Prevail

Alright, so earlier today I spent a few hours with a sawzall/dremel/grinding wheel and finally ground down my bushings enough to slip my EK-meant Tein RA's over the rear LCA's. So now that they are on I have a few questions:

The rears seem to be clicking. I went over a bump and watched them and sure enough, the top end of the strut assembly pops up a little bit from the pillowball mount and comes back down with a clicking noise. How can I fix this? I think that perhaps I didn't tighten the nut on top of everything down tight enough.. will try that later, but any suggestions would be great.

What is the best way to measure out the best height for everything? I want the car to be level, right now its a bit lower in the rear.. any methods for adjusting everything? I'm thinking of just busting out a tape measure and jacking it up, adjusting, lowering and measuring over and over.. but any other methods would be appreciated.

Which way (up or down) raises/lowers the car's body in correspondance to the spring/perch assembly?

Thanks~
