I called Nalley today to get a quote for the above. They appear to be stick-on emblems, not a vent or who knows. With the forum discount, the pair were about $205 shipped. I passed this time, I may change my mind in the near future. My thoughts were to place it above the repeater and Remove the R badge below the repeater. Just wanted to pass on the info as a lot of you have changed your badging around.

 

Saw a newer xk r the other day and they have a much nicer 'R' type badge on the back. It's the same as ours but without the shiny, silver part so it looks more clean and modern.

 

I have 3 of those I bought from Nelley a few weeks ago...They're $8 each but you only get free shipping (within the US) at $25, if you get three, they'll charge you $25 even and ship for free...

Here's some pix of that emblem on the S-Type:

I like the idea, but that thing looks too big for the side of the STR. I opted for the "supercharged" emblem on the license plate frame. A whole lot cheaper, and looks decent.
