For guys running Wilwood, Brembo (RS), and other Aftermarket calipers and big brake kits, does this limit your pad options? Or can you still get just about any pad from popular manufacturers like EBC, Hawk, Wagner, etc, etc? Or are you stuck with the caliper manufacturers pads? Seriously eyeballing that Wilwood 14" set up. I know it comes with good pads but was thinking about the future.
