alignment/original shim thickness/lowered
OK, I hate to beat a dead horse, but here I am with my whip. So for starters. I have a 1996 impala ss that had HORRIBLE tire wear issues but drove like a dream. All tires, front and back, would wear really bad on the inside. I took it in for an alignment, I feel they did not do a great job and frankly didn't care. Tire wear was still bad and I had really poor handling. So, I have rebuilt the front end (new front Moog UCA, MasterPro/O'Reilly LCA, 5/8" GM spindles, bearings, bump stops, Eibach springs, Moog sway bar link). Reasons for these new parts: driver's side spindle damage, tire wear issue, wanted larger ball-joints.
Perhaps I have not searched well but I am wondering what is the total thickness of shims that should be used, keeping in mind the Eibach springs. I know that I must remove 0.30 for every half inch of drop. Also, what does the FSM mean, what exact spot are they measuring, when they mention "trim measurements"? Is it the top of the trim panel that runs along the bottom of the vehicle? (that is what it looks like). When I was removing my UCAs, the shims all fell out before I could keep them intact, plus they were totally wrong anyway. Forgot the alignment specs from previous alignment.
I have seen various specs for alignments. I am hoping to receive more feedback on this. I have stock dimension aftermarket rims, stock size tires, and I want to achieve great handling without having to sacrifice tire wear. Thanks again for any information. (Sorry for the novel.)
