My thoughts...

If you want a street pad that will also work for the track, then I'd recommend EBC Yellow. They won't make any noise on the street but may not hold up if you are truly running front of the pack Spec Boxster lap times. They are more affordable than Pagid. They might work well if you're only doing four track days per year and the rest of the driving is on the street.

If you want a track pad that will also work for the street, then as Trygve suggests, I'd also recommend Pagid Orange. That is what I currently run on my Spec Boxster that is driven on the street. The pads make some noise but they don't squeal like an 18-wheeler at every stop sign. These pads will provide great track performance but are more expensive.

To sum up:
Street friendly, affordable, good on the track: EBC Yellow
Great track performance, some noise on the street, but more expensive: Pagid Orange
