The easiest and cheapest way to add more stopping power would be to buy aftermarket pads, lines, fluid, and maybe a rotor from Braking Performance, sold through the Chaparral catalog, and other places. If you want to spend more money MAYBE Performance Machine makes a 4 or 6-piston differential bore caliper or caliper-and- rotor kit. If you want the stock look, check an see if the wheel has the bosses and threaded holes on the opposite side of the wheel that the disk is on now. Most times, if the wheel is used on similar (usually larger-displacement) models, both sides of the wheel will be drilled and tapped for dual disks. If the bosses are there, but no holes, a good machine shop can fix that for you. If you're really lucky, maybe the other fork leg will even have the clearance holes for mounting the other caliper. You might check the junk yards and see if you can' buy the fork leg, caliper, and rotor from a model that will fit. Plan on new fork tubes, however, as most in the junkyards are pretzeled. Good luck.
