Locker causing pushing in turns...

[Norm Peterson]

It'll probably corner OK as long as you're off the throttle while doing so - that will let the outside wheel overrun assuming that nothing is wrong inside the locker to make it behave like a spool.



On large radius turns, which includes nearly every turn at any race track bigger than the really small circle tracks, it shouldn't get too much in the way even if you are on the throttle, if you're going fast enough for the rear tires to be at much of a slip angle. Not everybody commonly drives this hard, though.

It's throttle on in small radius turns where the locker being locked by throttle-on that'll cause understeer. When the two rear wheels insist on turning at the same rpm exactly, the rear axle as a unit is going to try to keep the whole car going straight ahead, IOW understeer. Side note - this is why circle track racers use tire stagger, as a locker (when it's locked up under power) or a spool (all any time) will then naturally try to make the car turn left.

Lockers are a little like light switches. They're either locked or they aren't, and this can make for some sudden changes in cornering behavior if you're at at all indecisive with the throttle or use too much of it when you aren't going straight.
