love event was an awesome kickoff to the 2025 race season. The Historic B-Sedan group had a solid turnout—about the same size and pace as the Vintage B-Sedan/Miata Group 3. Thanks to Rob’s fantastic coaching and support, I was able to set a personal best lap time on Sunday morning and held my spot in the top half of the group. I had a blast trading positions on track with Dave Stone, Glen Chiou, Kelvin Tse, and Jeff Rothman. Huge thanks to the ZCG team for their top-notch car support and coaching throughout the weekend.

Enjoy this in-car video from Tom’s 510:

Historic B & C Sedan

Fellow racer Glenn Chiou co-founded the Historic B&C Sedan (HBC) with Dave Stone. This is an organization dedicated to the racing exhibitions of 1966–1979 Historic SCCA B-Sedan, C-Sedan, Trans-Am Under-2-Liter, and Two-Five Challenge race cars:

GLENN: Since 2018, we have partnered with premier racing organizations such as the Velocity Invitational, CSRG, SVRA, and others to present thrilling run groups that celebrate these iconic machines. Our mission is rooted in honoring the history, camaraderie, and spirit of safe, respectful racing—with a healthy dose of serious fun. The David Love Vintage Races were a perfect showcase of that mission. With around twenty historic sedans in attendance—including Alfa, BMW, Datsun, Mini, and more—we delivered an exhilarating exhibition of vintage racing. Partnering with CSRG and Sonoma Raceway made for a fantastic weekend shared with friends and family.While the David Love Vintage Races was HBC’s only event for 2025, we have big plans for 2026!

To learn more about HBC, our events, the cars, and the stories behind them, visit our website:

The Historic B and C Sedan race was one of the most exciting run groups and Race car driver/Datsun Historian Glenn Chiou raced his Ex-Bob Finn U2.5L Trans-Am Datsun 510. This car features our Z Car Garage CV Axles and dyno tuning:

 

It’s worth noting that not unlike privateers of the period, Glenn builds his race cars, maintains and manages racing efforts himself. Not an easy task so we applaud his work ethic. Glenn builds some beautiful Datsuns and we thank him for organizing the Historic B&C Sedan group to keep the spirit of Trans Am racing alive.

 

Rob Fuller recaps the event:

ROB: Ross Lindell was in the Randy Pobst National Championship-winning Miata (1992), Lora in her Miata and myself my Miata for Vintage Spec Miata. For Datsuns there was the special HBC run group that was super fun. Kenny and Noah were cooking. Kenny, Noah and Tom Dockery all got their PBs. It felt really great to get the Miata back on the track again. Lora was passing people for the first time, that’s huge milestone. We had just gone through Ross’ car and he was super happy with the setup and dyno tune. The weather was absolutely perfect and the run groups filled with beautiful cars. Glenn was out there,  Frank Z in his 510, Alfa boys Chet Taylor from SoCal. Wonderful weekend with good times had by all. The Corkscew Classic event at Laguna Seca  is coming up next. Don’t mis these (FREE) family-friendly events!

Overall, the race weekend at Sonoma Raceway for the David Love Vintage Races was a memorable experience filled with camaraderie, competition, and personal achievement. I was able to achieve my fastest lap time yet at Sonoma and successfully obtained my full competition license, which was a hard- fought goal. I’m so happy that I kept pushing through and finally achieved that milestone!  I am so thankful for all the encouragement and coaching I have received from Rob Fuller and the team. I hope to be an encouragement to all that I meet, to continue to follow their bliss and achieve their dreams.

A Fan-Friendly Race Event

 

The CSRG events are all FREE to spectators, so bring your family and friends! Lora recalls a memorable moment:

“One of the highlights was meeting a little boy who was celebrating his fourth birthday. All he wanted was to come to the racetrack and see a race car for his birthday. It was so heartwarming to share that moment with him, and he even asked for a picture with my race car and with me, the “race car driver”! It was such a surreal and adorable experience. I think my red Miata must remind children of the red car from the Disney movie Cars! That moment was so unexpected and enjoyable”

Super cool to see our client Linda Williams’ 1972 Datsun 240Z OMS Pace Car Duplicate participating in the John Streets Memorial parade lap aside fellow Datsuns/Nissans.
