Does anyone have a list of 18" rim names with narrow rims such as 18x8 or 18x9 or less with or without spacer that would clear the Brembo 6-pot 15" or the 2013/2014 GT500 brakes?
I'm looking for wheels for the winter that would clear the big brakes.
Found some Mustang that runs the Drag DR-31 or 34 rims with 18", but unsure if it will clear the 6 pistons Brembo brakes or what the offset is?? Anyone have one or know the details?

I am not sure, but my best guess is: 19x9" is probably the smallest / narrowest wheel that will clear on the front.
Try searching for wheels on Tire Rack -- you can plug in your car, and it will show all of the wheels that they sell, that will fit. I am not sure if it will recommend sizes that are different from your original size, but I think it will. If all else fails you could call them and ask, they are very helpful. I suggest Tire Rack because they have a huge selection, good on-line tools, and helpful advisors if you call them.
Wheel fitment with big brakes is mostly dependent on spoke profile and offset. Apex Racing makes a 18 x 9 inch wheel that will clear.
I know/understand you could get 18" wheels that clear the 4-pot, 14" Brembos that we have; but not sure about the 6-pot, 15" rotors? Are you talking about the 6-piston/15" rotor setup?
I would check with Apex to make sure but this is straight from there web page of the 18 x 9 inch wheels
Brake Clearance - SpokesSpokes that work for youIf the spokes of a wheel don't clear your brake calipers, then the wheel can’t be used at all. We made sure these wheels offer ample brake clearance, effectively clearing a variety of aftermarket BBK’s as well as popular factory BBK’s like the S197 14” and 15” GT500 Brembo BBK’s, as well as the S550 Performance Package Brembo BBK. The S550 GT350 would require our 19” EC-7.
^^^ yep that's pretty clear . . . unfortunately the OP probably doesn't want to pay the price for good wheels, for snow tires; and I'm guessing those race-oriented wheels are not cheap . . . I'm thinking the practical solution probably is still 19x9, which are available fairly cheap from various sources
the 19" wheel diameter means you will have to stick with fairly low profile tires, but assuming the car is not lowered, I think you can go as much as 1" over the original tire outer diameter and be OK, which will give a little more sidewall and a little more ground clearance . . . also go with the narrowest tire that will fit properly on the wheels
Thinking about 19" rims. Does anyone know if the OEM 19x8.5 rim will fit the big brakes? See attached image below and I am hoping these will fit because I have those rims.
A member from the S550 was able to fit the OEM 2010-2012 rim 19x8.5 with 25mm spacer to clear the big brakes. See attached:
I would go to The Tire Rack and look around at the wheel-tires they sell.
yep . . . I believe I suggested that earlier, not sure if OP took the suggestion . . . but I'm not sure if they have the info for the Ford OEM wheels . . . you can select your car with the options; or select a different car that has the big brakes; and then see what wheels they recommend that will fit; by looking at what comes up you can gather a lot of information
I don't think I have heard of any 8.5" wheel that will clear. You could use a spacer, but I would not recommend that, personally I will never use spacers on my car
The second photo does not show big brakes so I am not sure if that really means anything

Thanks, I have read your message, but I am still looking for other solution. Tire Rack is a good source, but they have massive big tire size and wide rims and I wouldn't want to use it in the winter. From my search, I have found others have run 7", 8" and 8.5" on a 19" on the S550 model with Brembo, but they have 7" using a spare wheel which is expensive. https://www.mustang6g.com/forums/thr...e-spare.65225/
I'm find with spacer and I have use it in the past, but I do not like spacer through.
I have finally fitted a 18x7.5 wheels over my 6 pistons Brembo brakes.
I am using 18x7.5 offset 45 with Drag DR-33 rims and tires size 215/55/18. I am using 1.25" adapter up front, but I needed to grind off the 1/2" length wheel studs. I did not have to grind off any stud threads...just the outer point of the studs that has no thread on it. Also, I had to grind part of the caliper top and bottom surface, but not too much, then I painted it. It worked out fine. The wheels look like it flushes with the fender or just a little inside the fender. The car is at stock height. Drag DR-33, 18x7.5 Offset 45 with 215/55/18.
Stud 1/2" length to grind off.
1/2" studs grinded off.
1/2" stud endpoint grind off.
I try fitting the OEM 19x8.5 wheels. It will need about 7/8" thick adapter, but a 1" thick adapter will do fine. OEM 19x8.5 with about 7/8" adapter.
I also tried the OEM spare wheel and I am guessing it would need 2.25" thick adapter, but I did not have enough spacers or adapter to try it out. I need someone to confirm that. OEM Spare wheel.
glad you got it figured out, and hope it works out well for you
I guess the point to all this was that you want to run fairly narrow tires in the snow . . . which I agree is "better" but personally I probably would have skipped all this and run the 19x9 wheels with ~235 or 245 tires and be done with it
I should have explained that in the previous post. Thanks for bringing that up.
See first attached image showing that you will see at the back of the OEM rim that has the casting “five depressions” circled in red. The OEM studs extend through the adapter and interfere with the rim.
I just cut of the end of the stud-that is not threaded.
See second attached example of the aftermarket rim that does not have the “depression” at the back of the rim.
If I drilled about a five ¼” holes at back of the aftermarket rim. I wouldn’t need a 1.25” thick adapter and could have went with 1” thick adapter.
Thanks, now I see that the adaptor is held onto the studs with lugs and has its own studs to attach the wheel. I initially though you were using a spacer with the studs passing through both the spacer and rim.
