So im under my car today raplcing a leaking exhaust gasket when i notice that my pretty FRPP aluminium drive shaft has a nice deep gouge in it frim where it had apparently been rubbing on the underside of the car.its actually hitting on a bracket in two places about 3/4 of the way towards the rearend. Any suggestions on this one? i mean the car has been lowered with eibach sportlines and tokiko illuminas but i would like to keep them. Also the car is on 225's right now but im not sure how big i can go without rubbing back or front.
