The main limiting characteristic of a RWD live axle like the Stang's SRA isn't so much the "beam" aspect of it but rather, the massive unsprung weight of the heavy duty drivetrain elements of a high-torque V8 contained within that "beam" in a RWD car. Perhaps if Ford could figure out a way to make the SRA ought of aluminum, magnesium, carbon fiber and titanium and cut the unsprung weight in half, then this whole discussion might well change. But then, all the high tech stuff with its commensurate high price tag would make an IRS a far more affordable approach to handling excellence.
Or perhaps that best/worst(?) of both worlds, the DeDion suspension?

The funny thing is everyone considers price to be the main issue here, I know i've said it before but Dodge's base V8 Challenger comes with an IRS for under $30,000. Lets also not forget that it was Ford who actually first started putting an IRS in the Mustang back in 99'. The Cobra in both 99' and 01' sported an IRS and were in about the same price range as an SS Camaro with a SRA. According to my research the bump in price for an IRS equipped Cobra in 99' over the SRA 98' was just $1760. Lets not forget that the 99' also had more power, and improved suspension and at the time all new styling.
Force Ford to include IRS and push up the price of the Mustang in today's current market and we could be looking at the end of the Mustang if sales numbers drop. The IRS may appeal to those Euro lovers brainwashed by the media that IRS is the end all for performance but if the price forces the "secretary" buying pool to switch to a "Nisyota" then what?

my 07 was under 30 with premium package, heated seats, alarm, sirius, 3.55, power passenger/driver, side air bags. if it had 18s it still would have been under 30. thats sticker, not what i paid.

Ok, still just talking price...what is the actual "about" starting price for a 2009 Mustang with a V-8 so we can compare it to the quoted base price of a V-8 Camaro (how many will actually sell for "about" $31,000)? How about the price of a Camaro as most performance enthusiasts would have it, that is with manual trans, limited slip rear, decent rear gears, normal creature comforts, etc? I don't see the Camaro price being in the ball park of a Mustang when those things are considered. Just like with the Challenger as I described previously.
Is a cheap, poorly designed IRS system better than the Mustang's current SRA (Ford doesn't have the cash flow to spend a whole lotta dough on it right now)? If a decently designed SRA can perform nearly as well as a car with IRS, what is the point of making the change for FORD if the car with the SRA still sells? Ford is not in the habbit of making "Enthusiast" cars within a decent price range. Model for the masses goes back to the Model-T.

Look what BMW has done over the years. For generations they were "underpowered" compared to the competition, yet have long been the standard for ride and handling due to the emphasis on developing the suspensions. They have only recently begun adding hp to cars that were already superior to everything else in their class, even with less power. Killer combo, handling + hp...

Yes, yes, yes, Ford is NOT BMW. The Mustang is not a Cobalt SS (thank God!). Ford relies on selling "secretary" flavor Mustangs in order to keep the model alive for us enthusiasts, for which I am eternally grateful.
Nevertheless, there is a significant number of true Mustang enthusiasts that understand the benefits, even to those other Mustang owners and enthusiasts who do not know or understand the differences, to having a well-sorted IRS in a performance vehicle. Maybe in the base V6 an SRA would be fine (for the "secretaries"); and a stout SRA available in a V8 performance package for the straight-line folks; with the IRS in the GT & mid-level SE's? The cost-conscious could buy at the lower end and be satisfied; the drag racers who generally spend money for add-ons anyway can have the SRA they want; and those of us who enjoy driving less-than-straight roads (not Kamikaze; at safe speeds), or who commonly drive on crappy pavement (I do both) can have the handling/ride benefits of IRS
But cost shouldn't be that big an issue. IIRC, the original IRS designed for the '05 was supposed to up the production cost less than $200 per vehicle. If that is true, then the cost/benefit ratio there should be more than acceptable, especially compared to some of the other options Ford has offered and is about to offer.
If on the other hand IRS raises the cost by an order of magnitude over that, say roughly $2000, then I quite understand why Ford is NOT offering it, at least not yet. And even if they did offer it on an SE, it would likely be out of my price range.
So I'll continue to drive a SRA Mustang because I am a Mustang enthusiast. I don't want a Camaro, Challenger, G35, 335i, M3, Cobalt SS or whatever else comes down the pike. I just want the best Mustang I can get my hands on. For me, that would include IRS.
I recognize that IRS is not for everyone, though, and for those that are happy with the SRA, good on ya. I'm happy that folks are happy with their Mustangs in any flavor, and happy that Ford has made it such a flexible vehicle that it offers so much appeal to such a broad spectrum of folks.
But for me, and at least a few others, IRS (at a reasonable price) would be a significant improvement. And I will continue to lobby Ford that one day it may come to be...

Yes, an independent rear suspension would be nice to have, and if it was offered as an option I'd likely buy it. All the elightened, sophisticated "true enthusiast" bench racers make it seem like the lack of it in a Mustang is this HUGE crippling flaw, when it's not.
I've got a 240z with IRS, and quite frankly, my S197 rides & handles just as well, maybe even better. Not bad for a car that weighs a thousand pounds more and has twice the passenger capacity.

If you guys wanna use that strategy the 05-06' GTO at rebate was selling for less than a comparably priced Mustang GT. The GTO had 100 more HP, 6 speed, IRS and was a better flat out performance car stock for stock.
Yes, the car still sells but bonehead moves like letting yourself get spanked by the competition may remove them from that spot.
The base V8 Camaro comes with all the basic creature comforts, you don't need 20s, leather and a 1000 watt sound system.... I personally don't care what Ford's financial status is. Last I checked GM is in the same boat yet they are continuing to deliver one great Performance ride after another (Z06, ZR1, G8, CTS-V, Cobalt SS etc....)
How do you know that GM's IRS system is cheap and poorly designed? Last I checked GM has been making 500-600HP Corvettes with them.... Wait a minute isn't the four door full size sedan CTS-V a better overall performer than the GT500? Just wait until the first comparison tests of the SS Camaro vs 10' GT. It is going to mop the floor with the GT. If we are going to have the Bullitt suspension as rumored, I'll bet on it.
And again stop using cost as an excuse. Ford was the first of the big three to offer an IRS on it's Cobra model from 99-04. Keep this in mind the difference in price between the last SRA Cobra of 1998 compared to the all new 99' Cobra was just $1760. Remember that the 99' Cobra was a brand new restyle that offered a host of improvements including more power, revised suspension and just more overall content.
I'm not sticking up for GM by any means, but I sure will defend my valid arguments.

I don't understand why people are against progress in terms of Mustang technology. A SRA is a dated technology and inferior to an IRS rear. Ford needs to embrace change and take some risks instead of being bull-headed and slow to react. Ford's current business model isn't working.
I think it would be great if Ford showcased some modern technology in the Mustang. The new 5.0 is a start, but how about direct injection, a Dual Clutch Transmission, and a modern suspension? Ford needs to start planning for the future!
