Dual-use pad compound preferrences

I just picked up my first Boxster. It will need new rotors and pads soon, and I'm trying to figure out which pads I should go with. The car is my daily driver and will see several track days every year. Ideally I would buy pads that are suitable for the street and track, although realize this my not be the fastest track setup. The car will have high-performance street tires on it and OEM suspension. What pads should I be considering? I've used Pagid Sport Blues in the past with good success, although think I need something with better fade resistance. I've also used Ferodo DS2500s which hold up to heat better, but am still not sure that compound will resist heat well enough for track usage. Am I just out of my mind thinking I can use one pad for both purposes? I realize there are compromises to be made.
I'm particularly interested in Hawk pads, as I get a significant discount on those. Which compound should I look for? Any words of wisdom are greatly appreciated.

You're asking which is the best compromise. But, why do you want to compromise on your brakes?

Buy a set for track and a set for street.

It takes about 1 hr. (or less) to swap the pads, and the Track pads will have ample time to bed-in on the way to the track. Plus, it gives you the opportunity to inspect everything and make sure the wheels are accurately torqued - a good idea when running high speed.

Using too agressive a pad on the street will cause stopping performance to suffer until the pads are well heated and raise the likelyhood of squeal. They will also eat through your rotors much more quickly just for the sake of a few annual tracks days.

Cheers!

To save time and money.
As this is my first sports car, I am eager to learn about this sort of thing. I do, however, have extensive experience with my previous car, an Audi A4. That had more power then the Boxster, WAY more torque and weighed 300 pounds more. I also had r-comps on it, all of which added up to a greater strain on brakes that what the Boxster has. I spent many happy track days with DS2500s and left them on year-round. My experience tells me I can do the same with the Boxster.
That said, I AM a Boxster nOOb, so I figured I would ask here. Of course, one can always get better fade resistance with more aggressive pads, but if you're not boiling fluid or getting fade, what good does it do?
In case you can't tell just yet, I enjoy playing devil's advocate. I hope it doesn't sound like I think I have it all figured out based on my hp/tq/r-comp statements. I'm just trying to provide as much info to the forum as possible in an effort to find the best answer. I'm 100% open to hearing all thoughts.
For the record, I am leaning towards two sets of pads, but think there is at least a chance of getting away with one good set, provided it has just the right characteristics.
Thanks for the response, Lil bastard. I've enjoyed reading your posts in the past and look forward to what you and the others have to say after reading this.

Thanks Pat,

Not to diss the Audi, but Porsches are known for their brakes and the Boxster (base or 'S') has some of the shortest 60-0 distances in all of cardom.

But, they're expensive as well which is why I'm not a fan of running agressive pads on the street to accomodate a couple track days. The wear to the rotors the other 363 days will exceed the cost of a 2nd, dedicated set of track pads.

I cannot accept 'saving time' on a track car. IMHO, a car should be prepped for the track, both to maximize enjoyment and safety. It takes me about 90 min. to prep mine which I honestly don't think is too stiff a time penalty considering the penalty, both in treasure and blood, somtimes imposed on a driver with an ill-prepared car.

When the proverbial sun sets, it's your car and your money. If you think it's a wise course, stick with it.

Cheers!

You can get the OEM sport pads if you have a S.

997GT3 Brake Ducts are also a cheap upgrade for better brake cooling. You can also get 2-piece rotors from GiroDisc or Performance Friction as well that has very little(if any) negative effect on the street.

Thanks, ekam. Yes, I do have an S model.
The site says, "Not recommended for street use." I wonder what compound it is.
When my rotors are ready to be replaced I plan on going with the PF two-piece rotors.
