Decided to have my calipers painted (front and rear) to smarten them up. Two recommendations for you:
Firstly, E-Tech caliper paint from Amazon. Excellent results, now gloss black (less chavvy), looks the dogs now.
Secondly, bought the Audi roundels stickers from the TT Shop on line. Excellent service. Ordered Sunday, delivered Tuesday morning.
Roll on AITP 2013!
