Will Mach 1 HP rear wheels fit the rear of a GT350R?

[Trace]

I'm looking to change out my rear axle assemblies to accommodate the GT350R Brembo brakes.

This makes the rear track wider. But I already have 2 sets of wheels and don't want to start over.

Will the rear M1 HP wheels fit over the Brembo's? And will I have too much poke?

When looking at the wheel specs, it seems they would fit. But from at least one reply in the thread above, the answer is no, they will not clear the [front] brakes.

GT350R wheels are +24 front, +56 rear, 305/30/19, 315/30/19, 19x11, 19x11.5.

GT350 wheels are +30 front, +62 rear, 295/35/19 and 305/35/19, 19x10.5, 19x11.

Mach HP wheels are +24 front, +52 rear, 305/30/19 and 315/30/19, 19x10.5, 19x11.

Mach non-HP wheels are +40 front, +52.5 rear, 255/40/19, 275/40/19, 19x9.5, 19x10.

I have the 6 piston Brembo's front oem. I want to install the rears left over from a M-2300-AA kit. I just read through the thread and it looks like the M1 HP wheels will fit the rear. But the offsets are different...

Check.

If discussing only wheels,

From a 350R rear to an HP rear wheel, there is .5" / 12 mm difference, slimmer in wheel width. Cutting that in half, one half on each side of the wheel, is 6mm less. But the wheel change also pushes the wheel out 4mm (56mm for the R vs. 52mm for the HP).

4mm-6mm = -2mm. The wheel would tuck 2mm further in?

Ya this makes my head hurt. Is it 2mm in or 2mm out? Either way I can't see it mattering. I have some premium 5mm spacers.

i have a 2022 Mach1 with HP wheels, i dont like the look of them, so i gave them to my buddy with a 2017 GT350. They didnt fit, so he gave them back to me.

Do you know why they wouldn't fit?

I have the M-2300-Y brake kit on my 2020 GT PP2. The brake kit makes each side in the rear about 1/4" wider. I am running the same spec wheel as the HP in the rear, 19x11, 52mm offset. (Apex EC-7) Below are a couple of pics, don't think the poke is bad at all. Tires are 315/30r19's. Now, will the HP wheel itself clear the caliper? That I don't know.

they contacted the calipers.

OK I'm getting enough contradicting info to know I need to go through FP. I'll post what they reply.
Thanks all-

Those are some heavy offsets for the 350 and 350R rear wheels. I know the front fenders are a bit wider on the 350's but are the rears as well?? If not, how much do they poke?

I'd love to have 20" 325s on the rear of my PP1, stock brakes.

Are you saying you installed the Brembo parts from this kit on the rear?

 

[Trace]

You changed the rear axles to GT350 axles?

I installed the Ford Performance GT350 brake kit on my 2020 GT.:

The kit does include new axles, but I did not use them, I installed a pair of the Ford Performance axles instead.

So were there any issues with the emergency brake connection?
