I have my 20" Advan GT wheels with 285/335 for the street and want to get an 18" setup that I can rotate for the track. I've searched but seems there's a lot of info out there and nothing concise, so sorry if it's been hashed out already.
What size 18" wheels would I need to be able to fit them front and rear and rotate them for longer tire life? I thought i saw 18x10.5 +25 as the sweet spot. I assume I'll need a spacer in the rear?
Also, how has reliability been for you guys who track a lot? Any issues or problems with the motor or transmission?
So far I've tracked relatively lightly but going to start doing it more. Current power mods are HKS mid pipe and HKS legamax. I'm about to install COBB Big SF intakes and a COBB OTS tune, but that might do it for me... car is already a monster on the track with those mods
