Honestly, the best place to buy brake components and kits from is Dave Zeckhausen. Not only is he an avid BMW enthusiast, but he is extremely knowledgeable about anything brakes. I have met him several times personally and he truly is the real deal. Check out www.zeckhasuen.com and give Dave a call - he will set you up with the right combination for your car all for a good price and with excellent customer service.
