does anyone happen to know if a justa cooper jcw aero kit will fit directly to a cooper s if you swap out the rear diffuser?

 

I'm banking on it. I contacted ECS and they said it will. Thats what I had to do to get a JCW Aero Kit when they were blowing out the blackline kits. I'm just going to install a GP rear diffuser and attempt to sell the Cooper rear diffuser.

 

Perfect, I think I'm going to give it a try as well!
