I just recently upgraded my front brakes using the parts from a junkyard '98 Cobra (cost only $163). The parts list included the 13" rotors (stock ones are 10.8"), PBR dual-piston calipers, caliper brackets, bracket-to-spindle bolts, hoses, hose-to-caliper banjo bolts, and pads.
This is an easy bolt-on upgrade and you'll love the result. You'll have more stopping power and a firmer pedal feel. Just look for a '94-'98 Cobra and scavenge the parts.
The rear brakes can be left stock since most of the braking force is required from the front brakes.
