What size tires and wheels?
I I’m thinking about going to a square set up on my 2022 MACH 1 with the handling package.
Thank you.
I was using a very wide, tall package. 20x11.5 wheels with 335/25/20 A7s. With a camber setting that cleared the outer fender (around 2.5) they came very close to the shock mount and MR wiring.

On your M1 just stay away from 325 or larger :) 305-315/30/19 is a great size for a square setup.
 
Stan is correct, I ran 315/30/19s all the way around when I had my Mach 1 ( OP Mustang 25mm spacers and I got some studs from Capaldi Racing )
So what did you find the pluses and minus of running the 315’s all the way around?
What kind of modifications did you have to do?
What wheels did you buy because I’m assuming I would have to buy a new set of front wheels with different offset than stock HP wheels?
Thank you.
 
Running with 19x11 Apex wheels, 25mm spacers and elongated studs , I really found no negatives with close to -3 degrees negative camber up front and -2.2 in the rear. I ran a set of 305/19s also and they were fine too. One thing I would suggest though, use the specification info on TireRack for any of the tires you might decide on. Sometimes you find certain tires have quite a bit more section width and tread width and then folks can have some fitment issues. Plus you do need to have reasonable negative camber up front. I did get set of Vorshlag front brake ducting plates as I did not want to put hoses up front or have that cramping the wheel well. Your best bet is to call Apex Wheels and chat with them and you can also drop to the bottom of their website and hit the " Fitment " button. Cars can always be a bit different and I found on my Boss 302S when I was running 18x11s that my tires wore on the rear bar. I had to put a small spacer in the rear to alleviate the problem. When in doubt always check with plenty of folks and some folks stay with 305s as they are a guarantee fit.
 
PS - full set of Apex wheels , squared, all the way around. They are on Sale now and I would get a set of " Forged " ones as they are super reasonable now --- who knows what they may be if tariffs hit next year. They are made in Taiwan , so hopefully no effect , but one never knows.
