IRS?

[Grand Marquis GT]

Alright, I know when I had my turd, the IRS was pretty good.

I was wondering, could I modify one of these to fit my box? I know this would probably make a difference in handling, bigtime...

I can't remember the width of them both drum to drum, but of course I know scott has one of each car so that wouldnt be a problem

I know it would require some fabrication, but what doesnt?

[seneeb]

look at newer explorers for components, that would probably be the best bet.

or an expidition

I wouldnt suggest LS. 1 it would be too narrow, 2 the suspension componentry is built for a much smaller vehicle

Stay away from the MN 12 IRS it is not the best donor. try to find one from an 99+ Cobra, alot of guys swap to straight axle and sell them for around $500. The rear suspension will bolt into a fox so you will have to make new mounting brackets. also might have to run a wheel with more dish than normal, im not sure on the flange to flange distance compared to our cars.

Mustang road race guys say that a properly set up Three-link handles just like an IRS car.

From what I've read, the staright axle is much better. The IRS has alot of brake/acceleration steer from the bushings and design compromises.

Im sure most of that could be cured with Maximum Motorsports "Grip in a Box" although the kit is not cheap, IIRC $500+

Mustang WMS is roughly 5" shorter than Panther, which could be compensated with deep wheels.

I think IRS would be great, you will have to make a lot stronger anti-sway bar. And the frame will need some stiffening I think as well.

[Grand Marquis GT]

If the benefits outweigh the cons, I think it would be cool.

I plan on running pretty wide wheels in teh rear anyways... some 17X9 wheels widened to 17X11 or 12... I think some rear framerail werk is going to be needed as well...

[Blaze86Vic]

To run the 12 you will need to notch the frame out for it.

[Freshmeat]

Measure 2.5" in from the back edge of your rear drums and that'll tell you. The calipers may even stick another .5" past the backing plate, though. I think it'd be cool.

I know the IRS is becoming more and more popular among the local Fox crowd. One guy bought the IRS from a new Cobra and as it turns out, it's damn near a direct bolt-on. Slight performance loss at the track, but he says it rides like nothing else.

[Grand Marquis GT]

I ain't going to be drag racing it. It's going to be built for teh corners...

[Freshmeat]

Then definitely, yes. That's why this guy did it to begin with, for the handling.

[Grand Marquis GT]

Combine this with a bit of a weight loss....

[Freshmeat]

How? I'm pretty sure the IRS is heavier... lots of extra joints and such...

[Grand Marquis GT]

I mean putting the car on a diet.

Of course, with the motor and IRS stuff, after some weight loss in the chassis, it will probably weigh just as much as it does now...
