I just installed H&R Sport Springs and Koni Yellow over the weekend. I used the factory perch setting which is second slot from the top for the rear and first slot for the front. it turns out the rear is higher than before... as for the firmness, i turned 1 full turn for the front and 1 1/4" for the rear and it was too firm, when i was driving on the nortorious interstate 10, i couldn't even talk smoothly. maybe the installer make a practical joke on me, he secretly turned the knob all the way......

donno, i think i still have a lot of turning to go.. any advice?
