Searched for this couldnt find answers I need....

I have a set of Tein's Control Master Type Flex's. I want to raise my car a bit because I've noticed that one of my tires has been rubbed out to a point where the aluminum threads are sticking out, and my wheel-well is a nice polished aluminum.

1. Do I need a torque wrench to lock the lower barcket? or can use regular wrench?

2. Are there any guidelines as to ensure that I lower all sides evenly???

Because a few people told me that they just count the number of times they turn the adjustment bolt. The manual as broad as it is,seems to imply measuring with a ruler. Please give any feedback. Thanks guys.
