The fact that you got it in without cutting the inner wings is a really game changer. especially as mine is a clubman.
I was considering doing this conversion now im even more tempted.
The whole aim of my MSC work which started this project was to design a kit that required 0 body modifications.
The frame you see above is not exactly body modification free as you do have to pull the bottom of the inner wings out but there is no cutting or welding.
