While I had my heart set on wilwoods, I've decided to use the OEM brakes until such time that I NEED more brakes or I have money to burn. Perhaps those members who have been racing subarus can chime in.

Any aftermarket slotted rotors?
What fluid?
What pads for street/race? What about swapping pads for the track?

I'll do some research tonight, but wanted to post up before I forgot
