Hey guys, i have the opportunity to get a front brake setup from a 02 a6 4.2 off a guy from craigslist for 100$. I've done a lot of research and i can't find a definite answer to whether or not the calipers will bolt up to a4 1.8t, iv'e checked on ecs and it says for the c5 a6 4.2 the rotors are 321mm so im thinking the calipers are hp2's(which i know bolt up) but iv'e heard that they don't come with those until 04 so if they're not will the old version still bolt up?
