Hi Guys.
A good friend of mine has a 9 second C4.The car usually breaks a spindle every 5 or so passes.The car has been in storage for 5 years now and he wants to bring it back out.What is available for a strong rear end now?He wants to keep the independant suspension.
Thanks

One of our members here "rklessdriver" has successfully managed 1.24s/60ft using the Dana 44 IRS. He has a proven working theory of how to do this with IRS. I would suggest contacting him via PM or searching for some of his postings. I have found some of his relevant postings that may help out.

I got 32 spline stub axles from summers brothers

I would tell him to save the headache and do a solid swap and call it done!! The money he would get for the dana 44 would cover the price of a built rear end and the swap really does not look that bad. All personal preference though.

I am wondering if anyone has tried using custom cv axles in place of the half-shafts and stub axles? Or will it just not work?

I"m using a 9"ford rear build by Carolls rod and race craft of N.J.
and a 1.80 powerglide from coan with a stange drive shaft.

Dont bastardize the c4. keep the irs. make it work.

There are 8 second IRS c4's out there (youtube it)

You dont need to be faster than that.

agreed, but how many 8 second runs can you get on it ?

I have seen MANY 10 second Vette's break the Dana 44 regularly.
Meaning they get 40 - 80 runs and then at some point in the season the rear breaks.
