Thanks for the responses. Brad, I'll see what info I can give you without tearing the car apart. Single MC I believe is 19 mm (stock early 70's). Front brake pistons are 1 1/4" (rough measurement while still on car) x 4 pistons. Rear are stock M calipers (69' to 83' I believe) but not sure of piston size and they will be going away. No idea on pad compounds. I have an extra set but no markings on them. Is this good enough for a starting point?
And Mike, I like the idea of Carrera or Boxster rear calipers. Carrera calipers should bolt on to my SC swing arms? But the boxsters need adapters and a new MC? Price is a concern and I wish I had my original S calipers back.
Here is a photo of my fronts. If someone has input weather they are similar to 930 rears, maybe I have a direction to go with this. Brad's spreadsheet could also shed some light.
And, I'm close to being back at it. I've been working weekends for the past 4 years and tough to get a Sat or Sun off. I've been to about 2 NASA events in the past 3 years. But shortly, I will have Saturdays off so that's why I'm sorting out the brakes. Wish I could be at Sears this month.
Thanks,
Bob
