    I'm swaying back and forth on picking up an E46 M3 and buying my first Muscle car(Mid-life crisis time). The 2015 mustang has my interest, but some of the ordering peculiarities are getting in the way for me a bit.

    looks like I can't get a non-premium, non performance pack GT and upgrade the wheels beyond 18x8 per the street rules as that's the only way you can buy them, at least by the website. $33k

    The performance pack puts you into a 3.73 final drive, which I don't think would be the best. There is a non premium here for $37k (found another without Recaros for $35k)

    Premium version lets you choose your wheels, and get the stock 3.31 diff(non-Torsen of some kind ?), or 3.55 if you order it, or find one, but $$$. 40k plus.

    I guess I'm wondering if I could get enough power to the ground with the non-performance pack, non-premium GT with the 18x8's and a 265 square setup, and or what peoples thoughts are on the different ratio choices vs Wheel options. I know drag guys will put 275's on an 8 inch wheel, but I'm guessing that might be pushing sidewall flex, 265's might not be a good idea even. I don't have the level of experience with these levels of HP to know.

    265's on 8" wheels is going to less than optimal.

    Yeah, I felt some of that running 245's on a 7" on the 08' WRX.

    I'm guessing it will be worse with a 700lb heavier car with a ton more TQ, and it gets HOT here in Tejas...

    Chris Cox, current Super Street National Champion in a GT3 recently purchased a 2015 Mustang GT and is preparing it for FS. His car is a standard (i.e. not premium) GT with performance pack and recaros. If you don't really want recaros the cloth seats are very comfortable and from comparing Chris's car weight with mine the power seats are only about 10 lbs heavier per seat.

    I don't have the details but my understanding from credible sources is that the performance pack also has significant bushing differences including changing to a stronger type (not just durometer). Plus chassis stiffening and spring/bar changes.

    The non Torsen diff is the Ford Traction-lok clutch type diff that with solid axle cars tends to need frequent clutch plate freshening for maximum "limiting".

    The car accelerates so fast that I'm not convinced that even with 3:31's "running out of gear" wouldn't be frequent. The car is very strong in 3rd with the 3.73's.

    Additional Street class legal wheels currently mean ordering a set of Forgestar CF5's with the proper offsets. However, I've been told that Tire Rack expects at least one supplier of Street class legal 9/9.5 wheel sets soon. Sam Strano is a good source for ordering the Forgestars which are custom made to the offset and color you want.

    I put a deposit down on a comp orange, non-pp, non premium today. It won't stay in F-street long. I've been wanting to build something nasty for a while, so it's heading to ESP soon, but I will test it with 265's and see how far behind Brian Burdette I am.

    Should be a decent starting canvas for something that might be competitive next year. I have my bankruptcy lawyer already lined up...

    Sounds like a good decision. FYI these videos describe the suspension "bushings" I was mentioning. I assume you can either update/backdate in ESP and/or replace with aftermarket. I haven't looked at mine yet to see what they really look like with the pp.

    FYI: I was 1.6 seconds per day behind Brian in his 2012 at Nats in 2014 with an over the hill driver, 2012 normal GT automatic with 18x8.5 rims and 265 ZII's. Hopefully you will be a lot closer than I was. Has Brian changed to a 2015?

    Edit to add: I was 1 second behind a couple of other "not so young anymore" drivers (Kevin Younger and John Ames) on the East course and basically the same times as them on the West course. They had a properly equipped (Brembo package) 2012 on Hankooks.

    I am thinking for FS, a Base GT + PP is the way to go. Yes the gearing is wrong, but the other stuff in the package make up for it.

    Now for ESP (or even STU), a Base GT might be a better starting point as you can add wider tires, better suspension, and chassis reinforcement to equal or better the PP parts.

    Now my car will eventually see some track use, so the big brakes by themselves make the PP worth the money. And you can change the final drive once you get out of Street.

    The base GT is a good deal lighter to start with, and I'd think a good portion of the parts in the PP would get swapped out in ESP anyway.

    It's going to take a bit, though. Looks like only one option for coilovers right now, and they're just S/A Koni's with threaded sheaths over them... for $3k. They have a more full-on version with D/A's for $4,500. (Cortex?)

    I think at some point I'll bump to a Wilwood package for brakes.

    Brian was in a focus ST at the last race.

    Regarding weight: Base GT's with Performance Pack weights from several autocrossers

    #1: GT, PP, Recaros, FULL tank: 3733 (trunk stuff and mats out)
    #2: GT, PP, Recaros, "full" tank: 3708 (I don't recall what was removed)
    #3: (my car) GT, PP, power cloth seats, back-up assist, full tank minus probably 1/2 - 1 gal: 3752 (inflator and trunk mat out, floor mats in)

    Regarding adding selected performance pack parts "back in" as needed for ESP or track use I've been looking at the fordparts.com site and it appears that at least some of those parts are "bolt in" relatively small parts rather than major big stuff so it might be practical/cost effective if you want to go that route.

    I'm hoping I can get a weight and baseline dyno sometime soon after picking mine up. I'll try to set it up as autocrossed. That big azz subwoofer isn't standard, I hope.

    I've been initially pleasantly surprised at what it looks like part prices will be. It appears that they will generally be substantially cheaper than M3 parts.

    The subwoofer is an extra cost option with the premium GT.

    I picked up a base 15' GT on Sat. Autocrossed it in the rain on sunday on the 235's, and I thought it was pretty composed (with only half the traction control off, not intentional.)

    Now for the learning curve...

    I ran 275/35/19 Hankook RS3 V2's on 8.5" wheel. They were not pinched at all, in fact, they are flush with wheel outside. Other tires may have a different effective width. I agree the track package is worth the upgrade. More than just gears. And any of you V8 guys will continue to kill my '13 V6 since both cars should be in the same class according to the rule makers. Welcome to Mustang. I love mine, unfortunately gotta find something else for autocross.

    Most people probably wouldn't care about the forum. I am sure there are one or two that might be very good though.
