I have the Performance Friction dimpled fronts but they're sitting in my room. They don't make them for non-S size so you're out of luck.

I have Zimmerman drilled rotors and I'm not all that impressed. I installed them with new OEM pads, and do not do any heavy braking or tracking, yet all 4 of mine have minor stress cracks around the holes. The other issue I had to tackle is that the hats all rusted..bad! (area between where your wheels bolt up and the braking surface)
If you buy these, I would suggest using high temp silver paint on the hats BEFORE installing the rotors. If you wait till they rust (like I did) you'll be spending quite a bit of time sanding off the rust, priming and prepping them for paint.

If you buy the Zimmermanns, make sure you get the rotors with "Z Coat". This means that the rotors are dipped at the factory to prevent corrosion. Even the part of the rotors where the pads grip are coated and the instructions specifically state "do not to remove the coating before installation" - the pads will remove it.
With the Z Coat, you will find less rust stains transferred to your wheels after rain or washing, which is a big plus.....

Have the Zimmermans with pagid pads, I find the combination to be excellent, I have zero cracks around the drilled holes and had the factory coating applied as mentioned by Steve.

This past fall, I put Zimmermen's cross drilled rotors on my 964, along with new pads, and fluid. I think the car brakes better, but the old stuff was worn. I have no issues, but I haven't had them on long enough to develop any issues.

Thanks to all
Seems like the Zimmermans for the street are OK. As I said, I had them on my 911 and experienced no trouble. Some of you have had cracking problems and some of you have driven them hard on the track with no trouble. Curious!
Tire Rack has ATE rotors with a long curved slot not unlike the symbol for nukes at a reasonable price. They are under "Slotted and/or drilled high performance street" category along with the caveat, 'these rotors should not be used for racing or DE style track work'.
How how about pad recommendations for these type of rotors, I have heard that Metal Masters are decent and don't dirty up the wheels as much as stock. Any thoughts along these lines?

New Drilled Ones Installed
I just replaced last month all the rotors and pads. I do not track all, I just wanted a smoother stop since my Boxster has 68K on it. I purchased my parts from Pelican Parts, Balo rotors and Mintex pads. She now has a very smooth stop, it was a major difference. Rotors and pads plus I flushed my brake system...spent about $450. You do not need to buy caliper bolts. Use a good Locktight on the threads. The Balo's are German made and I compared to the one original ones that I took off...they were the same.

8s & 2s, I can't seem to find drilled Zims that are coated for my 2.7. I looked at Pelican and Ebay. Are they not available coated for drilled '02 2.7 or just not on the market right now?
