Have we ever discussed the effects of changing the wheel/tire sizes and the effects on acceleration, both in starting and stopping? I ended up using 195/55/15's on mine and I noticed that the speedo was off about 10% and I expected that and because the overall diameter was smaller, i thought acceleration would be affected slightly also. What I didn't take into account was the rotating mass effect. So, I guess my starting and stopping both have been slightly improved, maybe handling is improved slightly also.
