Doing that, you've effectivly changed your 4.10 to 3.92's. The 255's were 30.1" tall and the 285's are 31.5" tall, you should be able to feel that and you've probably lost some low end.

Yeah, its much slower around town now. I still have my stockers for racing but I think I will keep the 18s on for looks around town.
