hopefully Hyper will chime in. He said he had the 4 pots on his old forrester and now has brembos front and rear. i don't what the rear of the forrester was. he said there was no comparision.
i have gone from 1 pot 9" front brakes to the 4 pot 11" brakes on the front and the diffrerence is immense. i don't plan to go to brembos because i run 15" and 16" wheels. and my 17" wheels don't clear brembos.
