I am still working on my new project car( used and sold as RTR) uh, yeah! anyway, was'nt sure how to shim front upper arms. Got two sets of shims, 4 o's and 4 clip ons per side. Any recommendation as to the application. Should I slide the arm forward and shim it that way, leave it in the middle and shim front and back? Obviously there are tuning options here but I am just looking for a common sense baseline to get up and running. I really need to locate an owners manuel but have'nt found one yet, so here I am. Thanks in advance, nothing but the best from you all!
