After a few track days, I found that brakes are the first thing to go, so I beefed them up a bit:

Porterfield R-4s pads all around
Goodridge stainless lines
ATE Blue DOT4 fluid
R1 Concepts drilled and slotted rotors

I noticed better feel, a firmer pedal, and hopefully good fade resistance, I haven't had the chance to give them a good run yet. Still breaking them in. I still had the original fluid in there, after 62,000 miles....ouch.
