Carl, a test drive will be available.

Warning:  Boost is addictive, just like drugs.  Once you get some, you just
want more.

I also have had good luck with the Porterfield R4S pads.  I understand the
pads come in 2 flavors, street and race.  I use the S flavor that is for the
street.  The initial warped rotors were a result of the stock pads used by a
novice driver (me) at a track school.  The rotors were turned but once
warped there is a tendency to return to a warped condition.  This happened
after 4 track events and I used the Euro floating rotors as a replacement.

At the track and on the street, my use of the Porterfield pads confirm
John's experience.
