I couldn't agree more. J55's are way under rated and with modern high performance pads they really perform well. When I installed my GS J55 calipers last year I opted for PowerStop Z26 Street Performance pads and rotors. The difference from stock pads is remarkable. C5/C6 Calipers have little advantage over a good J55 setup. Larger calipers like the C6 Z06 and other Brembo, Wilwood or Baer setups are good, but for the cost and installation headaches (parking brake) they are only an advantage if you track or autocross the car. But hey, if people like the look or feel the need for every ounce braking performance they can spend their money however they like! It's still a free country (for now).
