I just bought a fox and it currently has coil overs "I don't know the brand yet" and because of that in needs a spacer to keep the tires off of them. That pushes the tire too close to the fender and causes the tires to rub if you are turning and braking at the same time. If changing the spindles would help that I would like to do it. The car has a coyote engine so much work has been done in the front.
