Another possibility for a semi-modern set up could be to use the Scarebird set up
but with different calipers. By this you get the 11.78 / 1.25 discs combined with either
the single piston 1999 Dodge Ram caliper, or the 2 pistons Dodge Ram Caliper or the
SSBC caliper with two pistons aluminum design. I just can΄t find anything about the bore
diameter of the 2 piston OEM Dodge Ram caliper. The single piston has a bore diameter
of max 2.75. The SSBC has two 2.126 pistons. So the piston area is 5.94 (single) vs. 7.1 (two piston).
Calipers from SSBC, seems to be a 1:1 replacement.
