im going to run 15" SSR knockoffs (10 lbs) with falken azenis for autox and 17" wheels for the street. i would run 14s but apparently they dont fit over the brakes. so 15 it is. about ride...a lot of it comes down to tires. i had 14" wheels with yokohama grand prix (r-compound) tires and they were "ouch"
when paired with my suspension. but it was fun!
