GT500 Wheels on Mach 1

[OhioHPMach1]

Will GT500 wheels fit our cars? I have the handling pack and the Steeda Ultimate Handling springs. A set popped up on market place I was thinking about jumping on for a track set of wheels.

Wheels:
Front: 20x11 offset +32mm
Rear: 20x11 offset +50mm

Tires:
Front: 305/30ZR20
Rear: 315/30ZR20

Yes, should not be a problem.

"The GT500 has a unique front suspension geometry with different knuckles, ball joints, and control arm setups than the standard GT. The control arms are upgraded to provide more track width, camber, and roll center adjustment."

As to your question, I honestly don't know, but I wouldn't assume. The 20" tires are more expensive, plus it would be my guess, maybe someone can chime in, the standard GT500 20" wheels are likely heavier than the wheels on your Mach 1.

If you're wanting them just to track the car, I would look for a set of Apex 19 x 11 or 19 x 10. The 11's fit with the help of extended front studs and the square setup means you can rotate them front to back and help with tire wear.

I wouldn't use 20's as a track wheel. Tire availability, lack of sidewall, added weight, not rotate-able, I am sure there are about a dozen other reasons to not want them.

Unless they are the CF wheels. Then yes, have at it.

Thanks all. Going to pass on them. Great points.

I understand they need the 20s to clear the bigger rotors and calipers which isn't an issue in the Mach 1. Unless you are gifted a set of the carbon fiber GT500, aftermarket is better. Even then the carbon fiber tires slide on the wheels when fitted with stickier tires.

I run Apex 19x11 all around and no need for extended studs; however, I don't use a square setup since it would require spacers which damage the wheel bearings.

If you aren't running square, a spacer is just built onto your wheel instead of being a separate piece. The physics are no different.

Spacers themselves do not damage wheel bearings. Improper fitting spacers would over time. I personally have never know anyone to sustain a front wheel bearing failure due to a spacer for track use. The cost of track tires far outweighs the cost of possible wheel bearing damage.

Steeda has seen this issue in their #20 HPD car.. not just once. It's mentioned in the first 2 minutes of the video. I would agree that changing the bearing is less costly. I think you can take your chances with the improved knuckle and bearing in the M1 over the GT. Someone here mentioned that longer studs or spacers are equivalent physics. I just argue that the more distance from the bearing you have... you are introducing a higher catentelever force. To me it would make sense you are taking a risk. Spacers come in various design also so it's a deep rabbit hole.

OP has a 22 Mach 1, not a 15 GT.
