i bought the car with everything on it already and i can see it has bbk lowering springs on it...but i want to change the wheels...it has 17" cobras with 245/40/17s on both front and back and on full lock the fronts rub the lowers c/arms a little bit. i want to put 17x9 SC replicas on the front and 17x10 on the rear if possible. how do i know if they will fit my particular setup? also my exhaust dumps b4 the rear axle so its not in the way. thanks
