Hello all. First post to Corvetteforum, and looking for a little guidance from experienced track-day drivers. I currently track a late model Mustang GT, and I'm looking to upgrade to a C6 Vette for increased performance potential. I would prefer a Z06 or a Grand Sport, but my budget may limit me to an '05-'07 LS2 model. Since the LS2 is a wet sump sump engine, I have some concerns. I understand that above 1.2Gs, the wet sump is inadequate. Can a lightly-modified, well-driven C6 come close to 1.2Gs on good street tires (like BFG Rivals or Bridgestone RE-11s)? Or is this only achievable with much stickier tires (slicks)?

I appreciate the help. Thanks!

Welcome... you will not get to those #s with that rubbrer. You can find ALOT of good info here.Look in the road racing section stickies for information. Best advice on cars-engine choices ect.

Is3 and dot race rubber is the problem. Gs and z06 have drysumps so ok. Ls2 and ls6 are very close performancewise.

My C5Z does 1.2 on RE-11's. I doubt you'll have an issue unless you run it somewhere like Daytona, but I'll let others chime in on that.

C5Z is probably better than an C6 with either the LS2 or 3. You can get into one for a little less money, add Ron Davis Racing Radiator with Engine Oil Cooler, Diff and tranny cooling, upgrade the brakes, add a cam and be competitive with the C6Zs. The LS6 is a strong HPDE engine that can take a beating and just keep coming back for more beatings. As long as you don't get a higher mile babied car the engine should hold up fine.

All good advice. Thank you.

C5Z is the easy-button HPDE car. With the money you save by not going the C6 route, you can fix the track-specific deficiencies easily as Bill mentioned.

I don't know about the tires you suggested but my 2011 Z06 would develop 1.2 Gs in some corners in stock configuration with the Michelin PS2s the factory put on. The car is still stock and I've switched to Michelin Cup tires. It's a bit easier, and more expensive, to corner at 1.2 now but no oiling issues and you don't have to spend money on any other modifications. The new Michelin Super Sport tires are even better than the PS2s.
