Sorry for the caps in the title... but.....

Does anyone know where the 4 thin steel washers go as part of the 330mm Prodrive upgrade?

Just fitting the upgrade, and not entirely sure where they fit.........

Also, can anyone confirm that the thin steel gaurd behind the disc is no longer used?

Appreciate an quick answer PLEASE. I seem to remember someone on here working for a dealer.

Does anyone know of a dealer open today who might be able to assist?

Thanks very much indeed!

Not done a Prodrive brake upgrade but I have fitted AP's to mine.

The thin steel washers are likely to be shims, you use them between the caliper mount and the hub, or between the hub and any adaptor, to move the caliper side to side. You fit the shims to get the caliper exactly central over the disc.

Fit it all with no shims (and no pads) then look down through the back of the caliper at the gaps between the sides of the discs and the inside edges of the caliper. If you have a 2mm gap one side and a 3mm gap the other fitting a 0.5mm shim will give you 2.5mm each side. Helps the pads to wear evenly and get maximum life from the pads.

Sorry, forgot you asked about the steel guard too. Took mine off to get clearance. It's no more than a water splash thing I think. I've run without one for 5 years, no problem. Speaking to someone recently they said they on the GpN rally cars they just bend the front out at 45 degs and it helps to get some cold air flowing into the middle of the disc.
