Kerscher rotor, 15 inch wheels.. what caliper?
 

hello guys,

i want to keep 15 inch wheels on my bug, pref vw 4 stud pattern.
im doing a rear disk conversion using a 914 disk and golf rear caliper, but wanted to upgrade my fronts at the same time.

ideally i wanted to use the kerscher disk (to keep the vw pattern) with vw disk, or vw drum spindles. i have both to choose from, both ball joint.

the question is, what caliper choices do i have to keep 15" wheels? i have heard of people using a rear caliper on the front? would a 944 turbo (4 piston?) rear caliper work ok with the kerscher disk on the front, and would 15" wheels be likely to fit?

other calipers iv thought about using are:
early 944 fronts, a golf front caliper, 933 rear caliper, a stock vw caliper spaced out, or aftermarket wilwood..

any opinions?
regards,
mabbo

The four piston 944 caliper is the same size front and rear, just the piston sizes are smaller on rear. A rear two piston 911 caliper might work, but IMO would go for golf. (since the rear is going to be golf)

i was a little concerned that the golf brakes front and rear would cause the front/rear balance to be out as a golf has all the weight in the front, or would the master cylinder sort this out?

Good point. I suggested the golf in front to keep the brake bias of the "factory matched" set-up. I would check the size of the golf m/c to VW m/c. You could always put a proportional valve in the rear line to get more rear bite.
