IRS Swap

So i was thinking of doing a IRS swap into my 01 GT i was wondering if there's a write up on it and if its really worth the work and money? Thanks everyone!

Everything bolts right up, only decision is whether to change the u joint on the driveshaft or the pinion flange on the diff.

You will need the irs assembly with all hardware and brackets. Irs springs and shocks.

Stock for stock, can an IRS hook up better than the 8.8 SRA?

As far as drag racing? The halfshafts is the weakness, they don't take much of a launch to break

I've seen a few IRS swaps on Mach 1's. I'm wondering why. I think the Mach's were kinda setup to run the quarter more so the GT's. Maybe it's Cobra envy, Lol.

Are they worth the swap and time and money? Do they handle better? I don't plan on drag racing more autocross style racing.

Well, you will be adding right at 300lbs to your car and honestly a sra can handle better than ford's version of irs. If I was building a irs car to be competitive it would involve $1800 in mods just to start. That's why I went with a built sra in my cobra

Do you think an aftermarket option would have a less weight increase compared to the Ford IRS too?

There are no aftermarket irs units currently on the market I know of. The problem with the factory unit is ford designed the irs unit around the sra format. It bolts to the lca and quad shock locations.

Wow, when you mentioned that it bolted right up, I assumed there were holes made during manufacturing that ended up on all uni-body stangs to save tooling, etc. They really did slap that in there.

Yupp. There is a bracket that attaches to three holes on each side where quad shock attaches, I believe only two of these are used with the quad shock setup.

I swapped a sra with a irs in under 30 minutes with hand tools, it's really not hard.

What is your car and what is currently done to it?
Also, what are your goals for the car?

You should always when running boost, the stock crank is good up to 600 hp, I would just to be safe but how much boost do you plan on running?
