Don't bother with Sport Chrono, it's a waste of money on the GT3. All it gives you are some memory and timer functions. The "Sport" button is standard on this model and it gives you all the engine, exhaust etc. functions so why bother. I originally ordered the option too but deleted it after learning the above. The PCCB question regarding rotor chippng is true. Porsche supplies steel rods that you screw in the lug holes so you "slide" the wheel on and off without hitting the rotor. As far as whether you should order PCCB's, the track guys mostly run steel because it's more cost effective. I ordered them because when I went to the Porsche PDE driving school the cars had them and I was very impressed with them. I would think that in 5 years the cost of replacement (which is very high) would be an issue for a prospective buyer. If your concerned about that order the steel brakes, the are great brakes too. Many thanks for the input. I went with the steel brakes due mostly to replacement costs ($5400 versus $500 per rotor) since many used 996 GT3's here in San Diego are used as track cars.

Ordering the Bi-Xenon and sport chrono. Can't decide on PCCB's. Are they still prone to chipping when putting the wheel back on? Is the unsprung weight savings mainly felt on the track? Will they be an asset or liability 5 years from now when I sell the car to a serious track person? Jim
