^^^ i didn't install the kit. it was done by Studie (a tuning shop) located in Japan, it's their shop/demo car.
as far as i kno, there wont b any major modifications needed since the kit is oem. they hav access 2 the parts.
fyi the m6 n m-sport rear bumper n sides r the exact same, all u need is an m6 diff.
as 4 fenders, it looks like the f12/f13 fenders r a direct fit. same goes 4 the front bumper.
that bein said, u basically need:
- m6 front bumper
- m6 fenders
- m6 sideview mirrors
- m-sport side skirts
- m-sport rear bumper + m6 diffuser
