Yes, the calipers are similar, but not the same, IIRC. Making adapters for the later uprights would make the most sense. Bolt-in bearings, better ball-joint geometry, and the adapter for the brakes bolts on. There WAS a big brake kit for R/T's that used the Neon SRT-4 Willwood front parts, but I don't know that more than 1 or 2 was ever made. I want 13" rotors anyway...
