s4 and 930 brake upgrade
I have a set of 928s4 front calipers and 930 rear calipers. I know someone has adapted these to a 83 911. Can someone tell what I need to get these on my car. Thank John

Here is what you need:
Front caliper adapters
Front 930 rotors (there are two versions)
Mounting hardware (bolts, washers, spacers)
Front SS brake lines
Those rear 930 calipers are poorly biased for the big 928 S4 ones. You need front 930 calipers converted with rear 930 bridges for proper brake biasing
930 calipers must be machined and modified to install on an SC
Mounting hardware (bolts, washers, and custom spacers)
Custom brake lines from caliper to flex line
930 23mm MC.
