IMO, the biggest downfall is the rotor diameter, so if you are going to spend money, spend it on a total aftermarket system that uses a stock spindle.
If you are going to keep the stock front rotors, go with good aftermarket pads first and just replacement calipers. Upgrade to stainless steel braided flex lines front and rear. If you are keeping the vacuum boosted system, upgrade with the b-body 12" dual diaphragm vacuum booster and a right hand drive 2000 S10 1.0" bore master cylinder (must be a right hand drive S10)
This master bolts right in no mods and actually works AC DELCO Master Cylinder Part # 89056529 or 18M974 (same master)
