Here's a lame aerial of all three cars. But most of the work gets done on the one in the middle.

With my brother in town I was able to get some brake work done on the SPEC car and Boxster.

We flushed the Boxster's brake fluid. After three track days on the two-year old fluid it was well due. The pedal feel was probably 10% firmer.

On the 944 SPEC after miserable brakes, I ordered some Hawk pads and ATE Super Blue. With both installed, the car now stops like a race car. What a difference. It must be on the order of a 50% increase in clamping power.

I would have taken pictures of the above procedures but if you need help with them, or pictures from me, I suggest you take your car to a mechanic.
