Factory 10 inch brake rotors and 54mm calipers never had a chance of stopping the car given it’s increased mass and potential for violent acceleration. Several Audi models came equipped with dual piston Girling 60 calipers and I chose to stick these on the car.
Cost breakdown:
-Girling 60 calipers and adapters $80 - local friend - used -Coraddo 11 inch 4 lug rotors $85 - local parts supplier -Hawk HPS brake pads $95 - ebay
