I have a set (4) or NB1 Non-Sport Calipers, with brackets/bolts off my 2000 LS.
Fronts are OEM and rears are new non OEM.
I painted them high temp Burnt Copper.
I installed the Powerstop Z23 Evolution Drilled and Slotted Rotors, along with Ceramic Pads, front and rear about 2500-3000 miles ago.
I installed new hardware/pin bushing kits at the same time.
I'll add a better pic of pads tomorrow.
