Think that he's showing how much space he has there to see if a spacer would be okay, but that it's rubbing on the inner side.
Either way, looks tight there as well.
Finally had time to go to test wheels. I taught 2 of them had different offset because MG TF it Mid engine and has bigger tyre size in the back but the 4 wheels are 15x6 ET28.
It looks really cool in the front but needs spacer in the back. Tomorrow I will make pics to show you.
