well first of all, i dont really race nor go to the track for times...yet. i just wanna know how much 17"s that weigh about 21lbs + tires will affect my acceleration...i mean am i going to notice a huge difference in the way my car accelerates/handles or would it only be slightly differnt were u cant really tell. sorry for my kinda blah questions, but i just wanna make sure i've got all the facts down before i make my lil investment. thanks
