Porsche brakes on 1303

[flat]

The front setup works, but you can machine the OD of the early 944 hub down and then mount the Boxster rotor over it. You will need the longer studs from a 87+ 944 front hub. This way the Boxster pad will match better with the larger rotor.

For the rear, the 993 rear disk is too shallow and the brake shoes will overhand the braking surface. The C2 calipers will bolt up perfect with 986S rear disks, or 86 944T disks with a 3mm spacer to center the caliper.

Thank you for the info.

It seems that the 964 rear 2-pot calipers are more difficult to find than the 964 or 993 rear 4-pot. I may use 964/993 4-pots instead. Will 16" fuchs acommodate to the 4-pots?

Which master cylinder should be used for 986 Boxster front calipers and 964/993 rear 4-pot calipers, 944N/A m/c or Beetle stock m/c?

C2/C4/993/944T rear calipers are interchangeable. 16" fuchs will clear but they have to have the '951' part number (more room behind the spoke for caliper clearance). The '911' pn wheels may require a small spacer.

4 piston brembo brake setups behave quite well with stock 19mm dual circuit mc's.

I have a set of 911 turbo 16" fuchs (7" front and 9" rear). Most likely they won't clear the brembo calipers without a spacer!
