Seen a set for sale today in related goods, just to let anyone else know I recently bought a brand new OEM set from BMW for £41.62. I then bought 2 x 82mm Carbon badges as I wished to go down the black/white route, however I could have utilised the exsisting blue/white badges. Little tip, if you are sticking badges on make sure you use the orange indicators as templates to asertain at what angle the badges are stuck on ! I did not and ended up with the BMW sign at 45% from the top
had to take them to bits and start again
