Thanks for the intel gents.

 

I installed the RD Sport rear spoiler on my previous car and the fitment wasn't that great. I traded it for a 550i and I installed the M5 trunk lip replica spoiler from Trinity and I'm satisfied with the fitment and the overall look. When it's all said and done you should install what you like, but as one of the members indicated, don't glue it on because you might change your mind one day.

 

Which one is pictured on your sig car? Do you have any detail shots of the spoiler? Thanks.

 

I finally got around to installing the AC style spoiler I bought on eBay today and as I said previously, the fit is perfect and so is the color match. It came with alcohol wipes, 3M moulding tape already installed, a small tube of adhesive promoter and a tube of silicon adhesive along with 2 q-tips.

It took all of 15 minutes to do, including washing the section of trunk, marking the location with tape while holding it in place, applying large dabs of silicon adhesive on the spoiler between the adhesive tape strips and a very thin coat of adhesive promoter prior to pushing it on into place. You need a second set of hands while lining up each end using the tape as a guide and then push onto the trunk and apply pressure along the entire length of the spoiler to get good adhesion. We held it in place for a few minutes while the 3M tape adhered to the paint for good measure. It was solid!

Here are a few pics for your viewing pleasure.

 

Thanks for the pictures! Looks great!
