no matter wat, do not put them on the highest setting. i did, and the ride was not even stiff enough. the switch ended up locking at the stiffest setting. koni rep said 2 things can happen, 1 i can use a plier and break it loose, or 2, it will snap off.
now my front shocks are leaking so koni's lifeteime warranty will cover it. just don't put them on the stiffest setting. they knew about the problem, just never told anyone.
