Car is a 1991 MX5 with an LS1 and T56 from a 2000 Z28...Flyin' Miatas subframe, 3.45 gears, currently has 15x6 (?) wheels with 205/50R15 Kumho Ecstas. As you might guess, the engine has no problem overpowering these tires...they're also worn out, and the rims (bought used) are scuffed and scraped. Considering 15x8 wheels; a 225/50 is about the biggest that will fit (might end up with a 215/50 in front). So...who makes a light 15x8 wheel with a 4x100mm lug pattern? Alternately...16's...? Suggestions?
