Sold: R56 Cooper S Brake Calipers for your R56 or R53. The Gen 1 JCW Sport Brake kit featured the same calipers that became standard on the R56 Cooper S. New JCW kits are hard to find so many people try to piece together their own. Here I've done the hard work for you. These calipers bolt straight on to your R50/R52/R53 MINI (you do need to buy larger rotors, however.) Offered up for sale is a pair of stock R56 calipers, painted with red ceramic paint. (Because, red....) Calipers were just rebuilt with new seals, dust boots, and bellows. They also come with used Brembo street performance pads that have about 90% of pad remaining.
