Not too sure about brakes. Our brake wear was as consistant on BFG rivals as a decent set of take of HoHos... But this is a Zcar we're talking about.
Ron may be able to chime in, but we got about 4 hours out of a set of R4 Porterfeilds (Break in ,3 hour enduro and P then Q at Sebring.) There wasn't much left after that.
Now as far as hubs and bearings, I could see that as data has shown less cornering Gs on 180+ tires.
