Offset
 

I'm looking to put a set of 18s on my 93. Possibly 18s on front and 19s on the rear. The question I have is, what offset do I need for the front and back wheels for them to fit, function, and look right? An answer just for the 18s would be fine. I prefer not to flare the fenders but please if anyone has info they can share, I'd greatly appreciate it. She looks like a sleeper and that was fun for years but she needs some new shoes to help her hook consistently. She's working with a built LS1. Heads, Cam, intake, exhaust and Z06 intervals. And yes, the right tires will hook on stock r1 rims... Just not very well. It's a fine art to peddle her.
