I'm going to get the my Bells copied after then seem to work rather well. They remove at least 2kg per corner.
They can carry a 288 disc (standard), a 295 disc (standard AP + spacer = the AP upgrade size) amd a 308 disc such as the ones i have on my car now. (See my Project JG thread)
Reyand can supply the discs and they are going to make the copies too.
I've not got a confirmation on price yet but expect it to be around £180-220 a pair if there are 5 people interested. further discounts availalble if more people are interested
They will come anodised and be available in black, silver and gold (:
A whole car solution will obviously need two pairs (for which you need two entires on the list)

I may take more and then place them in the shop and they can become a Mango Bell
