I've had the lock rite for about 20 years, all street use(okay some dirt). Most of the time I forget it's there. Tight corners it makes a soft clunk-clunk-clunk sound. On a freeway overpass corner I decided to punch it and the car stopped turning and went straight toward the concrete. Basically shat myself right there. It's a completely on or off thing, it doesn't have any slippage at all.
