does anybody know the weight of the stock rims? the rear and front wheels and tires? im thining of getting 19" konig rims... the rim alone is about 24.2 lbs.. and im gonna run a 245/35, 275/35 set up... what im REALLY concerned about is this having an effect on my acceleration! i have intake and exhaust (kinetix plenum and HFC coming soon) will this cancel out my mods?
