Just a ride, but interesting.

For those who think the IRS is just for a cushy pansy-azz ride:
In other words, despite the 2014 GT500 having a towering 224hp more, and a boatload of extra torques too, the IRS 2015 GT was able to stack on an whopping 20mph(!) over the GT500 on the back straight.

 

Because of traction issues. Not IRS v SRA.

 

Lmao^^ here we go

 

I have one thing for you to watch... IRS well Just watch. Next time they will have compare 2 same cars one with IRS and the other with LS..

I'll Take LA:

 

Ha, ha, ha. The guy sure loves his SRA. Does not want hear about any flaws.

 

It is a fair point, nothing more.

Unless the car is otherwise the same and a capable SRA and IRS setup can be had (without adding extra weight, like a Fox body IRS setup, 'cause that'd just irritate someone, right?) there can never really be a good answer. Heck, it might even need to be the *same car* except the rear suspension and driveshaft.

IRS is best for slaloms and twisties.

SRA is awesome for drag racing and straight lines.

Who wins? Whatever works. Someone wants and SRA in there it'll get put in. That's a big mod, but watch. *It'll happen*.

/And front wheel drive is best for snow and uphill, both ways, get off my lawn.

 

Tru'dat and as always location, location, location!!!!


Here on the east coast (especially the lower mid-atlantic) the roads are smooth, straight and speed enforcement is thick so drag racing is king and the SRA has a good following.

 

He hears IRS and thinks the gumbmint is after his money.

 

I just hate the IRS

 

Caused by, you guessed it, the Jitterbugging lively axle of the GT500:

"...the GT500 suffered from extensive wheel hop, significantly slowing the car down."

Something the IRS 2015 apparently wasn't beleaguered or slowed down by. Hard to get much traction when your wheels are in the air half the time.

 

I hate disk brakes, coil springs, radial tires and all those other modern sissifications slowing our cars down.

 

It will be interesting when someone can compare a 2104 to a 2015 on the same day, on the same track, comparing base to base and Track Pack to Track Pack (or Performance Pack or whatever it's called now). We know that the 2015 with Track Pack is supposed to be faster then the Boss 302, but I'm interested in how the non-TP GT stacks up.

 

What I am expecting is that if the 2015 performance pack can out run a boss 302 then the 2015 base gt suspension should outrun a 2014 track pack.

 

I've been reading this forum for a while now, and it is clear some folks think technology is a savior, and others a demon.

I'd like to ask the IRS folks using name calling and sarcasm: Have you ever driven a well set up SRA car on a track or does all your knowledge of the pros and cons get spoon fed to you by magazine writers?

Here's what I see, a bunch of people that expect IRS to fix their bad driving. This is Corvette mentality. Spend more on tech and be a better driver..

Is IRS, when done well, very drivable and fast? Yes, absolutely.. Is it the answer to all a drivers prayers? Well, I'm sure Steeda, Roush, etc will have lots of room to improve on what rolls off the assembly line and the track will still be clogged with bad drivers in good cars...

Parts of me mourns the loss of the 8.8, and tries to anticipate how much upgrade parts are going to be for the new diff, parts will like the improvement on the trash they call roads in most of the US..

 

Check out Lethal Performance. They're already working on IRS components, axlebacks and supercharger kits.

 

I have full Kenny Brown Panhard bar road race suspension with 5-way Tokico's and I have noticed a big difference in handling. My lap times at Barber's Motorsport Park were within a few seconds of the Mustang Challenge Race Cars!

I will have a 2015+ in the stable someday!!

 

Have you driven a well tuned IRS suspension on a track and/or on your favorite public mountain road?

One of the the things that bothers me a little is that many if us that are not intimidated by an IRS suspension have some experience driving both types, as does reviewers. So we have some bases to give an opinion one way or the other. However must people that are all about SRA have not. Muscle car and trucks is all they have been driving all of their lives thus I kind understand their strong bias towards SRA. However don't tell me IRS is a myth, problematic, doesn't improve anything when you have never experience driving one. That is just being ignorant.

 

Agreed. They've been using IRS in cars only maybe 20-30 years less than SRAs.

 

Torino you nailed it.!!

Most people on these and other forums are like lemmings. I don't mean that in a bad way just saying. They follow others well Because and they read magazines that say things that only support what they want to say or what the driver in the cars doing the article is use to. Most can not drive there cars with the HP they already have.

I will guarantee that my Suburban with a SRA and a race suspensions will take on a lot of sports cars and would leave your mouth hanging.

So both will be great but depends on how it is set up and if it works for the Driver.

 

Intimidated by IRS? A myth? While you are perceptive that I have some seat time in muscle cars, and a couple Lightnings, I actually am looking forward to an IRS Mustang, except for the additional costs. I'm just not snowed by reviewers who are paid to sensationalize, or ham hands who blame bad laps or getting passed solely on the axle. My own lightly tuned '12 GT does just fine street or track, thanks..

If you consider an Dinan e28, e39 or e60 M5, or a Competition package e92, well set up IRS cars, then yes, I have driven well set up IRS cars on the street and on the track. Driven some bad ones too, I had no love for any of the Challengers I tracked..

Reread my post. I ask a simple question, have the folks hailing IRS as a savior, and SRA as the enemy of performance, actually driven a well set up SRA car? One so far purports to, even going so far as using "we" and "us" to have perceived backup for their thoughts, but has not put forth any objectivity, just multiple assumptions.

Note, I did and do acknowledge that IRS has advantages, but I maintain my stance that it can't fix a bad driver, and isn't a requirement for a fast lap time.
