SpoolinX2 Posted April 16, 2012 Report Share Posted April 16, 2012 So I might have a chance to pick up a set of stock 19x9.5" '11 GT500 wheels cheap (the split 5-spoke design). I know these should fit...I'm just unsure of backspacing on them. Any one know if these will for sure fit, or not? Also, if anyone could photoshop a set of them onto a silver SHO, I'd be much appreciative. Link to comment Share on other sites More sharing options...
EcoBrick Bob Posted April 17, 2012 Report Share Posted April 17, 2012 Do you have any idea what the offset is on those wheels? If you get a number you can calculate how they would fit with an offset calculator. Link to comment Share on other sites More sharing options...
FLIP-4-SHO Posted April 17, 2012 Report Share Posted April 17, 2012 The mustang and SHO have different hub sizes I believe. Mustang is larger. So you will lose your hub concentric location design and be relying on bolt pattern. Link to comment Share on other sites More sharing options...

So you will lose your hub concentric location design and be relying on bolt pattern. Hub Rings can solve the hub-centric situation. The bolt pattern for the Mustang and the SHO, MKS, MKT, Flex are all the same. The 18" wheels I purchased for my Flex came from the Mustang selections on TireRack's website. They were (8") 40 offset vs (8") stock 38. These ASA wheels are quite close to touching the calipers, especially when I replaced the rotors and installed new pads. It is possible for a wheel to fit with worn pads, and later rub when new pads are installed. A 3 mm spacer can be successfully used with the stock wheel studs. Anything thicker, requires longer studs and works best with a spacer with a built in hub flange. The biggest issue you could have with 9 1/2" wheels is whether they stick out too far, or if the offset is not great enough, that they might rub on the calipers. Generally, the wider the wheel, the more limitation as to offset variation. Link to comment Share on other sites More sharing options...
Crash712us Posted April 17, 2012 Report Share Posted April 17, 2012 I am very interested in this, as I am very fond of the 2013 gt500 wheels and have ponder the same thing. Link to comment Share on other sites More sharing options...
