Alright, i want to do a disc converssion at the rear of my S2, and upgrade the fronts. Thing is my Dad broke an XR4X4 not long ago because some one went into the back of it and he told me he stil has all the discs and calipers left, can i use the rear ones for a conversion on mine?? He says he thinks the fronts are the same as a RST any way so not much point there, ill most likely go down the usual cosworth route there.

Im all new to RS Turbos so i want to learn about them!!

Thanks... Selby
