I'm going to get some wheels and tires. I'll prefer 18" coz I'll go NASA open track race. I found a set Y2K 18" replica wheel for cheap. Is it good to run 275/40/18 all 4 corners? I don't really want stagger tires coz they can't rotate. If stagger is better, how about 245/45/18 in front 275/40/18 rear?

I can't do any 17" wheel in the front coz I've C5 brake, and soon will be C6 Z51 brake. With 12.8" rotor and C5 caliper, what wheel offset should I look for?

if you go 275/40/18 you need to have your speedo calibrated. I have KDW in 275/40/18 on all 4 corners (there is a little rubbing on the front wheel well, even on stock ride height, bang it in a little). I would recommend getting a wider tire in the back something like 315 or even 335's. I didnt know that with the C5 brakes you cant run 17's. I'd double check that. The ideal set up is 17" wheels with 275 in front and 315's in the back.

Well, it'll be lower for at least 1"-1.25" for handling and look. So will 275/40/18 in the front rub the hell out of it?

I do alot of research here and 100% sure C5 brake will need 18 wheel. Some 17 might work depends on offset. But I'll go for C6 Z51 (13.5 rotor) later this year so 18 front will be a must. That's why I ask about the offset to clear the brake.
