there brakes are ok for oem kind only company i wont use agaiin is ssbc there rear disc the parking brake wouldnt work. and i adjusted it all the way it would go and they was no help to fix it i ebayed them. wilwoods are more but there rotors are thicker and there cailpers have more pistons so more stopping power.i do have a question for you did you buy a new master cylinder your old one wont work with 4 wheel disc.
