I have beat on mine with a sticky street tire and auto crossed it running many laps last year. The launch is definitely not like a drag strip and slicks, but it has not given me any trouble with a stick and 4K RPM clutch dumps. Almost 8K miles worth in 2017.
The Tru Trac is much more drivable in an auto cross environment than a locker.
I am not sure I would use one in my drag car, probably stick with the spool or locker.
