Washing the car I noticed that the wheel arch liners under the front wings are distorted, maybe by the fitting of the side steps/front mud-flaps, it's so bad that the one on the drivers side pops out and I have to tuck it back in occasionally (oh err vicar) for want of a better description. Garage I bought it from suggested that they shrink a couple of mm over time - not vey likely IMHO!
Anybody had similar problems? Geoff
