Alright I know this might seem counterintuitive, but I'm really curious if its possible to swap a C5 IRS rearend into a 4th Gen F-body. I know in doing so you'd be giving up a bit at the drag strip, but I think it would be great in AutoX and open track racing. The big question though, is it even possible or would it require such significant modification that it wouldn't be worth it.

Thoughts?

Youd probably have to cut so much of the car out and fabricate so much that it wouldnt be worth it; unless you were doing it on a reality TV car show.

But to be serious, for that much money the gain in performance wont be much better than a well suspended live axle, IMO

It can be done. I`ve never seen one in a late model f-body. I know several people have done them in first gen f-bodys though. I can tell you though, it wouldn`t be cheap. Doing it yourself would be at $5000 with parts and that`s just a ballpark figure. Paying someone else, then the sky is the limit. That is something that can be screwed up quickly if not properly installed, so you have to be careful. I know the late model and the first gens are similar underneath. I haven`t ever really tried to compare the 2 or make any measurements though. I have both late model and firstgen f-bodys and I am very familiar with the first gens. I`m relatively new to the late models. There is a guy that builds kits to install them into firstgens. His name is Wayne Due. He is widely known in the first gen world. He has a website so you can just google Wayne Due and find his site. I personally wouldn`t go that route with a corvette rear suspension though. If I were looking to put in a different type of rear suspension, then I would go the 3-Link route. A 3-link would handle perfectly on the street, dragstrip or in autocross. All you have to do is make a few adjustments for the type of driving you`ll be doing to make it work in any of those scenarios.

Hmm, me and a buddy put a Dana44 IRS from a '91 Vette in his 3rd gen for...well, cost of rear end. Whole thing including material to make a new torque arm was under $1000.

It's not a bolt-in, but it definitely can be done.
