Did you ever get to the bottom of yours pulling left? I have this problem on mine and its driving me nuts, I've changed both wishbones, both ball joints both drop links and both track rod ends been on hunter system 4 times this week and went to ats, so that's 5 times this week with no fix to pulling left, I did motive the other week that I had wear marks on my passenger side drive shaft, mine has been lowered on standard shocks with h&r springs, not sure how much it's been lowered tho.
i just wondered if you ever got to the bottom of your issues?
