Alright Mr Honet,
I have a set of Braking Waveys on my VTR..
I think they not only look great but coupled with a full set of braided hoses they perform brilliantly.
I got mine from Carbontek Racing -they are now based in Redhill -and you may have seen some of their bikes in the bike mags -they do all sorts of specials like -turbo Hyabusas in GSXR1000 bodywork..

I think a rear wavey disc is a bit redundant as no-one really uses the rear unless it's a hill start!...more show than anything else.
I think they're about £150 each disc -but if you were to order a full set -front & back you'd probably get a discount.
..by the way they don't cause any more pad wear than normal brakes- anything you read to this effect is bollox.
