ok i have a 95 del sol with a b16, i/h/e, and the car feels like a slug. more so on bottom end power. i know it doesnt have alot of torque but geez i gotta get moving. i have tenzo r rims that are 17s and are about 3 years old so i dont know if they sre still made. im currently out of the country so i cant remember what style they are. i lost to a 2005 civic si by a little but he was stock. im not sure but i think the rim is 18 to 20 lbs. i could be totally off though. let me know if this is the problem. also what size rim and weight i should buy and how much a difference it would really make. thanks for the help.
