What does a highly modified GT-R, a wild 1967 Camaro, a bone-stock Ferrari, a magazine-famous 370Z NISMO, a Supra that enticed a newcomer with a free track day and an LMP3 prototype have in common? They all went on to wins at Super Lap Battle.
The race put on by Global Time Attack took place at the Circuit of …
What item got Sutton moved from Limited to Unlimited?
In reply to Andy Hollis :
I believe it was suspension. I'm confirming that now.

That sounds right. I recall the announcers saying something about non-OE dynamic suspension...dampers specifically.
Any photos of Shawn Bassett's wild 240Z build?? The fast vintage cars interest me more than the newer and (much) more expensive machinery. The average guy can afford a Nissan 350Z, 240Z, and maybe an older Camaro like Cody Puckett's, but the Ferrari, McLaren, Skyline, etc., are too pricey for most folks. I shall buy all of them next month, but of course this is before then so, any photos of that 240Z?
In reply to Andy Hollis :
Confirmed. He had aftermarket electronically controlled shocks. However, they embraced it, got some racing slicks, and then made the podium. Well done.
In reply to DavyZ :
Yes! Expect more on the '67 Camaro of Mike Dusold soon. And we're working on doing more on the Datsun. Both are wildly modified, but have retro-cool looks.
I'm not so sure how much cheaper these builds are though than some of the newer ones (not the McLaren or Ferrari, of course). But I can understand their appeal, certainly.
From Louis at GSpeed, builders of Eric Fleming's Unlimited Corvette...lots of insight here.
What a weekend at COTA Super Lap Battle We're so proud of Eric Fleming and the team for everything they do!
Without further ado, a message from Louis.
"A few months ago, we decided to make a few changes to Eric Flemings C6Z. I share a lot of the progress and ideas on a few other groups, but have yet to share it to my personal page. This was the car that we tested methanol on a few months ago (with out success) so you have an idea of how hard we have worked to get this monster to the pointy end of lap times, especially at COTA this past weekend at Super Lap Battle.
The premise is simple. In the unlimited class, it must be a mass produced vehicle with a VIN. No tube chassis or factory built cars. That’s basically it.
Given our success with Trans Am and NASA here, we were able to “speculate” a laptime based off real world segment and sector times that blended the mechanical grip of those low power, heavily restricted corvettes, and the power, aero, and weight reduction of a “theoretical” unlimited build.
With a professional driver (ie, current champion, IMSA race winner, or paid hot shoe) that blending of sector times showed that we could achieve a 1:55:00 or better with about 1300whp. That’s about 8 seconds faster than LMGTE AM, 5 seconds faster than LMGTE Pro, 1 second slower than LMP2, 9 seconds slower than Indycar and LMP1 when they ran here last and 22 seconds slower than F1.
Those openwheel and professional GT efforts have tens and hundreds of millions of dollars behind them driven by the best of the best drivers in the world.
We set out in the fall of last year to Atleast move the needle considerably on Eric’s car. For reference, this event last year at COTA with about 5 laps under his belt, on street tires, he went a 2:12.2….. that’s deep in the TA2 field, time wise, On street tires. Lol.
This winters updates included:
Zebulon MSC Ltd. Aero package
Motec firmware update to manage the Addition of paddle shift
Intake manifold change that netted a 130whp increase at 8400 rpm( yes, the filter sticks out of the hood, my hands are tied and I’m actively trying to solve that, lol)
Addition of Michelin Slicks
Exhaust system update to accommodate the flat floor
And a whole slew of little details to improve the car and driving experience.
Last week, we shook the car down at Cresson with Eric Foss behind the wheel and on a scrub tire, we went a 1:08.3, but we had some work to do searching for front grip.
Wrap, updated chassis setup, spring change, and finesse the whole car, and we headed to COTA early to test.
First timed lap we found a lot of tire rub, which was odd…. But maybe the changes added some front grip.
Sure enough, the aero push had gone away.
The next 8 sessions we fought a broken diff, a paddle shift actuator malfunction (my mistake) and made improvements every session until the end of the day Sunday when we fought the track and an oil down.
The end result was a 2:03.853. Driven by Eric Fleming.
Eric Foss did a phenomenal job of data analysis and video critique to help us pick seconds and then tenths out of this package all weekend.
What a ride. The team did great, the car did real nice. Juggling fuel, tire warmers, maintenance between sessions and any chassis changes is a challenging task, and they didn’t miss a beat and the results back that up. Thanks to Ian McMasters, Rodolfo Valero, Jason SmithJon Simpson, Devon Larson, Photog Nate Grady for killing it at the track all weekend. Special thanks to the shop crew who didn’t travel, Chase Borden Justin Taylor Clark, Vinh Nguyen Michael Alexander Cargile, Dakota Robbins, Xavier Price, Patricia Bartley, Cole Wallace, Zack Prell, Kris King Paul Costas
The car run down as of this weekend is:
2007 C6Z

Michelin S8 slick (30/68F 31/71R)
Samsonas Sequential gearbox paddle shifted
Motec GPRP pro firmware calibrated in house
Cockpit adjustable blade sway bars (50mmF bar, 38mm rear bar)
Q16 fuel
Penske shelf damper (she’s maxed now, lol)
Packer setup from RE suspension (this is VERY IMPORTANT on getting the maximum out of an aero car)
Countless hours of time on the setup pad.
Essex Parts Services, Inc. AP brake kit
Cobalt Racing Brakes XR1 pads
Tilton Engineering pedal box
Stock C6z diff lol
Thanks to my wife and family for putting up with me the last month as I worked my fingers to the bone.
Thanks to Eric Fleming for trusting and believe in us. We built this latest rendition mostly through text. I think we talked 2x just sorting out tire issues.
Thanks to Ryan Neff for the guidance and support. The aero is great, the after sale support is even better. It took me about 5 years to buy something from, and the worst part about it was realizing that I should have done it sooner… all Thanks to Jake Latham
Thanks dad Lou Gigliotti for the chicken hawk tire warmers, we ended up having 2 sets, but thankfully we had them both as a controller on each set failed, so it worked out.
A.J. Petersen thanks for the last minute tires and scrubs. Your attention to detail allowed us to test on known quantity scrubs with out burning up stickers.
Eric Uriarte and G1design, killed the last minute wrap. If you need a wrap in DFW, Eric gets it. And delivers.
Geoff Miller, this would not have been possible with out your guidance with the Penske Dampers and recommended packers. Thank you.
Lastly, to all of our customers that have believed in us the last 10 years, thank you. Your trust and dedication to our efforts allowed us to build a car with a decade of learning and not making the same mistake twice. New mistakes were made! But you can rest assured that they won’t be made again."
In reply to Andy Hollis :
Great insight. Thank you for sharing.
One more important thing to note. Eric and his team did this all with a naturally aspirated engine. Very few cars go that route. I spoke with the engine tuner and he told me next year they may add a turbo or, if he has his way, go with a bigger engine for more power. He prefers the simplicity of a naturally aspirated engine. Although, there's nothing simple about the engine under the hood of that Corvette.
