If you prefer a brand name like Brembo for its racing heritage, you might look there. However, for the same money, you get smaller rotors and fewer included parts. Baer kits often offer more color options for calipers. But for pure performance and value, the Wilwood kit from Accesspeed is very hard to beat.
