Hi, ive uprated my back brakes on my s1 to 273mm cossie discs, during a 3 year rebuild. I had greenstuff front pads and drilled and grooved discs on the front, i thought they would work well but found out the hard way!
Now the cars been fixed ive got a set of 2wd cossie 4 pot calipers on the way for the front, can any one tell me what set up would be the best, bias valve?? What discs?? any advice would be great cheeRS
