He was lowered a fair amount with H&R coilovers from what I remember. 285/30-18 that's a lot of tire for a little car. Would be good for a race car but I'm thinking might be a bit much for street driving. I would think it would "track" / pull all over the place with groves in the roadway. The 17x8.5 +50 wheel would look nice to me w/ 255/40-17 tire.

Thanks again,

PS. Sure like to see in person that little yellow car maybe go for a ride in a real race car? Thanks for all your insight.

I didn't realize we were rubbing the inside until after about a year of competition when I noticed that the underbody coating was gone on a 2x2 inch patch of bare metal inside both rear wheel wells to the inside. I have had a few customers tell me similar setups "don't rub" and we jack up and pull the wheel and they are always surprised to see that bare metal....

That's funny... I try on my MX5 GT the BBS 18x8.5 +55mm 21lbs who come OEM in the Subaru STi 08+, they fit perfectly on our car without any rubbing, the tire was the big 245-35-18 ! After this test, I was thinking about the Ultraleggera 18x9 +55mm 19lbs... 285-30-18 with this wheel maybe fit without rubbing ? Anyway, it could be another wheel option ! STi wheels... Yeah that's crazy, but it's works !
