On our 2004 Harris round tube car we run the 15" lower and 17" upper on the left rear. On the right rear we run equal lenght z-link bars, both 20 3/4". we just leave the four link clamp bracket off the frame on that side and use the normal 2 link mount on the front.takes alittle of the steer out of the right rear and calms the car down a little. We ran this setup on the big half mile tracks and it hooked up real good and drove quite a bit better.

most popular is 17 upper 15 lower, or 14 upper 12 lower, i run 20 lower 16 upper, but i like being different.
on the z link most cars about the same front and back, some run the front shorter(rayburn style swing arm). but most cars are about 20 each.

Ours are about 14.5-15 lower and 16.5-17 upper on the left. Right is the same on the z link. then if you want to run r bar RR you can flip the bar over and be close to the right length.
