Message	Z31 bearings are more durable because it is a harder material (aluminum), but it is less tolerant of dirt. Z31 bearings are harder on your crankshaft if you don't change your oil often enough. The Z32 bearing is softer, and because of this it is more tolerant of dirty oil. Neither bearing will be a problem, provided your engine is properly tuned and the oil is clean. The Z31 bearings are more tolerant of detonation.
