I've got an 80mm drop on my mk2 & I didn't have any rubbing with the Std 185/60/14R wheels.I fitted alloys with 185/45/14R tyres & the car is much lower still no rubbing & it just goes on the MOT brake tester,biggest problem was getting it on the MOT ramp & using the jacks.
Have you got lowered or knackered top mounts?
