Roush wheels are 10" wide with 45mm offset. But that's a moot point, and the steering stops are required on their 20" wheels..required so the wheels don't smack the inner wheel wells. A 9.5" wheel would require no where near 45mm et. A 9" wheel only requires a 30mm et.
WRONG !!! And I strongly suggest you look at the Roush website.. In fact they don't even list 20x10 wheels anywhere on the site under 2005-15 Mustang parts..
All wheels for 2005-2015 Mustang are listed as 20x9.5 and require the steering stops on their 20" wheels... In addition, I recently purchased a set of Steeda Spyder 20x9.5 wheels which are also 45mm offset..
As for 9" wheels only requiring 30mm offset, wrong again.. As not all have just 30mm offsets.. FYI I was also considering the Mickey Thompson SC-5 20x9 wheel which have 32mm offset and also Niche Verona Anthracite 20X9 wheel with 35mm offset..
Posted below are links from Roush, CJ Pony Parts and LMR that list the offset for the Roush 20x9.5 wheels at 45mm.. And btw: the Roush wheels were also one my choices as well in which the Roush tech I spoke with also confirmed the offset is 45mm along with the 20x9.5 wheel size..
In the end, I decided against the Roush wheel package after the tech rep I spoke with confirmed the steering rack stop kit is definitely required..
Prior to purchasing the Steeda Spyders, I did have doubts about clearance with the 45mm offset, however after the tech rep I spoke with assured me about the Spyders being engineered specifically for the S197 Mustang and are designed to fit properly in addition to also being included on their Steeda Q series models, I finally made the decision to place my order and received them 7 days later..
With that being said ! Here's the links including specs..
