Looking at buying a new 2015 GT. Wondering if this upgrade is worth it? I'm going to do a dealer order and the only options I would look at are this and the lighting kit. Just looking for a no frills car that goes fast and handles well. Should I get this option or upgrade the tires, rims, brakes, suspension as I own the vehicle?

 

There are pros and cons of the Performance Package (PP). It all depend s on what you want to do and are willing to spend on upgrades.
If you are only going to street your car with spirited driving here and there, the PP is not a bad deal.
But if you are going to track your car, you will be changing nearly all of the PP parts anyway. You should consider your costs for aftermarket parts vs the cost of the PP and what it offers and work from there.

The pros of the PP is that the car comes right out of the factory with a Torsen differential along with the 3.73:1 rear gear, upgraded radiator, and Brembo brakes.
The PP also comes with upgraded K-brace and engine bay strut tower.
The PP is also relatively cheap; just under $2500 added to the base GT price.

The cons are that the PP's upgraded shocks, springs, anti-rollbar, staggered rims and tires, and "uniquely tuned stability, EPAS, and ABS" aren't all that great as compared to what the aftermarket offers (or will very soon offer).
The shocks, springs, and anti-rollbars are really only meant for the street and are not suitable for road course competition (if that s what you intend to do).
Same for the PP tires and rims. Track competitors change those anyway.
The PP tuning for the EPAS, ABS, and stability control are also unsuitable for competitive track use.
The PP ABS seems to activate needlessly at certain times due to "being confused" at times on less than ideal road course surfaces (I think this thread's vid shows the PP ABS activating in wrong conditions https://mustangforums.com/forum/the-...py-shocks.html ).
The PP stability control is overwhelmed by the PP shocks, springs and anti-rollbars inability to perform properly in competitive track conditions (see the vid in the link).


In the end, it is all up to you in what you want to do. If you are not looking for a track competitive car but want NVH comfort with no sacrifice in daily driving smoothness and ride quality with just a little more above just the plain 'ole GT, then the PP is not bad choice.
But if road courses competition-like handling is what you want, you would probably are better off starting with just a plain GT and upgrading everything yourself. You will spend much more than just $2500, but at least you get to choose components that would best fit what you want and/or intend to do.

 

I often wonder about this myself, and as a basic starting point, how much does everyone think it would cost just to up grade, the radiator, brakes, Torsen with new gears, and to redo the dash to replace the 3rd air vent with two gauges.
Seems like it would be well on the high side of $1500 very close to $2000.

 

If you figure in the labor its almost always cheaper to just buy the PP. Gears by themselve are a $700-$1000 purchase (all parts plus install). I know some one will chime in and swear they know a place that'll install for $200. I don't like those kinda shops working on my car. Learned my lesson. I also agree with Jim. If your building an actual track car just bite the bullet and buy the coil over, light weight wheels and the best tires and brakes you can find.

 

Not going to road race it. Probably do a quarter mile at an open night every so often but looking for a little more performance out of the gate. I'll end up modding the motor but it'll just be a fast daily driver. Sounds like for that scenario it's worth it. How much of a difference will the gear ratio from stock to PP be?

 

in my 14 the stock ratio is 3.31, but I could order any I wanted, 3.55 or 3.73. The difference is in the torsion differential on that end. To upgrade the radiator it is at least $500 plus install, gears are variable depending on where you get them and how high of quality.. right now go with ford racing parts since they already have a selection, I would guess $200 with everything, add the torsion and that is $7-800. tires and rims will cost what you are willing to pay... anywhere between $1500 and up, and none of these include the install, so the PP is probably worth it for what you are doing.
For drag racing everyone always wants the 3.73 gears, but if you don't have tires to support that short of ratio you will just spin off the line, and with the IRS you will also wheel hop like crazy. I have the 3.31 and yes I can spin them, but it is a lot easier for me to launch my car than most other guys out there, and I don't have to shift 10 feet before the finish line like a few friends do. I also don't wheel hop with the stock suspension, but most people with the 3.73's do, so you will want to upgrade the rear end if you drag it more than a few times...
hope that helps

 

Thanks for all the input. I'll probably end up going with the PP. Where I'm at now there are only 1/8 mile tracks so I probably won't be doing much of that. Just looking to embarrass all the "C" cars around town

 

In this case, the PP is perfect for you. If you take it to the dragstrip, the only thing you might need to consider an upgrade are the rear shocks and springs and tires to improve grip.
Of course, engine bolt-on mods and a tune to increase power; always for the better on the street or on the dragstrip.

You don't have to go all out and get drag radials or dragstrip-stiff shocks and ultra hard springs; just something in between the stock PP equipment and dragstrip equipment would be more than enough for the spirited driving and occasional street bruising you will be doing.

 

IMHO, if I was going to order a new '15 I'd go:
GT with PP & Premium
Those 2 pkgs can't be beat for value to the new owner, just try comparing everything you get to adding aftermarket parts..

 

Does anyone know why they do not offer the PP in the automatic? Especially, because they offer the PP in the eco boast automatic.
