Alright, finally got around to some trial & error runs. Took the trunk liner out for a couple of hours yesterday (which is a b*tch to put back in) and made some minute adjustments.
Settled on this for now and it feels pretty comfortable without sacrificing responsiveness. I do, however, still have this vibrating sound coming up through the dash when I go over brick roads and some sharp bumps. It annoys the sh*t out of me. Any thoughts on that?
