Im going to be fiting my 308 brakes soon and also fit the brake ducts that fit to the wishbone, but ive also seen you can get the auxiliary ones that are fitted to the coupe turbo which you need the splitter from and the ducts, is it also worth doing this and what sort of cost would it be for the bits from vauxhall?
I have these part numbers if its any use
