rotors are likely good quality. The bracket doesn't look that beefy though, but I have no idea how beefy it actually needs to be. Matt states that he used the kit for a year of heavy usage, before making it available, so it seems he did his homework. If I didn't already have my 350z track rotor BBK, I'd definitely consider it. The price also seems quite reasonable. My Stoptech 2 piece rotors alone were over $500.
