Has anyone got a copy of genuine BMW F32/33 side sill extension fitting instructions? I know that look straight forward but want to be sure.

Went to local BMW dealer and asked for a copy of fitting instructions in the end. Straight forward fit, see photos. Car is just lowered of jack so suspension hasn't settled yet.

Did you do the rivets and screw both sides, would appreciate a quick run through.

F32/33 only has 15 expanding rivets and double side tape no screws. BMW fitting instructions say add liquid adhesive which runs parallel to the tape but I didn't bother as the expanding rivets give a strong hold.

Gave sills a good clean and then again with 3M VHB cleaner ready for the tape.
Aligned sill starting at the front, grove in sill extension allows for a butt against front wing.
Make sure groove the full length of the extension fits over the raised part of sill, most inner part of sill lip.
Start pulling off tape few inches at a time and pressing to secure tape bond to the sill.
Once full length completed jacked car from the front jacking point raising the car quite a bit to get in with battery drill to drill the 15x 6mm holes and started to fit the expanding rivets. Got most holes drilled just raising the front but had to lower and raise again at the rear to get the last 3, job done.
Second sill extension took a lot less time to fit approx 15 mins, about 40 mins both sides.

After buying a replica rear defuser and finding the quality poor and I wouldn't fit to car got refund and bought genuine BMW and very pleased with fit so when purchasing sill extensions went straight for genuine BMW with a discount, not cheap.

I can totally understand why you did that,makes sense.
I got mine cut down & they are currently getting painted along with the front splitter,
Time will tell when I fit them at the weekend
