When selecting brake components be sure not to skimp on quality. Only the best will do. The brakes on the 1991 through 1993 models were quite undersized and are good candidates for swapping out in favor of larger rotors and calipers. 1994 onwards have large front rotors and calipers that work very well and are effective for most applications.
For road course applications adequate cooling is mandatory. This can be achieved with clever ducting, careful pad selection and cross drilled or slotted rotors.
Cross Drilled and Slotted Rotors
The idea behind drilled or slotted rotors is to offer passages for gases to escape which can increase the cooling ability and effectiveness of the brake. Not all rotors are created equally. Be wary of manufacturers claims of radically improved braking. Typical improvements are modest.
Larger rotors can definitely enhance braking performance. Such kits usually require different mounting brackets for the calipers and possibly different calipers.
The trade offs for pad selection are rate of wear, amount of dust produced and wear on the rotors. Many fritction compounds are available. Race compound pads typically are not a good choice for a street car since they typically require some heat before they reach optimal operating effectiveness.
Larger calipers can offer better emchanical advantage and more brake pad swept area. Usually new calipers will include mounting brackets. Offerings are available from Stillen (Brembo), KVR (Brembo, AP Lockheed), and Baer. A wider variety of pad compounds is also available for these aftermarket calipers which may be beneficial for road course or auto cross applications.
Wheel clearance is a factor here which cannot be overlooked. Be sure that your wheels have adequate clearance to accomodate larger calipers.
Steel Braided Lines
Steel braided brake lines will not necessarily reduce braking distance but can definitely enhance the feel at the brake pedal. Steel lines will expand much less than the factory rubber ones thereby increasing the effectiveness of applied brake pressure. Expect much better feel at the pedal, slightly reduced pedal effort and better modulation of the brakes. The end result may be reduced stopping distance due to the driver's ability to better modulate the brakes.
