All I can see is that people won't have the SRA scapegoat for their own ****ty driving anymore.

 

BINGO!!!

 

I have koni yellow's 1 turn from full soft / steeda sport springs / j&m cc plats/ steeda rear ph bar on my 14 gt. I think my gt will out handle any irs car ive ever owned. Does a full coilover 2011 Si count as an irs car, even though its fwd lol? I dont understand all the lra hate, especially in a Mustang forum. The S550 will be great and i hope i can land myself in the new GT350 in a few years.

 

People who hate the IRS likely fear that their current cars (to which many of us are loyal) are about to me made to feel very antiquated and inferior.

Personally, I want the new car to be as great as it can possibly be, regardless of what I drive. I have little doubt that it will make our beloved S197s look like garbage on the backroads or a road course.

 

What I don't get is all the apples to oranges comparisons. Every variable is important. Can a pro in live axel out run an amateur in IRS? Of course. The question is, comparing two equivalent cars, which one will a particular driver prefer? I don't know of any pro (whose livelihood depends on it) that isn't looking for every advantage they can afford, to improve their times. For enthusiasts, they will spend what they can afford, to maximize their driving experience. My bet is IRS is one of those no-brainers for the vast, vast majority of sporty-car buyers - apples to apples.

 

I will now post a comment equally unrelated to any post in this thread:
"People who love lemons think limes are jealous"

No one, besides the first person to roll a vw beetle over, hates IRS. And certainly no one on this post. It's just not a cure all, and it's costly to upgrade when there's not much scale like the 8.8 enjoyed. (Even the 1999-2004 IRS shared some diff parts with the rest of the herd)

See my points above, feel free to argue them, or accuse chestnuts of being lazy. Your choice.

 

Hah, no technology is foolproof for no sooner does someone come up with a better foolproof technology than someone comes up with a better fool! The IRS might though do a bit better job of saving the bad driver from him/herself even if its no shield of invincibility. More importantly, it should make any driver's performance that much better due to its overall greater capabilities.

Again though, the proof will be in the pudding once these things finally hit the streets and (test) tracks.

 

No rhumb - you're wrong on this point. It was because of the extra 200+ hp. Which has always challenged the GT500.

Add 200+ hp to the '15 GT with its IRS setup and then you'll see some real jitterbugging wheel hop.

 

But the current car suffers from wheel hop even with the standard V8 engine.

 

It also sounds like the GT500 needs a driver mod, from the description in the article.

 

All good points but there's a reason most all sports cars, especially the ones running on road courses, went away from SRA's in the 1950's and went to fully independent suspensions - the Mercedes SL being one of the first - and there's a reason the only SRA cars built in the past ten years are Mustangs and Panther-platform cars. IRS is inherently better for more situations, on track and off, and disputing that is akin to telling EVERY car company on Earth they've been doing it wrong for decades. Yes, Ford and tuners have made the Mustang's SRA work far better than it should but that doesn't mean it's better.

 

Who exactly are you trying to convince that IRS, done well, is a good setup? The guy who has said a couple times that, done well, it's a good setup? By the way, any history lesson should include all the terrible IRS attempts early on just so manufacturers could say, "look, I have IRS"...

My point, starving for argument, was, is, and will remain, that despite what magazine writers and keyboard racers will tell you, the 2014 and older stangs aren't useless antiques, and IRS does not equal speed, nor is it necessary to go fast.

Enjoy the S550, it will be smoother and more refined, faster stock for stock on a track in equal hands. I know I will, if ford really gives the gt350 enough attention to not be a paper tiger. Anything slower than z/28 laps at the ring are a fail.

Just get ready for two things
1) parts will cost more
2) a good driver with an antique will still pass an average driver in the S550 and a whole new pile of excuses will crop up..

 

How much do you want to bet that we'll hear about a rash of broken axles for early adopters who run slicks?

Like many drivetrain components that we have seen on these cars in recent years, they're designed to handle stock power on street tires...nothing more.

I bet they're already working on a revised part number for the 2016 model year.

Sorry to be cynical but we saw this with the Camaro and it seems like one of those problems that is nearly inevitable.

 

My 2012 GT had Steeda Ultralite springs/HD shock mounts, Koni shocks, J & M panhard bar, Eibach F/R 3-way adjustable sway bars. 18x9/10 wheels with 255/45F/285/40R Continental DW tires. My new STOCK 2015 GT Premium, auto, 20"wheels and terrible Pirelli tires, 3.55 grears...and it handles better than my 2012. I'm convinced.

 

Unfortunately you have a very good point. There will be a steep learning curve with new technology. Bama/ AM already ran into this problem. Titanium half shaft upgrade should be offered by Ford Racing in the near future. It will all get resolved eventually, and the mustang will have a good IRS setup at some point.

I love to take my LRA car to road courses. My Mustang can take on much more expensive IRS cars, and beat them too. I have to work harder at it, but it is possible. It takes more skill to drive these cars fast. The IRS is the only feature on the 2015 I wish I had though.
