When test driving the S2000 it seemed fairly easy to break the rear tires free on the car. Wondering if I install 18's if I then won't be able to do so any longer. Sure is fun to hear those tires chirp when pounding gears and feel the rear of the car come out from under you once in a while! If I put 18"Potenzas on will I lose all the fun?

 

Well for me it would take the fun not because of that... but because I'd be worried constantly if a bump or a pothole will take the rim out or not.

For me 17" would be a good compromise.
