For Sale: Carbotech brake pads for Stock R50/R53 calipers. If you haven't tried these on the track, you must. They are amazing. XP-10 compound in the fronts, XP-8 in the rear. If you're thinking about getting a big brake kit, these might just change your mind. New in original box. Note: They do not have the cut-out for the brake wear sensors so you have to monitor pad wear. You don't want to run them to the backing plates or the rivets will groove your rotors badly. Paypal preferred, PM if interested or any questions. $195 front/$175 rear including shipping to lower 48. $360 for both.
