First off, this is just at idea stage, it is not a commercial venture nor is it presently for sale. I have purchased a pair of accord type r calipers, these fit direct to the MGZS and Civic with 262/282 front brakes. The big problem is finding some 300mm discs that fit properly, and that are 28mm wide like the calipers were designed for. And doing this without dangerous spacers, washers, shims or bodges. The answer seems to lye in getting the correct disc that is a perfect fit. I am looking into the possibility of getting the discs made up from a blank casting - so the end product will not be redrilled, not need spacers or shims or spigott rings, it would simply be a 300mm disc, 28mm wide that would fit correctly and without modification. These would be (subject to final agreement) manufactured by the same company that made the discs for rover MG, Brembo, EBC and others, so of tier 1 quality. So you could use this 300mm disc, accord type r calipers and pads and have a complete 300mm atr type brake setup that fits without any mods - under 16" rims tho. Question is, would this be of interest to anyone (the custom discs that is), or should I not even bother going down this road?
