The Alfa Romeo Brembos are the same as the Fiat Coupe ones?
Nope the alfa's 166 are bigger.
Went to a mate this afternoon who had 406/fiat brembo's on his mk1 Cup.
I test fitted the Espace calipers on the 172 and he said it is NO problem that the pads are a few mm shy off the disc.
He judged the difference(with 280mm discs) and said that this is no problem, this guy is a certified Renault Mechanic and the only one who is allowed to work on my car except me
You only have to use some washers to get the spacing correct and job done.
He also mentioned that there are cars out there that come out of the factory like this (pads a few mm shy of the discs).
I'm going to sell my set of calipers as im going with the Alfa brembo's so if anyone's interested (with brand new Brembo pads).
