    Question Any Stabilitrak issues if lifting the inside rear wheel during autocross cornering?

    Do any hot-rodders/racers/car builders here know for sure what issues – if any- will happen with the Stabilitrak if I lift the inside rear wheel during hard corners while autocrossing? When I tighten and strengthen the IRS in my 2002 Eldo , I may opt for shorter shocks so that the shock is in mid-travel at the lower ride height.


    The computer would already know that this is the slowest rotating wheel in a corner, but after lift, it will be decelerating faster than the other wheels. I will not be applying the brakes during this condition, so maybe all that will happen the traction control gets turned on; and that might not be a bad thing…. But if it starts applying brakes to wheels to “correct” the condition or if the computer cuts power for a second or two as it sometimes does when I do a 90 degree corner at 30 MPG and above, then it will cost valuable lap time.

    This condition would not apply to racers in a stock class.



    Thanks

    I believe that is what will happen.

    See if you can find the threads/posts/videos by gdwriter - he extensively autocrosses a SLS in Washington state - he may have a bit of hands-on insight. Even PM him. he seems to push the car pretty hard and his many videos from many locations on and off the car don't appear to show any inner wheel lift in turns - at least not to the point of losing contact with the pavement.

    I'd worry more about front wheel bearing loads in these cars than rear wheel lift.

    ............ and, yes - if the car senses "wheel slip" or parameters outside a given set of turn sensor and/or wheel speed signals, then Stabilitrak kicks in with whatever it takes to attempt to straighten out the car. Disconcerting
