Howdy Guys:
I'd like to get a little help for putting a C4 Dana 36/44 into a 1st gen Camaro.
For staters I have templates of and have fabricated the brackets offered by Wayne Due a few years ago. The problem I'm having is that using the brackets at the desired ride height (245/40/18 = ~ 25.7") and 1" vertical clearance to the fender leaves the half-shafts at -4 to -5 degees (angled up). The second problem is that even with a 5" backspace the rims/tires extend out past the fender. The width of the C4 IRS will force significant rim backspace and/or narrowing of the half-shafts in order to fit within the fenders. If you narrow the half-shafts and use the factory control arms ("dog-bones") you are limited by the frame rails. It looks like you can gain ~2" on each side. If you do this the camber and toe-in rods will also need to be modified.
Here's some specifc info. I'd like your thoughts on:
What is the optimum (factory?) angle for the half-shafts? I know 2-4 degrees is typical for driveshafts but I would think that negative (sloping up) not only looks bad but also is not optimal. Is 0 degrees what I should shoot for? Strikes me that ~2 degrees sloping down seems right?
What about half-shaft angle front-to-back? Are the half-shafts intended to be in the same plane (straight with each other up and down) or are they too angled?
What angle should the control arms be set at. It appears the lower control arm is set at ~15 degrees for the Corvette. Should this same angle be the target in a conversion?
Thanks in advance for your thoughts!
