it's a slightly more expensive option.. but if you ask me far better, as you kill 2 birds with 1 stone.. lowered car excessivly = bump steer city.. to you need RCA's right? (right).. get neg camber RCA's..
plus if you like me.. you would have done the smart thing buy now and rebushed everything in the car with a good quality urethane bushes and replaced all your ball joints/rackends..
