B13 ABS is a 1 channel system. If you pick the inside rear wheel up, the system applies the brake to the opposite front wheel. The B14 system is much better from what I hear. I don't have ABS on either of my cars, but I never hear anyone complain about the B14 system.MDmathNX said:Can anybody quickly tell me the differences between b14 and b13 abs. Specifically, does b14 abs suck or not?
