pinion angle change with LCA bracket hole change? have a UMI tunnel mount arm set at -2 degrees and UMI lower control arm relocation brackets set to the bottom most hole. The LCA already is at a sloping downward angle at stock ride height with COMP engineering rear shocks. i've had problems hooking up and am comtemplating bringing the LCA to the middle hole to help traction. should I try this? does the pinion angle need to be adjusted with a LCA angle change? also, would putting the car on 4 rhino ramps be a good way to level the car to get under to adjust the pinion angle? thanks

I believe the lower holes are slightly forward, as to not change pinion angle or your wheelbase when lowering the lca's. If you're looking for more forward bite, definitely lower them a hole and try it out.
Btw, are you saying the lca's angle "up" or "down" toward the chassis? I would think if you have lca relation brackets on there already, that they would angle "up" toward the chassis...yes?

The lowest hole will generally give you the best grab, but try the middle, maybe it's too much for your setup. The pinion angle will not change, as I believe the holes are drilled in the swing arc of the LCA. Im not sure though, since I made my whole suspension, and relo brackets, so I only have lower holes. Are your shocks adjustable? If so, try adjusting them, they might be the problem...
