New IRS Design....

[KevinVarnes]

...for Fox body Mustangs of course. We can't get somebody to even make a set of halfway decent front shocks for our cars and they've got (potentially multiple) companies designing and selling complete IRS conversion kits.

New IRS for Fox Body Fords Makes Corner Carving Less Taxing - Hagerty Media

Tired of being stuck with stick axles or used Cobra parts? RideTech now offers a Fox Mustang independent rear suspension.

Unfortunately it’s all about market demand. There are so few of us who maintain, let alone mod these cars anymore. The demand for parts just isn’t there.

I’d rather have a live axle conversion, personally

Couldn't agree more. There's a beauty to the simplicity. On the other hand, I love how my car handles even at 28 years old.

There are so few of us

Amen.

I had to laugh. I was just poking around on craigslist after reading some of the posts here and found this:

Would the Mark IRS fit a T-Bird/ Cougar?

Then I found this:

And wondered if the engine and tranny would fit in my 94 Cougar... sounds like a headache before a vision.

Been there, done that ... two times. And yes its a lot of work.

Yeah, I'm fully aware. It just annoys me that we are scrounging around for any junk that is remotely close to fitting our cars just to keep them on the road and these guys have a brand new $8k IRS that they can just bolt in.

At least Ford is remaking the PI intakes for us now though!!

Mark VIII IRS is a direct bolt in, but other than the aluminum (open) diff and aluminum lower control arms it is identical to what you already have (unless you have rear drums).

Drums? In the REAR? NEVER!!!!

Yeah it’s much easier to just “convert” the stock rear into mark

I’ll obligatorily show mine off too lol

Ignore the dirt and leaves .. I havent touched this car since 2010.

Anyone have a guess on weight drum vs disk?

It’s been a minute since I saw the drum setup, I forgot how giant they look in relation to the spindles

 

[Fred Smailes]

I've wanted to complete the 3.8SC swap with the rear suspension but want to maintain present wheels,, look. Problem is overall IRS width needs to be about 16" narrower than stock which means the CV boots would be contacting each other,,! Plus travel would be reduced to 6-7" and frame rails need to be moved inboard.
Problems, problems,,,

Snazzy blender you have in the trunk, will you be adding an ice-maker, too? I assume that's what that white mounting bracket on the right is for. Big hit at tailgate parties.

 

[Rodeo Joe]

I think that's a light.

Dang, I want a nice exhaust under my Cougar! I ordered OEM mufflers for my car that were supposed to fit the 4.6l dual exhaust and got the size of 3.0 bore (well, larger than OEM pipe). I had to manufacture reduction pieces to get the mufflers to fit the exhaust pipe.
Nice pipes 97!

What rear end does the LSC have? I've considered a full swap since I've got rear drums, but I also have the 8.8 3.27 limited slip and I'm not giving that up for anything. I'm assuming I could just swap my pumpkin over to a Lincoln assembly if needed.

Yes, you can swap your pumpkin over.

It's a lantern I bought years ago for catfishing at night and later discovered it's great for working on about anything

Mark diffs are all 3.27\, one legs

 

[Rodeo Joe]

I thought some had the 3.08s also?

Joe

 

[MadMikeyL]

The standard MarkVIII had 3.07 gears (yes, 3.07 not 3.08, no idea why they bothered making 2 different ratios that close together). The LSCs got 3.27s. All of them had the aluminum housing, and all were open diffs.
