Re: Tire advice
Corsa is available from Tirerack and Discount in 335/30R18 in a (Y) speed rating. Thinking about Rosso in front and Corsa in the rear.

Re: Tire advice
Yeah, I used these on my supercharged 2013 GS in the rear, and they worked very well. Best of the "streetable" track tires I've ever used. Handled the 700rwhp in my GS pretty well, so thinking they should handle 391 motor's power pretty well.

Re: Tire advice
Evan,
There’s a standing mile HP calculator at the bottom of this page. Just playing w some SWAG figures, u would need another ~ 100hp to jump 10mph in trap. Give it a play: https://www.rbracing-rsr.com/aerohpcalc.html

Re: Tire advice
Well 100HP is certainly doable, just throw a small nitrous setup on it.

Re: Tire advice
Evan, what 18" rear tires are your competitors running, for those speeds? I'm assuming you are running 335/30/18's, now. Still have a 3.45 rear gear?

Re: Tire advice
Yes, I'm on 335/30/18 rears, and still running the stock 3.45 rear gear. No real competitors in C4s that I've seen at the events I've been to. Most Vettes at these events are C6/7, with a few C5s, and almost no C4s.
