I highly doubt it is the SETTING of the car that will give you 180.....kicking out 180 is definitely either something in transmission department is binding, broken parts or your tires is not gribbing the surface due to unglue or splitting.

I had similar situation occured on outdoor parking lot, and indoor carpet track. Once I sees the car doing this, I always found 1 of the rear tire's sidewall are unglued. Happened almost all the time in every cases.
