ok i'll be using type 1 irs in my split with modified plates
i wish to install twin pot brembo's
i have late 944 hubs-they have abs sensors-i think?
i know i need the seperate caliper mounts pre 85.5 944
and my question is,
in order to run these calipers do i use a 86 only 944 turbo disc
on my post 87 hubs with the pre 85 caliper mount
and,indeed do these hubs actually work in type 1 arms?
thanks in advance
are thes caliper mounts on any other porsche ie 912
928 ?? any ideas
