[s-cars] Big Red question

[Linus Toy]

Ok...different tone from my last post :)

I've got BR calipers on RS2 brackets over 323x30 (A8L rotor).  Rotors were
cryo-treated, no drilling, no slots...this experience may or may not compare
for you.

Mintex Red Box:  quiet, good cold "bite."  dusty, but not dirty.  With this
setup, I did have a resonance at about 35 mph from the rotor...not sure why,
but only with this setup.
Porterfield R4S:  quiet, reasonably dust-free.  "bite" not as good as with
Mintex Red box.
Porterfield R4 (track only):  noisy on the street (getting to the track) but
who can tell on the track? :)  dusty, dirty, but that was from 120 miles hard
use on the track.

Are your rotors the same as before?  Have you checked your hub surfaces for any
corrosion or dust that might put your rotor a bit out of alignment?  Not sure
what you mean by shims--where?  Between caliper & bracket? Or bracket and
strut?  How might this help?
