Anybody out there ever taken the early model 205 gti on the track with the stock brakes. Does the car do alright with them? I was just wondering how much of a difference rear breaks will do to my stopping distance. I've been told before that the drums are alright on the 205 coz its so light. What does it cost to convert to discs anyway and is it easy? Do I need to upgrade the main booster thingy? Other question: Is it worth getting greenstuff pads as everyone seems to think here? What is the difference between greenstuff and stock pads? Is it about wearability?
