I searched the Mach1 forum and not sure if this has come up. Concerning the Mach1 HP - has 10.5" wheels in the front & 11" at the rear. I was going to go with the 11" Apex EC-7 wheels all round and add a 25mm spacer to make up the difference in offset for the front. The sales tech told me that I would have to run -2.75 deg camber at the front. The HP allows for adjustment which I got to -2.5. The track spec in the manual is -2.25 deg. Has anyone put on 11" wheels on the front and 305/30/19 tires without any issues? And what front camber do you have set?

There's gazillion discussions on this and yes, tons of people run 11" wheels with 305 tires on S550 platform. -2.5 camber would be sufficient. Here's Apex specific thread: https://www.mustang6g.com/forums/threads/official-apex-wheels-showroom-gallery-thread.76793/

PS in addition to 25mm spacers, you will need extended studs.
Thanks for the link. I went through all the pages of it and found that 'bnightstar' was running the same but mentions the camber at -3deg is a must.

Here's a few pics of my car with steeda trident wheels with 25mm spacers up front and virtually same offset as apex wheels (53 vs 52). My camber is somewhere between 2.5 and 2.7. don't remember exactly. https://www.mustang6g.com/forums/threads/need-help-choosing-tires.183386/page-2#post-3696739

Steeda says that 23mm spacers work with their wheels, but I never tried this. You might want to double check with apex if that would work.

On my 2020 GT PP2, I am running 315/30r19 on all corners with Apex EC-7 19x11, 52mm offset wheels. Using a 25mm spacer on the front. Front camber is as it came from the factory, I have never had it aligned. (I think factory is 1 degree or so.) Suspension is completely stock, I have no rubbing issues what so ever. PP2’s have the same wheel/tire spec as the Mach HP package, so I would think you should be good. Below is a post with some pics of my car.

Appreciate the pictures. Love the car colour. Yeah I sent Apex an email asking the question. Steeda wheels are also an option.

More negative camber just helps manage the poke (it's also good for handling and tire wear on track of course). Mach 1 HP's have those plastic fender extensions, so it's even less of an issue. Otherwise, there is tons of space. If you don't want to swap your factory camber plates, you could use quality camber bolts to dial in camber some more.

You can run 11” wheels, no spacers. But you will need different offsets. If you go on the Apex site they list the options that will work. I have 19x11 apex wheels. Different offset on the front. Running 3.1 negative camber with Vorshlag camber plates.

The whole idea is to just have one set (plus spare) of wheels all the same size that will fit back or front. That is why I want the 25mm front spacers so I can use the 52 offset wheel on the front as well.

Ian,

Im going with the same set-up, using slip on spacers with extended front studs.

Yep, the smartest idea for sure. In hindsight in the early days I would have done that too, but right or wrong, I thought wanted to throw my HP wheels back on for the street, and not have the studs or spacers to deal with. Turns out it very rarely sees the street!!

Now if it’s a dry track, I just swap left and rights for the track, I can balance the wear out a little. Especially tracks that are hard on one side of the car. Running the most camber I can has helped even out that wear across the tire.

Thanks. What camber do you have?

Fwiw (GT not mach juan), you kinda want a bit more than 3 degrees of camber to get the most out of the front tires if you’re tracking it. You can get close with some of the camber plates, and if you open up that strut tower hole (vorshlag sells a jig to do that surgery) you can get quite a lot more.

i’ll also say that some of the good tires also come in 315/30R19 (or 315/30R18) and if you buy slightly wider spacers and studs (OPMustang sells wider and longer parts) you can fit 315s square on the car with those same ET52 wheels.

Can confirm I opened up the strut mounts with that tool. Painted the cuts and finished with some o ring seals. Looks pretty factory imho.

So when you say wider spacers (wider than the 25mm spacer) it's because the extra width of the tire (305 to 315) has an issue on the inside clearance?
