I bought some replica trd rear splitters for the coupe/vert, and they aren't as flush as i would have liked, i can stick my thumb inbetween the gap. Anyone have any ideas what I could do to fix this, ive already been told glue/tape wont hold. I tried double sided 3m tape and it doesn't hold.

I had the same problem but instead of trying to make it stay to the body..I lined the splitter with super thick truck bed liner. It just reduces the gap. i've been happy with the results.

can you post up some pics?

Back when there was snow on the ground haha





I'll try and get some better ones for you tomorrow..I got the liner from advanced auto. it's pretty standard. it's also good for interior rattle resistance haha
