Does it bolt on to your factory bumper mounts or did you have to drill new holes? epoxy? double sided tape?
Do these things even pop up for sale anymore?

It's mainly attached with screws (new holes were drilled). However, due to the spoiler being designed for the Euro bumpers & my car having the U.S. bumpers, some modifications were required.

Directly under the rear bumper it was designed to bolt to the body, but since my bumpers are not flush with the body it was screwed in by the wheelwells with some "custom" bracketry to attach it to the bumper shocks in the very rear(so it sits out further and lines up with the bumper lip).

I have never seen the rear spoiler before or after buying mine, but they must exist somewhere.
I have seen the front spoiler once on Ebay.de and the sideskirts on a seperate occasion, but the only rear I've seen is mine. I was lucky to get the kit 3 years back from a former BLAU employee and he had the entire kit new in the box. SCORE! Got it for $300 - shipped!

Good luck.
