I've got Koni Reds and 250# springs up front right now. I've just installed them and I moved the perch as far up as I could by hand but I want the front end a little higher. The springs are 12' 250's and the spring starts to compress which makes it to where I can't turn the lower perch by hand. Is it fine to crank the lower perch up with the spanner wrench to where I want it or will this cause too much preload. Prior to the 12" spring, I had always used 10" springs and hadn't really ran into this.
