Can I put 20" wheels on Performance Package?

[Rash]

I'm gonna order an 18 GT PP, but don't like any of the '18 wheel options. I LOVE the 20" Foundry wheels offered on the current car, so I was hoping to buy them somewhere and put them on the '18. But I notice that Ford doesn't allow the 20" wheels on the current PP car. Does that mean I am stuck with 19" or less on PP?

Huh? 20" wheels should fit. Check the offset, but you should be good.

You'll be fine. Just because they don't offer 20'' wheels on the performance pack doesn't mean they won't work.

I just assumed that maybe they don't offer the 20" with PP because they won't perform as well with the stiffer suspension or some similar reason.

is everybody sure that the 20" wheel doesnt hit the Brembo Calipers on it's mounting surface?

I've seen people swap Foundry wheels to performance pack cars before - so unless they change the brakes it should be fine.

Ughhh ya. That's what I run.

I have the 20" wheels from the factory. When you get a 20" wheel car from the factory they also add the cowl brace, and same bottom cover as the PP cars with the oil filter flap, (I think one other thing as well). For some reason only the 20" wheel non-PP cars get these from the factory, or so I believe? I plan on adding Brembos, and they will work from everything I've read. As far as suspension I run GT350R springs with Koni shocks which are much stiffer than the PP suspension, and it works excellent with the 20" wheels.

The clearance is too tight for the factory 20" wheels and brembos from the PP. As things heat and expand, and cornering forces are exerted, you risk contact between the caliper and wheel. Spacers or don't do it.

I have 20" wheels with Brembos. You may want to use the base rear sway bar if you go square. I prefer square so you can rotate the tires. I have 285/30 x 20 and am very happy. This picture is pre Brembo because I could not get Brembos with an auto, so I bought a CS, and got the strut bar and such and then bought the drilled and slotted rotors and added the Brembo calipers. Very simple swap.

I have 4 piston and 6 piston calipers in my garage and they are the same size. The difference is how they mount. The Brembo branded ones (made by Continental) have a 1/2" longer mounting ear to accommodate the 1" larger rotor.

20" wheels

Go for 20"... mine is a Roush with the PP and it fix perfectly... my car came with the Roush quicksilver 20" but I exchange it for another set of 20" and I never had any clearance issues...

I think he's talking specifically about the factory 20x9" Foundry wheels. I'm not sure what the offset on them is but I would imagine they'd fit on a PP car as those come with 9" wide wheels up front as well.

Yes - referring to specifically the factory 20x9 Foundrys.

If they would work, why doesn't Ford allow you to choose them as an option on a Performance Package car?
