Has anyone found a good deal on an OEM or afermarket RS style spolier? I'd like to bolt one on my '09 TT but the best deal I've seen has been north of $600.

The AofA website has one listed for $525...That's south of $600, but not by much...

The AoA accessory spoiler isn't exactly like the RS spoiler. There are 3 posts instead of 2. On a brighter note, you can now buy the spoiler pre-painted to avoid body shop paint expense.

Thanks for the ideas, it looks like the price has come down a litte. I didn't see the paint option on the site, but that would definitely be a plus.

If anyone has gone this route or has added an aftermarket spoiler, It'd be great to see some pics.

I've been looking but haven't made a purchase yet. Here's a place that has the TTRS wing:

That's exactly what I have in mind, I just wish I could find it at a better price.
