C2 of Year Finalist (track prepared) 2019
Superformance GS
Looking at this picture, it appears to me that the windshield doesn't have the curvature of the real cars, and the A pillar is also considerably wider. Now, I've never seen one of these cars in person, so it could be the image I scanned. I think it looks odd though.

There are a lot of things wrong with that car. It surprises me because Superformance did such a great job with the Daytona coupe. The cars on the web site don't seem a lot better.
I think of this as some sort of Resto-Mod. It's really not a replica.

Can't tell about the windshield curvature, Larry, but the A-pillar just looks strange.....

Guys,
Thought you'd like to see how the GS 'bar' emblem that I produced for Larry's amazing #004 recreation turned out.
Took longer to produce than I thought and there were one or two hiccups along the way but, it's as near as dammit to the original in size, typestyle and profile.
The smaller image with the ruler is from the original #004 (courtesy of Richard Newton, thanks again Richard for your help on this one)
Thanks also to Jim for your assistance.

Wasn't the race car of 1963 called the "Lightweight"?
Shouldn't our "GS's" be referred to as "lightweights" instead of Grand Sports. The Grand Sports Almost sounds like a Marketing name instead of an actual name Zora/GM Engineers would have used. (i.e.: CERV)
Even built off an original Corvette, with the ladder frame and the other items the weight is still easily sub 3000 pounds. It could still easily retain the lightweight moniker.
It would certainly distinguish between a C2 and a C4, .....
Thoughts?

FWIW, Ty, on the layout drawing for the frame, the name is "Light Weight Corvette".
As far as referring to our cars as "lightweights", well, in some circles I do refer to my MAI car as "The Lightweight". I've spent a lot of effort to make it true to that nickname so I feel somewhat justified.
Some replicas, however, scarcely weigh less than production Corvettes. In my not-always-humble opinion, it would do a dis-service to the concept to refer to them as lightweights..... but that's just me.

I've never heard any of the original driver's use the term Grand Sport. They've alway refereed to them as the Lightweight Corvette.
We're just going to have to live with both monikers.

Looks good, Larry. Remember they even drilled the trailing arm alignment shims. Nothing was spared. Had I mentioned they also drilled the Z-bar?
BTW, for my own lightening program, I always weighed the before and after to get a sense of how much weight I was removing. I saved 1/2 lb by eliminating all the unneeded wires from the main, under dash wiring harness.
Did you happen to weigh that assembly before/after?

I did the z-bar last year, and did the teardrop cut out of the steel core support for cooler lines pass through.

Bouncing some ideas around, would love to have dialog.
To all:
I am wanting to run my car in the Ultimate Street Car Competition when finished with my GS and I am trying to plan the build in some respects to be competitive in the competition.
There two classes I can enter and at least have a car capable of being on par with others. (Driving aside)
Over 3200 pound minimum weight Vintage, or "Open" class which has no minimum weight but includes AWD's and others cars with fully computerized active suspensions.
What are the widest tires one can mount on their GS?
My thoughts initially are to run in the Vintage class at a goal of 3201 pounds, retro fitting ABS and Traction Control if possible, then adding weight to car as low and properly placed on the chassis as possible to increase handling.
Is there anyway to run 315's on all four corners without tearing up the fenders? I've seen small extensions added to the rear fenders to help accommodate larger than 275 rear tires.
BTW: With the C4 suspension having corvette hubs, and running a LS3 do you know anyone who has been able to get this to work, or offers a kit of some kind?
Also which Traction Control System would you recommend?
Thanks,
Ty O'Neal
