To answer firebird99, simply put it doesn't make its sound like a vette. The unique sound of a vette is due to the header shape, pipe routing, and crossover pipe (H or X) used in the line.

It's nice to see someone took the time to make a well thought out post with the pertinent info and all the links, there's a few there I hasn't seen before. As much as this topic comes up I'm surprised it's not made a sticky.
A job well done sir, thanks for your time.

Borrowed the neighbor's GoPro. Under car videos
For the sake of comparison here's a Ford S197 Mustang which, with its 3 link and panhard bar, has a rear suspension that is substantially similar to a 3rd/4th gen Camaro or Firebird (which has a torque arm for it's third link).

I'll say this too, Jay Cutshaw was instrumental in getting this project done. Input from Orange_99_SS, Wilson Muscle Cars, and 1MeanZ was also used. I spent eight years researching this, and I'm glad Jay went first.
If you can't weld, get Jay's shop to install it.

It doesn't squeak or rattle, except for the driver's side bump stop which I made too long (the bump stops are on the shock shafts). I'll fix that this weekend.

I want to preface this by saying you could do it for a lot less, I powder coated everything, replaced everything that was worn, bought a Dana 44 (as opposed to the Dana 36) and had it rebuilt. I also had the wheels rehooped instead of using adapters, and bought Koni DA's and had them revalved by True Choice.

Lee, just so you know, Jay finally joing LS1tech and that's him...banshe5. haha
I just got off the phone with him and he told me to check this thread out. I was like a kid watching that video. I'm a mechanical engineering student myself and I love watching all of the suspension dynamics and articulations. I must say Jay's car is a dream to drive and such a wonder in the corners. I'm glad you've made this thread and hope at some point it can be stickied for anyone that has questions.

I originally planned a much bigger thread with a lot more pictures, but 1meanz stole that thunder with his GMHTP article, and his thread on thirdgen.org, so I just linked to his.
Orange_99_SS helped me with this thread.

A Watt's link only allows for a solid axle to perform in a way it never has. Watt's will never be able to perform like IRS's, but it would be interesting to see how close it is in comparison with the standard solid axle suspension with the trailing arms being relocated.
