His last line says it's a better idea. He was questioning the radius rod set up and the CCX design I believe. I made a fixture from a Watts in a CCX. I took the dimensions and put them into CAD and moved the suspension up and down and could not get it to work. This is an Acton Custom Watts and you see how well it works in the video.

azfordman What Mic Has redesigned may work very well. The problem is what are the limits of the setup. 10 years ago ONLY a few cars where making real 400 HP at the rear wheels. Today I have to include myself in this group. The vette people had the same rap up problem in the vettes. Gulstrand ( I have the name spelled wrong and can't find the article at this time) designed a 4 link with high low bars to the outter support housing. It kept the wheels in location but had a binding issue around turns at high "g". Wheel hop seams to be the biggest problem with cobras and IRS setups. Rick L. Ps the failures of the contemp system was the pivot bolt snapping off at the pivot arm and in the middle of an event at 100 mph in turns. All that was needed was a larger shoulder bolt or a high grade.

Rick the name is Guldstrand. Is this the setup you saw? This is designed for a C3.

Ralphy That's it. It does work very well. All new vettes used this basic setup for rearends. No pivot, just straight arms to the rearend. I know it changes the rear alignment a little but unless you are a PRO racer and driver you will never know. Rick L. Ps custom shocks where also used over the stock setup ones, Koni's.
