Custom offset (05-14 GT) forgestar wheels fitment on 2015 GT

[Turbos550]

Hoping someone can help me figure this out. I am looking to purchase a set of wheels and tires for my 2015 Mustang GT. The wheels I want to get are Forgestar CF5V. Fronts: 19 X 9.5, Deep Concave, Offset +33, Rears: 19 X 11, Deep Concave, Offset +53. I am told they fit all 2005-2014 mustang models and 2007-2012 GT500’s. Not sure about 13’ & 14’ GT500’s brakes.


Tires: Fronts: Nitto NT05 275/35 ZR19

Rears: Nitto NT05 305/35 R 19 Drag Radials


Everything is brand new in box so test fitment isn’t possible as the tires have not been mounted. Reason why I am considering this set is the price. They are coming from an individual who purchased new but never used them.


Here are the specs of the factory mustangs for the two generations:


Stock 2014:


Lug pattern - 5x114.3

Stud Sizing - 1/2”-20

Center Bore - 70.6mm

Offset - 35-50mm


Stock 2015:


Lug pattern - 5x114.3

Stud Sizing - M14x1.5

Center Bore - 70.5mm

Offset - 35-52.5mm


My current wheels: Factory foundry wheels - 20x9 square with 42.5mm offset I believe.


I know nothing about this stuff and wondering if this specific set of forgestars will work. If not, would I need caster camber plates or a spacer of some sort to bring it in speck and flush? If it helps, my car has Eibach Sportline springs and PP brakes (6 piston brembo calipers, 15” rotors.


Thank you very much!

Shouldn't be a problem.

The S550 seems to want a little less offset than the s197. But this does not push the limits.

Personally I would want a bit more front wheel & tire, but drag radials suggests handling is not your top priority.

Thank you for the reply. Glad to hear you’re thinking everything will fit. I’m making the decision to drive the three hours to pick them up tomorrow. I received about the same response from Howey Industries (where they were purchased). Here was the owners response:
“I just talked to Howey Industries... he said he is fairly certain they will fit. He said they will be slightly aggressive, meaning they will be very close to or flush with the fender. He said for the S550:

Front- they spec + 35 for the front (mine are + 33, and I see American Muscle specs + 29)

Rear- the spec + 56 to + 58 (mine are + 53, and I see American Muscle specs + 55). I just googled and found an S550 wheel sizing guide from Apex Racing- they recommend + 52.”

Handling would be a plus for sure. The car is my weekend car that I plan to road course a few times a year. The 19x9.5 is slightly better than what I currently have (19x9). I’m told slicks are what you want for the track (maybe not a radial) but should definitely perform better than the 255 nt555 G2’s. The car is in the process of being twin turbocharged and will get around 850+ wheel. Won’t use it all on the track but I will need the radials for the road when it’s turned up.

Thanks again!
