2013 GT500 @ Nurburgring
#101
Ford plans on selling Mustangs world wide, the next Mustang will have an IRS..would be utterly shocked if the next Mustang didn't have it. Wether the live axle handles as good or not is sometimes not the answer to the question, but marketing sure is. The fact the Mustang rightly or wrongly gets dogged for its log stick axle to me is mainly marketing, which is largely devoid of facts sometimes but can influence a buyer due to the lack of it.
BTW, did anyone watch the ZR1 on the Ring..awesome video. Also, it has an IRS. Ran a 7:19...with production tires.

Didn't do a dang thing. But it did introduce the weak link of half shafts that continue to break - whether racing or reports of the Chally and Camaro.
As for the street its just a matter of driver discipline and trusting your vehicle - knowing your vehicle and how it responds. From British open roadsters, to off road vehicles, to pushing my Bullitt, to hundreds of thousands of miles on commercial rigs (Super Duty's & bobtails), its all the same - whether pushing hard on 2 lane bumpy twisties, or uneven snowpacked roads that are washboarded from chained up rigs, the key is to continue to have positive throttle (that doesn't mean floored). At least neutral - but some throttle is better - which means braking ahead of entering the curve so you are under throttle and have the correct weight transfer. Whether there is a brief skip or not with SRA, it immediately grabs and continues your line if you have acceleration and weight transfer. And how much better with Track-Lock. All the moreseo on snow and ice. It simply becomes second nature where you don't even think about goosing the throttle and mildly correcting the wheel if necessary.
Whereas too many feel a dimple and let off or worse hit the brakes because they don't understand and they don't trust their vehicle. And even with IRS if they hit the brakes, say goodbye.
SRA handles just perfect for me - by experience - and I don't have the weak link of half shafts. IMO

I wonder if the rears are still single piston floating caliper? Somebody said sometime ago that Ford couldn't go to a twin piston and maintain its current style parking brake - I got a chance to look at the rear brakes on a Challenger and they do indeed have a a twin piston caliper with a parking brake that engages the caliper rather than utilizing a seperate drum style parking brake in the hub.

Not that I wouldn't slap a set on my ride if they made them in a size that would fit my car

Agreed, seemed like to much sound filtering through for a turbo car
ford works realy hard to mute the SC, dump that intake muffler and go to an open element filter and the SC starts to make itself known. Overdrive it and it shines through even more

Right.
Point is IRS is not the "magic handling cure-all" the mag rag hypsters and their minions make it out to be. There were a number of wipe outs caused when going over the curbs. Those wheels were still airborne and lost control. Nor did IRS help when the Audi went off the edge of the pavement and hit the wall.
Handling aside, adding the weak link of half shafts resulted in race day over for multiple teams.
IMO that's a wash between theoretical (handling) advantage and practical (weak link) disadvantage.
Ford has proven repeatedly that even with uneven surfaces, SRA traction can be maintained with proper suspension, weight transfer, tires - without problematic half shafts.

Yeah they should get rid of it and go to an SLA setup. Why didnt they think of that sooner....
Because I mean...the IRS in F1, GT1, ALMS, GP2, DTM are all useless because they spinout...

Yeah I'd bet money you're a "OMG I'm gonna wreck! My Mustang SRA twitched on a piece of gravel in the road!!" and hit the brakes type of guy. ![Nonono](https://themustangsource.com/forums/images/smilies/nonono.gif)
You can twist my comments all you want, but over the years I've had to avoid/drive around more of you talkers/magazine readers that can't drive than I can count. I'll wave as I go by you in the ditch/snow bank as you (falsely) blame it on your Mustang SRA.

Good job indeed by team corvette, although the ZR1 is shod with Michelin Sport Cup tires designed specifically for the vette. It certainly strains the definition of street tire, but hell how many ZR1s are daily drivers?

I looked for a set in my size for my 2011 M3 at 255/35/19 and 285/30/19s to no avail..

Pilot Sport Cup tires were offered as an option as a factory size R-comp, since none were available. With a treadwear rating of 80, and being downright scary in wet conditions, I don't think I'd be checking those unless I was buying a second set of ZR1 wheels. Not to mention the cost.

Now if the ZR1 depreciates really badly and people start scooping them up because its a frigg'n insane car for a good price and start driving them on a regular basis then all those Sport Cup fitted ZR1s will get a nasty rep (anybody remember the NSX/Yokohoma debacle).

I'm waiting to see if the PS SS gets some more sizes in as the year goes by otherwise I'm stuck at the PS2 or the plain old Pilot Sport (how old is that **** tire!)
I really like Michelin's product, nice and balanced is what I like to tell people. There are no shortage of cheaper tires that will generate bigger numbers, but I noticed in a comparo, the Michelin PS2 was mid point in the grip department and really good in the wet yet offered the best control, communicated well and could recover pretty good.
The latter may not mean much if you go by the thinking that more grip means you wont have to deal with that, but really sticky tires that maximize the foot print are prone to let go in spectacular fashion when you reach the limit of adhesion and thats when communication and recovery are important.

SC whine on the 2011 Gt500 was fairly subdued, so it's reasonable to think that the exhaust would be loud enough to mask it.

I doubt its a big issue for the ZR1 both from a sales and capability stand point since I imagine few are driven in bad weather and fewer still are daily driven. On the other hand, those guys really wanting to run the ZR1 wil probably dig the Sport Cups since they will be doing the track day stuff.
Now if the ZR1 depreciates really badly and people start scooping them up because its a frigg'n insane car for a good price and start driving them on a regular basis then all those Sport Cup fitted ZR1s will get a nasty rep (anybody remember the NSX/Yokohoma debacle).

Like I said before, the option seems like one for the track guys who can afford a second set of wheels and tires to daily drive on. After riding in a ZR1 with the Cup tires, I wouldn't want them unless they were for track only.

one thing that would be cool for the GT500 is if they put tivct on it for 2013 to make the ghost cam idle they are putting in the boss trackkey the standard idle for the shelby.

It would be so COOL if Ford were to bring out a special edition GT500 Nurburgring mustang as they do with the Boss 302 Laguna Seca. A GT500 N-Ring sounds good. Also, I hope the new supercharger still has a noticable whine under accleration.
