Here is what i run as a basic setup on my z-link. 15" links with the lr lower @ 17 degrees and the upper @ 4 degrees, rr lower @ 15 degrees and the upper level. Torque link @ 18 degrees.
I imagine that with all your links virtually level the car doesn't lift under accel unless you run a very steep torque link angle.
Adding angle to the lower links will make the car lift under power and by having the lr at a different angle than the rr there will be an effect of adding wedge to the car under accel.
Ideally you want to adjust the lower links for different track conditions, but this is hard to do at the track with the springs mounted on the links, not only does it take extra time but its also hard to get the wheel weights back the same. For the sake of ease and time i will usually move the torque link laterally to the right to decrease the amount of wedge that is added under accel , or i also have mounts for longer upper bars (32") but i only use those when its really tacky, and as of late most of the tracks around here are pretty dry, and i have found that adjusting the torque link along with wheel offset and stagger changes have been the only adjustments that i have really needed to do.
The only real issues that you need to be aware of with adding angle to the lower links is that it adds roll/ride steer but on virtually every z-link i have seen its still a pretty minimal amount. Also it makes the handling vary more with roll/ride but again its pretty minimal. My driver still says that this car is the easiest car he has ever driven and is very consistant lap to lap.
Btw, congrats on the win at charleston earlier this year, looks like you've had a pretty good season thus far.
