You can put a piece of wood behind them and hammer the lip at the outer edge flat. Easy peasy.I am in the UK. My brakes are being fitted on Saturday so will post some pictures when they are fitted. The rear dust shield is a pain to fit on because will need to remove the main hub and thus replace bearings ect.. Does anyone know if the rear dust shields are exactly the same size? used on the the non-performance pack and performance pack or are the part numbers different? If I can get away without replacing the rear I would! would definitely save loads on labour then?
