You can probably get all of the parts, but you won't be able to get the tuning. When one of the Ford engineers was here he made it quite clear that it wouldn't be easy to duplicate the track pack on your own...

 

Track Pack-equipped ‘Stang adds a unique set of dampers, a front strut-tower brace, carbon fiber clutch plates, shorter 3.73 axle ratio, a limited-slip differential, dual-piston front calipers with performance brake pads, recalibrated stability control (AdvanceTrack tuning), a set of cast-aluminum 19-inch wheels with 255/40ZR19 Pirelli P Zero summer performance tires, plus several pieces from the current Shelby GT500, including its front and rear antiroll bars, rear lower trailing links and front upper strut mounts.

 

This must be what it feels like to have your kid come home with a report card that is straight A's.

 

I think the Pirelli P Zero summer tires are a lot more expensive than the P Zero Nero all season tires.

 

Items 1-6 are from the 08/09 Bullitt for the '10. My question is about the rear end. Is it from the GT500KR?

As reported by RCSignals and confirmed by Ford Engineer s197_guy, the 08/09 Bullitt has the KR rear end. I'm wondering if it carried forward into the 10 and/or 11. Just out of curiosity.

The following is the complete list of all upgrades for the Bullitt 3.73 axle:

1. Higher strength differential case material
2. 9x13 differential gear tooth combination (GT is 10 x 14)
3. Differential gears receive premium shot peening
4. Anerobic adhesive added between the differential case and ring gear
5. Higher capacity head bearing (with shim)

All other components in the Bullitt axle are common with the base GT 8.8" axle

Also, the axle code is V-257. The code is found on two stickers on the axle. One is on the right axle tube, near the vent cap. The other is on the differential cover.

RCSignals did add some additional precision to the response about the axles. They are 31-spline units tucked into the thicker tubes from the GT500. Also, the rear differential gears in the 3.73 units are stronger for duty in the GT500KR.


Ford Bulletin: effective date 11/12/2008: 20545 2007-2009 Mustang GT 500 and Bullitt – carbon fiber limited slip-noise-normal characteristics.
2007-2009 Mustang Bullitt and Mustang Shelby GT 500. The Mustang Bullitt and GT 500 limited slid differentials are equipped with heavy duty/racing type carbon fiber clutches. This type of limited slip differential may exhibit a chatter or moan groan noise when making sharp low speed turns. These noises are a normal characteristic of the heavy duty/racing type limited slip differential.

 

yes they are . . . and you'll be lucky to get more than 10,000 miles out of them . . . makes me wonder whether I really want the new V6 Performance Pack

 

10k? Thats it?

 

depends on driving style. I think the treadwear rating is 220. If you drive halfway normal you can get 15k out of them.

 

Only if you drive like your hair's on fire all the time!

On my '99 Lightning I had Nitto Drag radials and was warned that I would probably not get more than 7-8K out of them but I got almost 15K out of them and that included racing about once a month.

All depends on how you drive.

 

which pirelli pzero tires are they exactly
tirerack lists 4 in 255/40/19

pzero (no service description)
pzero rosso 96w
pzero rosso 100y
pzero system 100y

 

By my new found internet knowledge thanks to wikipedia , I calculate the summer only tires will last about 25k miles if you drive normally.

According to wiki the treadware rating can be used as a ratio to compare the tread's life to that of another tire. Meaning a tire with a 200 rating will last twice as long as one with a 100 rating (estimating of course).

I compared them to the stock Pirelli All-Seasons on the GT, which have a treadlife warranty of 45k miles and a tread rating of 400.

220/400= 0.55
0.55*45000=24750 ~ 25k miles

Of course driving and road conditions can alter this value dramatically

Treadware doesn't mean ****. You can also only use it to compare to tires of the same make as there is no standard. I've gone 40,000 miles on 180 treadwear Bridgestone summer only and 15,000 miles on 300 treadwear BFG KDW.

 

Good thing they are both Pirellis!

I want my internet calcs to be worth something

 

that's about what the Camaro guys say they have been getting . . . maybe a little more like 12-14K, maybe a little less like 8K . . . I can't say from personal experience because I have none . . . obviously it does depend on how you drive; but the are a soft compound which is partly why they work so well

 

I'll just throw a supercharger on the CS and call it a day

one mo time!!! that body style DID NOT GROW ON ME.

front A+
rear D-

I just can't cope with having an ugly azz, especially with all the cars in my rearview.

 

Dangit Bert you're throwing a wrench in my plans! I don't want tires that only last 8k...

 

you probably should find some more reliable information to make the decision, my "internet wisdom" is notoriously unreliable!

I was pretty shocked when I read it on Camaro5 . . . but you know how those Camaro guys drive ;-) . . . when the first set wears out you can always replace them with something harder

 

Lol I'll take it with a grain of salt

 

You will get more than 10k miles out of them as long as you aren't doing burnouts like you are seeing on these videos. My 997 has the PZero summer tires and I have 20k miles on the front and the rears went out at 13k miles. Keep in mind a 911 has 63% of its weight on the rear of these cars and they chew up rear tires at an alarming rate. I think you could probably squeeze 15-20k miles out of a set as long as you aren't tearing up pavement every chance you get.

Also, manafacturers have different ways they rate tire wear. You can't compare a Pirelli 220 treadware to a Michelin, it has to be among the same manafacturer.
