I just got my reply form Wendy at Porterfiled for my application (smaller SVT calipers)

Ok your pads will be a part number
AP 648 R-4 $169.00
The R-4 is our full race pad that can be driven at street temps. Although if used as a daily driver you will only get about 3000 miles out of a set of R-4 pads. They are just not designed to last long at constant cold temps. They will though preform very well on the track.

You could go with our performance street and autocross pad but it does not hold up well under severe track conditions. They are AP 648 R4-S $89.00.
