Ahhh i hope you read this because I went ahead and purchased the 12.2 rotors, 4 piston calipers, braided lines, and some fantastic hardware. These brakes are a steal at 750 dollars and they never fade! thats right, i said never. Drilled and slotted rotors, two piece design, this is a beautiful kit and i have to say it is probably my favorite u/g. Ive been doing autox and the brakes are responsive, firm, and most of all they clamp down like you wouldnt believe. hope this helps with your decision. product is two thumbs up.
