I had Carerra calipers and rotors on the front and the stock setup in the rear of of my 73. I upgraded to the Boxster caliper in front and a BMW caliper in the rear. What I got was better feel. I was not having fading issues and overheating issues, I was looking to change the mechanical leverages. Because I have larger pads front and rear, I found I can get as much braking effort with less clamping force.

As my brakes would get hot later in a session, I would start to have issues locking the fronts, especially in bumpy braking areas. I also noticed that I was having to press very hard on the pedal. After making all of my changes, I was able to just use firm pressure and I still got the car to slow as I expected. This is on a 2100lb car with racing slicks.

I like the Boxster caliper, but I'm not sure if my rear application will work on the rear of a stock Carerra. I think you have a wider rear rotor. There was another thread not too long ago about someone using the rear Boxster caliper, but they were not happy with that setup and how the caliper was mounted.

Thanks my $.02
