It really comes down to your priorities and application. I built a spreadsheet a couple years ago so I could lay it all out knowing full well I was not prepared to buy. I only considered platform specific bbks with complimentary front/rear setups. My rims are forged 18" so easy fitmet. I don't have that data atm but some highlights are: Stoptech: most popular and easily sourced AP: race reputation, street overkill, most impressive KSport: piston galore, newer player Brembo/Wilwood: industry standouts with several stages RacingBrakes: small dedicated company, impressive line up. For me, the most well matched street package (although the logo is goofy).
