nice ride height and stance.
have you checked the lock to lock count and seen if the rack is centered that way regardles of whether or not the steering wheel is also centered at that spot?
when you look straight down from above or straight up from below, with the wheels straight ahead, do the tie rods go in a straight line from one side-through the rack-to the other side? sometimes the rack used doesn't mount up with the same spacers as the one the rack mounts on the crossmember were designed for so the rack is spaced too far forward or back from that straight across line from the outer tie rod connection at the spindle hole on each side. the tie rods and rack should be inline with the spindle mounting holes for the tie rods. you could run a string line from side to side for a quick check if a visible line of sight is awkward. theoretically the outer tie rods should also be the same length from the pivot points as well.
heidts used to have a tech section in their catalogue that had a write up called understanding independent from suspension. maybe if you contact their tech line they would be kind enough to send you a digital copy or link. good info in there. I have a copy on my desktop but am away from home currently. sorry.
