I will be needing new discs all round in the summer for my 55 DTM. I want to take the opportunity to put some decent pads, braided hoses and better brake fluid but also wanted to look at the options on the disc/calipers? i don't have the budget to go for the RS4 setup but I have read that the 3.0 tdi has larger discs and with a new caliper carrier I can use my existing calipers? Is this true? What have others done?
