Jay,
Since this thread started, I've decided to make some changes to my brakes, specificaly by upgrading to '94 E500 specs. I've purchased new front calipers & directional 320mm rotors, had the rotors slotted & cryotreated, and will run EBC Red Stuff front pads and Porterfield rear pads on the track. And Yes, I usually install new brake fluid within a day or two of tracking the car
