Ok so I cant find a close answer to my situation. First off my car is RHD so changing the pedal ratio isn't exactly the same as everyone else. Second I am running a 5 lug swap. E36M front calipers with E46 325i rear calipers and a E32 750iL master. I like the feeling it has now. Pretty close to stock feel but I need some room in the engine bay and deleting the booster is one of the only ways to go. I was looking into chase bays full booster/ABS delete kit and I believe the recommend a 21-22mm master for the E30? cant really remember But I'm just afraid I am going to have a pedal that is either to hard or to soft with the calipers I am running. Anyone have any input?
