C4 IRS measurements in a 69 Camaro

[lbdz28]

I am in the process of putting a C4 IRS in a 69 Camaro and would be interested in any comments about what I have come up with for the placement of the rear end and wheels. Right now the rear end is held in place by a series of C-clamps, jack stands, and brackets so before I fire up the welder I would really appreciate any information you could provide. I have placed a longer then normal bolt in the transverse spring to place some load on the wheels and hopefully hold them in their correct location. Here is what I have for measurements:
Measuring down from the top of the wheel well lip to the center of the wheel it is 13 inches. I am thinking this would be normal ride height.
Measuring horizontally the center of the wheel is forward in the wheel well about a half inch from center.
The half shafts slope down and back from the center about 2 degrees.
The pinion is pointing up 3 degrees. This places the nose of the center section almost against the floor boards right at the start of the tunnel.
My biggest question is with the four links. I am thinking they will be placed so at normal ride height the top bar will be almost flat (parallel with the ground), but will be slightly sloping up going forward.
Again any suggestions you can provide would be most appreciated before I do something I live to regret.

You might want to try Performance Trends Suspension Analyzer. It can help you with the pick up points your looking for. They have an example file with all the stock points for a C5 vette. Just google it and you should have no problem finding it.

Wayne's kit required a lot of cutting and welding. It wasn't "bolt-on" in any way.

I tried the suspension analyzer and while I got lost pretty quick I couldn't see how to get the answers I needed. I was hoping that someone that has already done this could say if I am headed in the right direction or not.
I will try getting ahold of Wayne but I have heard he is hard to track down these days.
Also not sure how helpful he will be as my car is highly modified already and I couldn't use his kit.

Call this guy:

Jesse Lombard
(425)737-4089

He use to work for Wayne. I think he had the jigs for some of Waynes stuff too. Wayne also told me that if Jesse needs any help he would lend a hand.

Good Luck!

...I would remove the spring from the equation at point of mock up. If it is not right it will throw the whole deal off if full weight isn't archived.

send me an email and i''l try to help you out. [email protected]

Mr. Quick gave me some good information and some great pics. Back to measuring and adjusting. Thanks for the help.

Hey Larry, would you share the pics & information? I have an early 90's Dana 44 Vette rear that I want to put in an 86 Monte SS.
Thanks,
