I never turned the screwdriver and didn't use heat so I don't think the bumper lost any shape, but it seems like the reflector is completely ridgid and flat where as the bumper obviously has a bit of a natural curve to it.

That's really interesting. Sounds like that is the correct 3M tape I have always used. Actually if its the same Helix I know, they are located near me in Philly and I can tell you first hand they are a reputable shop with a presence on the post. Might consider reaching out to them directly (this is their website, if its the same Helix: That being said, I believe their focus is fabricating performance parts, particularly some nice higher capacity inter-coolers for BMW and Mini.

I've heard of DEPO (as i recall they used to make replica "blacklines" for e90s and other lighting products), but I think most people would consider the IND painted reflectors to be the benchmark - they are probably a bit pricier but worth it in my opinion. Also, I think you are right that there is a slight natural curve to the reflectors having just removed my painted ones and reinstalled the OEMs - both had that slight curve.

Maybe you can use some heat to bend these to a better shape? Obviously be careful not to mess up the paint though.
