Im in the middle of deciding what to do with the brakes on my S3. the rears have alot of life left in them yet but as part of a winter overhal i need to improve them. What is the brake bias on these cars? ive NEVER had the car lock up, fronts or rears. The brembos up front will stop the car once or twice from speed. after that... no joy until ive let it all cool down for a hour or so. Do i fit 300 rears? or do the rears basicaly hold the car on a hill when you pull the handbrake up?
