Seen these badges on e-bay and bought them, brand new, an impulse buy, but i have them now and i like having them. As far as i know these aren't available from a dealer without proof of xkr-s ownership, all i need now is the car

 

I had thought about finding the R badge for the front grill

 

No problem, here's one, it's the more up to date one with the circle R, you can get a matching rear one also.

Keep in mind though this version does not match any of the other R emblems such as steering, shifter, brakes, seats, rear hatch, dash, etc. I made my own using the hatch emblem and a screw with washer to hold it on. Hasn't fallen off in almost a year.
