[s-cars] Big Reds (actually Blacks)

[Alexander van Gerbig]

    Nah the BIRA systems don't go down in the thickness they go up in the
thickness.  In System 2 the locating pins must be ground down 1mm per side
to make the clearance stock again.  There is no BIRA system that goes to
smaller thickness in rotors, that would be rather dumb and dangerous.
System 1 uses a rotor that is 1mm thicker than the standard Boxster rotor
(24 vs. 25mm).  System 2 goes 2mm thicker and so on.  System 6, the top
system, uses the Porsche disc and custom hats, personally I like that the
best.  That uses a mix of components, Porsche 993tt/GT-3 322x32mm rotors and
996 Turbo monoblock calipers.  How big is the 996 Turbo rotor?  Are we
saying the caliper shouldn't be used with rotors of different diameters?

    I mean 2B, Mov'it, and so on use a 30mm thick rotor with the 993tt
caliper which wants a 32mm rotor.  Those all seem to have a decent track
record and never heard of any failures.  Though makes BIRA seem tastier:)
