I have an older MKIV build, I purchased used. I raised the ride height 1/2" last summer, to address a tire rub concern in corners, at the front. I have the Koni's adjusted to where the collar just barely touches the spring at full droop. This corrected the front right tire rub, but it still can rub on the front left (right hand turns). I am pretty sure I should not try and raise it more, creating a gap btwn the collar, and spring, at full droop? What about spring rubber spacers? Any ideas? Again, would like to fix the tire rub, but I seem to be out of adjustment. ride height is around 4" front, 4/5" rear. Why would only one of the two front tires rub? Camber seems identical.
