^ Did you read the article in Excellence about the BSX and BSR? Maybe this is a good question for the author. Maybe they'll print your question.

@Perfectlap - You just reminded me that I have not received the Excellence Magazine since I moved - I should probably change my address. So no, I have not read the article and I am looking for a quick decision so I can install them before my next event.
@Topless - I am not sure what your recommendation is but I read it as ' buy the cheapest ones because they won't last anyway'. BTW - I did install the GT3 brake ducts.

I still have more questions than answers. My Balo OEM quality rotors were dirt cheap at around $40 ea. Zimmerman are OEM quality for around $80 ea. and many Boxster drivers say they are better than Balo. Genuine Porsche rotors are around $150 ea. I got 17 track days on the Balos since last May and they were pretty good until this weekend so I shouldn't complain too loudly. The guys I know who have tried the high tech/ high$$/slotted/crossdrilled aftermarket specials have complained about cracks forming the first weekend out. I have no personal experience with them but brake safety is a biggie and cracks are bad news.

I guess my preliminary recommendation is to buy OEM quality and really "Sunday cruise" your cool down lap. Experiment with pad combinations to find the right setup for you.

Here's another company that somebody recommended to me:

http://www.frozenrotors.com/

Apparently they are expensive but last a long time. Has anybody used them?

I would think slotted and/or drilled rotors would make the problem worse rather than better. You want more metal to hold and disperse the heat rather than less metal.

I thought the cross-drilled holes' purpose was to ventilate the brakes?

OEMs cross drill to save weight ... cooling happens through the gap between the two sides of the rotor.
