What's the BFD with IRS?
This may be a bit of a non-issue. As others have stated, wait for the 2011 GT: MUCH nicer interior, sexier styling, more amenities...and most importantly, 400HP (which if history repeats itself can probably tuned to 425 HP). And while I doubt you will see IRS, the suspension setup is rumored to be patterned after the current Bullitt, which is pretty adept in the handling department.
Sure, IRS would be ideal, but by 2011 it may not be necessary to compete with or trump the Challenger/Camaro.

I will attest to 350Zs being harsh, and will also throw in the Charger having a really soft/squrimy rear-end, as well as the Watts link on the Parnelli Jones edition being the best handling/riding SRA Mustang ever. That car rode awesome and handled so neutral and flat. It was amazing. If Ford could offer the Watts link standard, or at least on the GT and GT500, the development for the IRS would be pointless. The Watts link is the best of both worlds. And Saleen and other manufacturers have already done the development. They just need to produce it on a wider scale. Problem solved...
Ford could easily build a watts link suspension for the Mustang!! They have been putting watts links in Crown Vics for years!!
They'd have to change it back...not saying it can't be done, but the effort/$$$ for the extra couple of years.... would the benefits offset the cost/weight/peformance?
I don't know, I didn't build the car.
Then again its easy for us to say 'coulda woulda shoulda'...and everyone knows how to make a magic car that can satisfy everyones budget and wishlist

Look for IRS in 2015. Meanwhile, they will just refine what they're using now.

So you're saying that Ford is much smarter than every other performance coupe manufacturer in the world?!
Ohhh-K.
There's a good reason no other performance car maker in the world uses an iron girder for a rear suspension.
Well, a lot of those competitors are squeezing more horsepower per liter and per cylinder out of their sixes than Ford gets from its V8. The 4.6L V8, while a great engine, is hardly pushing the boundaries of what's possible. The current 350Z is almost as fast as the Stang GT with two less normally aspirated cylinders. Meanwhile, the forthcoming 370Z is rumored to be offering a V8, while the Camaro will likely get a Z28 that will compete with the GT500. Dunno about the Challenger; don't think it will be long for this world in any form.

Also, thanks for proving my point with your second rebuttal to my post. You just said that comeptitors to the mustang don't all use v8's because they can do just as well with 6 and 4 cylinder engines. Most people would agree that a v8 in general is a better platform as far as performance is concerned. Yet not everyone goes tha route. Just like Ford doesn't use an IRS because the mustang has a similar handling threshold as their competition. What I mean by threshold, is it can handle around a track just as well with some simple modifications. Just like a 350z for example can compete with a GT down the 1/4 with a few modifications.

Ford would have a huge winner if they can implement those changes. I know that's why I went the BMW E46 M3 route back in 01 and 04. The 5.0L 4V is still not really pushing the envelope with only 400hp out of a 5.0L motor..that's 80hp per litre when BMW is getting 414hp out of a 4.0L V8.

I honestly think you are being wayyyyy too picky about this (just like every other guy advocating that the mustang sucks without IRS). Most people don't even know the horsepower there car puts out let alone what type of suspension they have. All they know is how it feels. I haven't noticed all these thing that you claim SRA does. I don't notice how it hops horribly over bad roads nor do I feel like I'm losing control when I do go over poor roads. Now without souding like a jerk, maybe you just need more experience driving so that you feel comfortable navigating over poor roads.
Because like I stated above, I do not notice any measurable difference between SRA and IRS on REAL LIFE ROADS. On top of the GTI that I used as a comparison to my mustang, I also had a 300zx and 240sx and neither felt any better than my GT. I could only imagine how much better the 05+ mustang is.
As for the Mustang comparing to the vette or M3, are you serious? Now I know your standards are way too high, especially when you consider what price the mustang goes for compared to the other two. Now the GT500kr on the other hand can at least compare to those two although I am not advocating that it would actually beat them.
We will have to see. The GT has a LOT of work to do in terms of performance. Here's why I think that. C&D just did their yearly test at VIR. It's a pretty good test at the same track, conditions, etc. Well in 2006, a Ford Mustang GT ran 3.20.9. The new Cobalt SS ran a 3.12.5. That's over 8 seconds faster PER lap. The Camaro SS should be about 1-2 seconds faster at VIR, given what the comparison of the Cobalt SS vs Camaro SS ring times. I know this isn't 100% scientific and this is my personal hunch, but that's nearly a to second difference at VIR comparing a 06' Mustang vs Camaro SS. Again, this is just an analysis of times we've seen.
Ok, now your not comparing apples to apples! Your comparing the 2008 E92 M3 4.0L V8 to a Mustang? One is a mid $60,000 car (and a SICK car), but still a mid $60,000 car, vs a car that can be bought for somewhere in the low $20,000 with incentives! Come on!! Of course the BMW engine is powerful for its size. It only revs to 8,000 rpms and is derived from their V10 F1 (and M5/M6) cars, but again, its a car that costs almost $70,000!! And I bet that a good portion of the price of the M3 goest towards the cost of the motor. When you get high end components and an F1 team to develop the basis for this motor, its easy to have it! But again, price comes in play on this comparo. I know for a fact that most of us on TMS couldn't afford a Mustang at that price.
I have owned 2 BMW E46 M3's and now a 08 328i 6spd sport package sedan along with a 997S. I would love to get a Mustang with it's updated interior and I feel sharper looks over the E92 with the right parts and Ford could probably do it for under $40k. It's just a wish..
I do realize when I made this post it was apples and oranges but with a 400hp 5.0L V8 already in the works how much more would it be for a proper IRS for a car it was already designed for. This is after all the original premise of the OP.

The current Bullitt will scoot to 60 in under 5 seconds with the right driver - and probably take your E46 M3 in the twisties, too. It's not JUST about numbers on paper, it's about how everything works together holistically.
For example, GM's LS engine in the Corvette is a pushrod, but it's also a world beater.
Academically, however, I do agree that 400 HP out of 5 liters isn't exactly pushing the boundaries of what's possible...but by the same token, it's likely to be more reliable than a Euro V8 that winds up over 7 grand. And I expect the 2011 GT will hit 60 in 4.6 seconds...plenty quick given its price point.

That was the point of my post...to get near M3 performance and sophistication at a cheaper price. A few corrections though...you can get a M3 now in the $55k range as long as you don't load the thing up, it revs to 8400rpm. However, all I'm asking is for Ford to up the ante a tad and give us a Mustang with near M3 qualities at a cheaper price.

Sorry Dave, but the reason most people buy a mustang is because its cheaper than other offerings out there. I'm NOT paying close to $40,000 for a mustang! If I had $40k to spend I could easily pony up another $15k for a M3 or just get a 135. Everyone here that wants IRS thinks that everyone drives on the roads like you do. I dont care if the IRS does drive better, the SRA is adequate for daily driving and ALL normal driving situations. If I need it to handle better than it does, I can modify it with either a Watts link or other aftermarket items. If it still doesnt handle good enough, I didnt buy the right car! Dont FORCE me to buy something I dont need because you want something to do a better job than what its designed to be. IMO, if you NEED the IRS, look at vehicles that have typically in the past come with them already. The mustang has always been a mass market vehicle and by putting in the IRS, I believe you will go too far up the ladder for a lot of people, whether they cant afford it or not. Nothing personal, just my rant.
I'm not sure about the other people here but I like in Massachusetts, right in the heart of New England (GO RED SOX). Unlike warmer parts of the country, we have poor, cracked up roads in much of the state. It is on these roads that everyday driving can be effected by a SRA. I feel i'm more qualified than some here because I own both an IRS and SRA equipped Mustangs. I can't even begin to describe who much better of a ride my 03' has in comparison to my 97'. I understand that the current 05-09 generation is a much better setup than my 97' but it still skips and hops over rough pavement. I think something like this could be a deal breaker for many considering the Mustang along with it's competition that does offer the IRS.
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.
I understand your viewpoint, but I have driven one of those GTOs many times. Working in the car business, I am able to drive pretty much whatever I want including the BMWs. Therefore, the wheelhop and ratcheting I felt when under full throttle shifts wasnt pretty with the IRS and no, I didnt notice enough of a difference to warrant the IRS. Same with C6s and C5s.
Why is this debate still going on! Make it stop! No ONE side is going to win. No matter what Ford does. Just be happy your driving a Mustang at all. Trust me, I can't wait to get home and even SEE one, much less drive one.

I'd love to substitute the words IRS and SRA for fuel injection and carburetor, and then see how this argument ended up. It's like arguing on behalf of leeches and bloodletting in a modern hospital.

What really annoys me about the SRA, more than anything else. Is that dreadful wheel hop whenever going over pavement bumps. Especially when your right in the middle of shifting gears.
At any rate: I wonder if upgrading to LCA relocation brackets, would at least reduce the amount of wheel hop.
