Ok Guys, Here goes....
I've done the Volvo Girling 4 piston caliper x-over and here is what you need:
19mm master cylinder
Three VW brake line tees
Four 6mm X 203mm hard brake lines
Four VW bus front shock spacers
Two 4 piston girling calipers (240 series, solid rotor car)
new pads and hardware (for Girling)
You'll need to remove the brake proportioning valve and use a tee in it's place.
Use the brake lines and remaining tees for the front. The spacers will need to be machined down to properly center the caliper over the rotor. (sorry, you'll need to cut and test fit the spacers 1mm at a time for best fit)
Use your original 914 brake caliper bolts (or get new ones)
Put everything together and bleed like crazy. You'll have a little more brake pedal travel, but improvement in stopping is very different from stock.
The calipers fit perfect with original 2 liter Fuchs alloys (sorry, can't tell you if other wheels would work or not)
Pad overhang is minimal (about 1/4") but there is far more pad contact versus the ATE 320i caliper.
Good Luck and I must include that if you choose to embark on this conversion, this information is FYI only. If you crash and burn I nor this forum are not held responsible.
