The Tourer rear discs have a drum handbrake mechanism inside them, so are very different to the Saloon, also the pads although very similar, are different too. the Saloon pads have a pin on them to engage in the piston, if you try to force these into the Tourer you will have problems. Either make sure you have the right pads or file the pin off. I have changed all my discs and pads (Tourer) to EBC and find them perfectly good, no noticable difference from standard, apart from the price!! I got mine from brakes4u and got good service, price and exactly the right parts turned up.
