Not available in the Coupe size (305x28) and don't include the centre bell, which will add another £150 - £200 to your first purchase
Far easier (and not much more expensive overall) to get hold of a pair of Fiat 500 Abarth EsseEsse floating discs, which will fit straight on, as long as you have aftermarket hub flanges
I just got a quote from KSport for front brakes in standard size, not sure I will be getting them at £895 plus shipping and a long lead time. Probably not bad for calipers and discs however. They do floating discs with 8 pot calipers but smallest size available is 330mm and I was considering leaving standard wheels so that is no use.
seemed reasonable for larger brakes until you add shipping and the possibility of import tax but I am not sure what you are after or willing to pay
They did seem quite professional and replied really quickly they also have stuff on ebay which is listed as £8 postage and item located in the UK but i did not see any listed for the Coupe Im thinking of going for a decent set after Christmas if no Alfa GTA kits come along in the meantime!
