Here are some progress pictures of the Viper differential assembled with narrowed Corvette style rear suspension in the stainless steel chassis. The half shafts, tie rods, and camber bars are fabricated new. The half shafts are aluminum, the tie rods aluminum with stainless heims, and the camber bars stainless tubing with stainless heims.

We should be assembling the rear knuckles and spindles shortly. Trusting that it should work out to a 58 inch wheel mounting face width.

Gene, that's pretty darn cool!

I had a few questions for you out of curiosity.....will the Viper Dana 44 accept the Corvette Dana 44 side yokes? I thought the Viper setup was different with a slip yoke and CV joints. Are you using the Corvette "dogbones"? How did you account for the toe adjuster plate thickness in the differential? Are you going with coilovers or air ride?

Nice work!

I think perhaps through 2001 the Viper had similar side yokes. In 2002 or 2003 they went to constant velocity joints.

I've already polished the dog bones, so I'll probably use them.

In accounting of the toe adjustor plate, do you mean the orginal Corvette toe adjustor plate, or the one we fabricated? The fabricated one is more in line with the actual mounting at the knuckle. Should have less bump steer due to location and assigned pivot point.

I have purchased some coil overs, but am considering some factory style air suspension units rather than aftermarket. How compliant are the aftermarket units? The few I've ridden in are extremely stiff, they may not have been set up properly.

We had a Lincoln Mark in the 80's with air suspension that rode better than the recent model Lexus (should note this one didn't have air suspension, though available).

I see that the plate is sandwiched between the differential housing and the batwing. I thought the batwing had some sort of bearing supports in it, and by spacing it back you defeated those. Are they there in the Viper version?

You are indeed correct that the Viper rear differential cover has bearing block supports for the carrier. However, in spacing it (the cover) back, we did not defeat the supports, but maintained them by sustaining them. Good question.

Gene nice work, everybody likes shiny stuff, but obviously you've put more into it than just shiny.

Gene, did you end up making any geometry adjustments with the lower strut rod to account for narrowing the suspension? Sounds like you lost about 5 1/2" in width.

Yes. The strut rod inboard pivot was lowered and moved forward. Decreasing those two angles after moving the knuckle inward.

Lost approx. 4-1/2" from the early C4 model wheel mounting width.

The assembly is progressing farther. Here are some photos of the rear knuckles, C5 brake adapters, Porsche Turbo rotors, assembled to the camber bars, 4 link, and half shafts.

I always thought that rotors needed to be installed so that the cooling fins faced forward to catch air. Am I misinformed, or is that designed that way for a reason?

Gene, that sure is looking "sick". Coupla more questions....why the Porsche rotors? Wouldn't Wilwood or Baer do the job and be less expensive? What are you planning to do for an e-brake?

John, the rotors are designed to pull air from the center and throw it out toward the wheel for cooling. Mine are installed the way Baer labeled them and they're that way:
