Most certainly the Boxer -design, side panels, thanks to Scurrel who put me on to them when I asked the same question a few weeks back.
Cost £110 plus paint, but they are very well made, fit nicely and look great.
I have just painted them my self, using BMW aeresol and laquer, as I did six months ago with the rear hugger, You can get a really good finish for about a tenner.
good luck, and Merry Christmas to you all
