i am in the middle of installing eibach pro-kit spings on my bilstein shocks and i was wondering how tight to put the top nut on.

At the moment i have the spring compressed and the nut tightened on top with about a half inch of threads of the shock shaft coming out. I cant seem to find any torque specs for this nut and it does not seem to get any tighter..should i keep going until the thread stops or what?

 

That's how far I went..all the way will the nut runs out of threads.
