These should have no problem fitting over the brakes. If you order them from Forgestar they are built to your specifications. http://www.forgestar.com/wheels/collection/rotary-forged-monoblock-series/f14/
I already have them for my 2015 Mustang GT and just wanted to make sure they work with the calipers. When I looked into trading my GT for a GT350 I was told my Forgestars wont work for the GT350. Was that because of a different offset or because of the brakes

It's unlikely they will fit without some sort of wheel spacer then.

Hmm. Okay. I was planning on ordering forged HREs anyhow.
What offset would you recommend so these brakes fit?

looking for the same answer, I have a set of wheels that I want to know if they fit, they are 9x20 ET40mm and 10.5x20 ET40mm. I may be able to fit spacers but not sure.
Bruce, any idea? I still don't have a GT350 that I can take measurements from.

We are running 19x10 all around with 35mm offset in front and 50mm offset in the rear. You will not have any problems with the front but may need a 5 to 10mm spacer in the rear.

thanks Bruce, but just a question for my understanding, if you run 35mm front and 50mm rear, wouldn't I need the spacers in the front to be at 35mm? I'm at 40mm at the rear which is further out than your 50mm or am I confusing something?

and is it correct that I can't run the 9x20 wheel up front, I would need to run a 10.5x20 rear wheel on the front to fit, right?

Sorry you're correct. You may need a spacer in front. You may be able to fit your 20x9 on front with a 5 to 10 mm spacer. For the best fitment I would recommend a 20x10 with a 35mm offset. What brake package is currently on your car? The 4 piston 14" or 6 piston PP 15" Brembo?

the PP 15" Brembo, it is standard on EU spec Mustangs

Does anyone happen to have a photo of the 20" factory foundry wheels installed on the GT 350R brake conversion kit? With spacers?

I am considering a brake upgrade for my car. Thanks.

Sorry for the dumb question.

I just picked up a set 6GR rims 20×10 35mm front and 20x11 50mm for my 2017 Mustang PP.

Will this brake kit install front and rear with no issues with my rim setup?

Thanks!

The front you will need a spacer so the spokes clear the caliper. You should be ok in the rear. Worst case you will need a 5mm spacer.
