I'm pretty sure that the turbo rotors are thicker than the N/A rotors were so you would probably need a set of those to go with the calipers. I think they are thick by 2mm or 3mm but I'm not sure off the top of my head. When you said that you had the early arm in the rear did you mean that you have steel arms or the early aluminum trailing arms. Wait that doesn't matter since all of the rear brakes use the the same bolt spacing as the turbo calipers I think.

The rear should just be rotors, calipers, and I think a few washers to get proper alignment of the caliper on the rotor.

You will need another caliper adapter since the bolt spacing is different on the front turbo caliper compared to the N/A caliper.

Try a using the search function, the information has been covered before and the answers are there somewhere.
