Hi All,

I have a question regarding 15" wheels on the roadster. I like the look but understand that there are certain limitations that one must accept in choosing to go with the 15" wheels. Specifically, I understand that you can't order the Wilwood upgrade from factory five if you decide to go with the 15"
wheels. I have also heard that the new IRS requires some modifications to work with 15" wheels.(Please correct me where I may be incorrect in these assumptions)
When I do a build I will probably be well served to keep things as straightforward as possible. Thus while I understand that there are probably workarounds which would allow me to have IRS and Wilwoods with 15" wheels it would probably be best for me to go with 17" wheels instead if running 15s necessitates too much added complexity.

Thanks,
Zach
