"But I really don't know why road use is ever a critera for kits like these. If you need a floating 365mm disc and monobloc assembly for road, then you're either a nutter or have some mentalist roads near you."
Well I think because most of the cars (on here anywayz) are used on the track as well as road in varying degrees. Ok, when pottering off to the garden centre for a few geraniums is the sole use of BMs finest, bbks border on the unnecessary and are a waste of money, but then so would a CSL be in the first place.
My reasoning was that the car will be used on a track, will be used on Welsh roads (and will be used to pick up geraniums) so I need all the help I can get

plus I'd probably get back what they cost on resale so like yours, having them makes a lot of sense.
