As far as my brakes are concerned, they are sold unfortunately, BUT, i would definitely have a set powder coated again. they look as fresh as they did when i fitted them. Being white, you might think they were a pig to clean, but not at all. some good wheel cleaner, a pressure washer and your rocking!
Honestly VC, they are brilliant.
What i did was get dave to send me a new set of calipers powder coated in white, then swap my calipers with the new ones, then sent dave the old ones plus some cash! great job!
