I just purchased an AE71 Corolla and its sitting on 14" Lonchamp XR4's with Koni Adjustable fronts with Lovell springs on the front. The car is at legal height but only just clears the guards The issue i am having is that the guards are rubbing the wheels on bumps and speed bumps What is my best way around this? Lower profile tyres? Raise the car? Any advice will be appreciated Thanks
