I just talked with Steeda and they said their top link will be available in a week or two as well. So the lower arms only helped out a little? What's involved with installing the top link? Sorry for the lack of knowledge, but I'm not even sure what the top link controls or what it will improve. I take my hat off too, because when I was at the line, I just wanted to stomp on it. I'll eventually get more comfy at the line. We'll have to meet up there some time!
M1Rifle-I understand what your saying and please correct me if I'm wrong, but my thinking is more along the lines of the following: Shifting into 4th could hurt you more depending on the power you have at that specific rpm-knowing this by looking at a dyno curve. I don't know for fact or anything, I'm just thinking logically. I new to studying dyno curves and running at the track, so I'm just asking questions, not debating.

169Stang,
Both the upper and lower arms are involved in limiting axle-windup. During hard accelleration, the pinion gear is actually trying to "climb up" the ring gear. This causes the rear-end to try to rotate upward, opposite the direction of the wheels. The control arms are designed to allow the rearend to move up and down and to tilt left and right but not to rotate. The rubber bushings in both the upper and lower arms isolate road vibration but also allow some axle rotation. Hope that helps a little. See you at Moroso after I get the upper arm replaced.
