Guys am i right in thinking the s4 and 320mm brakes share the same caliper just a different carrier?
Thanks.
I know a lad on here so time ago fitted carriers from a a3 3.2 v6 which had 345mm discs and had the same issue as you have just mentioned.
Shouldn't be an issue if using the 320mm calipers with s4 carriers though, as Rob said there the same caliper!
Well im now at a loss, martin has very kindly measured his 320mm carriers for me and the fixing hole to slider measurement is the same as the supposedly s4 brakes i have here.
Is that possible? Could it be the depth is the same, its Just the height of the carrier is different?
