Enkei RPF1's-little pricey but one of the lightest wheels made. I'm a noob so I am regurgitating what other people say, but there are tons of 240/350/370 guys atthe track events I go to(yay Corner 3!) . Pretty much every serious track 350/370 I see runs 18's/10.5". Most of the guys use 285 RS3's or they swap to Nittos for their time attack events.
As for transporting them, you can swap them the night before-unless they are not DOT compliant. Otherwise, you need to get a GF with an SUV
