Brembos, big reds, etc.

Personal opinions on brakes. No flames please.

I have done a little research on the latest moves  by members to put 4
pot boxster
brakes on a 3500+ lb car (200's, 5Ktq,s, etc.) Even a A4 Quattro is no
lightweight.
This caliper is about the size of the rear brakes on a 993.
Kind of pint size.  Not only is the square inches of pad surface small,
the heat sinking capabilities of the housing are small, and the clamping
force of the caliper itself is small. This Caliper would be suitable for
a small FWD coupe like the GT, or maybe at worst case a Ur-Q. I realize
they are cheap, but if you are trying to get a reliable increase in
stopping power, especially if you are using them on the track, you are
going to wind up at the end of a amateur brake engineer failure test.


A8 Rotors, S6 Rotors are decent stock rotors, but they are not even in
the same league
as the Porsche Rotors used in the 993  front and 993TT front.

A4 and A8 owners have experienced severe rotor warp with only a day on
the track.

Big reds. Seems to be two different Big Reds. 993, (351-421-00) and
993TT (351-425-10) There is a 24% difference in pad size, let alone
differences in piston and housing size. It all counts.  Compare these
calipers to the Boxsters, it is a world of difference.

Just because you can make'em fit, does not mean they are right.
