If you keep stabbing the throttle coming out of a corner like from a stop sign like I think your doing
, your going to have this problem with most any limited slip diff that uses clutches. It will always spin the inside tire. All you are really soing is burning your clutch packs. If you keep doing this you will eventually be stuck with one wheel peel. That is why if your are going straight both tires spin.. You diff is still working. Track locks are supposed to slip around corners, thats the whole point.
