I know for sure that the 300mm Hi Spec rotors and billet 4 calipers will fit under 15" wheels as I saw them on the P4 before he converted to Impreza power and drivetrain. The bells in the pic were fitted to the car too so I know it will work although apparently its a tight fit. I was rather hoping that I could make up some brackets based on the drawings and then just buy the calipers and rotors from Hi Spec. Its doable I'll need to try to make a pattern for the brackets myself rather than just handing someone the drawings by the look of it.
The bells that I have are designed to be a floating mount. I have had some special bobbins made to join the rotor and the bell which allow for differential expansion of the alloy bell and steel rotor. The slots allow movement of the 2 parts against each other as they expand with heat which prevents cracking. Quite a clever solution although I can't take any credit for it, all designed by the guy I bought them from.
