Ive got a lead on a '96 6 speed parts car that I was hoping to grab the rear suspension out of... IIRC someone mentioned that the early C4 stuff is easier to graft in than the later? If so, what hurdles will I need to overcome to use this suspension? Id like to use this one because its cheap, local, and a D44 (which is usually not cheap!)
Don't know if I'm that someone, but I have made comments about putting a C4 suspension in a C3. In my case it was noticeably easier packaging an early C4 rear suspension (compared to a later C4) due to my self imposed restriction of retaining the stock C3 trackwidth. If you retain the C4 trackwidth then any C4 rear suspension packages pretty much the same.
When I narrowed the C4 suspension I used '84 knuckles as they are about IIRC an inch narrower. This helped me to not have to cut the frame and bodywork area directly above the halfshafts for clearance during bumps/jounce. Also IIRC the later C4 calipers are wider (thicker) in the inner side, which would have hit the bodywork on my narrowed suspension worse than the early calipers. (I ended up using non floating Wilwood calipers for better packaging anyway.)
I kept the stock C3 differential because I had several different ratio spares sitting on the shelf, and I was always unsure if a C4 D44 might require fiberglass work in the tunnel area.
