I am aware that the Sierra RS500 has had a modified rear beam of which for race preperations there was a modification on the beam, using trailing arms. I'd like to know or see a picture of how they where mounted or maybe if you lads know someone who can craft or machine these mods.

Cheers

 

They were for show only really mate. there were two extensions welded on. You can see them clearly in the shot of my spare beam in a van.

 

here is a close up shot of the added brackets, they use the same hole as the normal arm and are just tack welded on the other side. As Andy said these dont have any function other than to provide an outline for the race ones to be made to. The beam itself is a standard 3dr one on the road 500s.
