1968 firebird IRS kit
 

Hey all,
Nice place you have here. Like I have read in several post on this site I too have been searching for the ever elusive IRS install kits that don't cost 4500 dollars. So far I have been coming up short and hope you all can point me in the right direction. Even if i could just get the fabrication measurments / instructions to build my own...honestly as a matter of pride I would prefer this method.

Anyway...I would be greatful for any help I can get.

Thanks!:thumbsup:

I'm hunting for a supplier builder that does IRS stuff - will post it as soon as I come up with it.

In the meantime -- here's a handy dandy DIY bracket supplier you might find handy for many things while you're fabricating.

These guys have "kits" for Corvette IRS installs...

The prices you're quoting - 4K - etc -- would include the rear suspension... apparently you don't need those parts - you're just looking for brackets and instructions... ??

So try these guys:

Hey thanks for the response:

The cheapest quote I have had for the brackets alone (Ron Wilson) was 925.00 plus shipping. Still pretty steep for what it is! I have the tools to fab...I would really like the knowledge in order to do it myself. That being said I saw someone on here built one for like 425.00...I would forgo doing it myself for a deal like that...ha.

I may just have to take 10ccs of SIU and finger it out freestyle.

Thanks for the weldseries link, this will definelty help.

I built my own for my 67 Camaro. Really wasn't too hard to do. Here's a pic.

That is just what the doctor ordered! I was wondering what to do about the forward links as most setups cut open the back seat...now i know. Other than just running them forward and apart does the location of those links hurt performance or are they just there to hold things put?

Thanks very much.

I made mine adustable so that I could move them around if I raise or lower the car. It also has some effect on anti squat but I havn't tested anything yet. you can see that I made mine from Speedway products tie rods and qa1 endlinks so I can also adjust the kingpin angle on the rear (if it really matters). Mine are also longer than stock. I do have minitubs installed, with out those you would be inside the inner fender. If it helps you I have the .dxf files for most of the components that I had my buddy waterjet for me. That should be worth at least a case of beer to you! :cheers:

I don't know what a .dxf file is but if your ever in the area I would be glad to buy you some beers.:captain:

FYI

They don't make them for camaros or firebirds because they are unibody, was the reply I got back from them.

Thanks again though

a .dxf is a cad drawing file that your local shop can use to CNC the parts out with a plasma or waterjet table.:thumbsup: Way better than the old tourch or cutoff wheel method.

Where's the area I got to get to for free beers? :cheers:
