Forgot...going too high in performance will have some liabilities you will need
to consider and manage
I went with Performance Friction carbon when they first came out. He's a buddy of
John at Praise Dyno Brake. Both used to work at, think IIRC, Holly or some such
Anyway, they were GREAT when hot, but when cold...slide right through a cross
walk in front of an elementary school. Lucky very early and if later...it might
have been filled with kids
Friction material *ALL* have a working temp range. The higher performance they
are, the higher the lower end of their working temp range. Those good at the lower
temp range will have a lower high end range. Some mix and match to try and get
a wider temp range, but a compromise at best on the ones I've tested
