Looking for a starting point advise for anyone who has/had the Star kit on their Apex.
I installed the kit WITH the Doo stiffer center spring. Question is, how much preload to put on it?
I'm gonna go with quite alot, like little to no threads left showing and can always easily loosen it some if recommended by anyone here with solid advice.
Thanks!!
