I bought this recently from my friends at Auto Perfection and I cant recomend this brush enough espec if you have the Pescara alloys with the R32 front brake set up. Previously I used the Megs wheel brush but this had some short comings for me namely the rubber tip of the brush would come after some time and the main body of the brush would depart from the handle which would pee me of somewhat but at the time i hadn't really found anything to beat it.....until now BEHOLD
It comes in two sizes small Grande!

Gets right to the back and some.
In the wee gap between my R32 calipers, nice soft brisles and worked well with my acid free wheel cleaner from AG, going to try it with some Bilberry soon.
A bit dearer at £17 but well worth it IMO
