The issues with swapping out the brakes to the "Big Red" brakes that came out on the "S" model can get expensive and require modification to your car you may not need, or want. I was tracking my '99 Boxster and wasn't happy with the OEM brakes and had 2001 S Big reds installed. The rear axle housings (knuckles) have to be changed to S housings so your emergency brake will hook up and work, otherwise you are without one. The S housings are larger in diameter so the ABS sensor module will not detect the rotating axle, which is smaller in diameter to an S axle. You can also change the axles out, which gets really expensive, or you can do like my mechanic did and and make an adapter that holds the sensor further down into the housing so it can see the axle rotating. Your rear wheel bearings will be larger and have a sensor built into them which translates into more $$ when they have to be changed. My entire conversion was $1,500 which was a steal at the time and the larger discs and calipers really make a difference in track use, and street as well. It is one of the best mods I've done to my '99 but you will spend a lot of money and have a car that no longer has the period correct parts as well as having to align the rear which no longer can be done by inputing the VIN into the alignment equipment and getting OEM specs. There is a lot to it and if I hadn't been tracking I would have painted the calipers red and put cross drilled slotted rotors on. Great color choice BTW and if you do decide to sell those wheels pm me, I'm interested.
