Have you ever considered "de-powering" your rack?
Yes, I have considered it, but have chosen not to. I'm more attracted to a stock steering rack, than the potential weight savings by modifying it. I don't enter my car into any competitions, so saving weight isn't too big of a deal for me. Maybe some day, if I get bored....

Here you go Max; give these a shot.
Each graph represent the suspension being moved from 2" of bump to 2" of droop. For each graph, the chassis is at a different roll angle. The first graph represents 0 degrees of chassis roll and the last graph is 2 degrees of chassis roll.
The roll center movement does not look bad in droop but in bump it seems to shoot off into space once you get beyond 1" of bump.
Thanks Andrew for making the graphs for me, I really appreciate it. But, I'm not too sure how to interpret that data? I understand that the kinematic roll-center method has an "error" in it, as Kurt has said, but this leaves me even more confused. I am unaware of the forced-based analysis, and don't really want to take the time to study it at this point. Should I then ignore the left side of the graph, and assume that this suspension has good control over the roll center? With my limited expertise/ understanding, I think that this geometry will be good. Will others agree or disagree?
I have a 9 day break from school starting this Saturday, so if I can get my designs wrapped up this week, I can start to make some A-arms this week, and maybe cut off my rear end next week
(scary thought). I bought some steel today for the A-arms, and may buy some aluminum sheet this Saturday. I can't believe the price of it! It was $150 per sheet for a 4x8 0.040"THK sheet 2 years ago, now its $68! Wow!
