The FS has a discs/calipers upgrade from the 4-cyl car. Much easier to use than the 3-cyl setup without vacuum.

I've also heard that you can simply puncture the diaphragm in the booster reservoir (drill through it), and it significantly lessens the amount of pedal effort required. Not sure I totally buy that idea though - not enough to try it on the FS anyway (in case we ever want to add vac assist).

Ben: I can attest to the insanely hard brakes without assist in my '98 3-cyl.
