I had the front and rear cambers set up by Xtreme Motorsport which is near Alrewas, just off the A38. He used to run Clio Cup racers and had the rear shims in stock. The front camber bolts he used on my car are actually 14mm so the hub and front strut had to be drilled out to suit. All in with the shims, machining and set up came to around £200.
The fronts are currently -2.5 deg and the rears are - 2.0 deg with a bit more toe in to suit.
