i bought the rs1 sides and rear and i just want to know where you guys put the screws and where you put the 3m tape. Obviously I want the lips to stay on but I don't want to over-engineer it.

 

On the sides I've seen two screws in each end (the wheel well area) and I've heard one or two on the underside into the OEM skirt can help. As for the 3M tape, I would assume just space out a couple random pieces to keep it from moving around.

I saw a kit on an RS1.0 tC at the Scion VIP Campout that had a LOT of rubbing from his lip kit moving around. The bumpers had some major wear from the kit sliding all over. Apparently did not use any (or enough?) 3M tape.

 

alternate screws under the sides and double sided tape every 5-6 inches

the rear I would use as much as possible to mount it up. don't want that rear flipping off doing 80 on the highway!!!

 

use 3m double tape and make sure you do not crack the material
