The closer those ovals are to the rear of the car, the more "erratic" the axle is.....and the more important it is to ensure you have proper rear shock adjustment.

The further the oval, the less the "hit" will be....axle will be more stable. The long Instant Center will provide a much less erratic axle...as the "hit"s isn't drastic....however, the load to the tires will be more consistent/constant..

You guys in the 28.5"+ height range, will likely have your best "overall" luck with the UCA in the upper-most position....and the LCA in the middle of the BMR tells

that's how I'm configured for tonight!

thanks guys that helps! I edited the drawing so this is exactly how I am setup right now (blue line)
This seems pretty mild to me, so I should be in good shape. does launch very nice now... but if I can get more out of it I will keep testing different places.

Looks like moving the UCA angle affects the A/S alot more than moving the LCA down a notch.

It depends.

Typcially, moving the LCA down, will "raise" the AS% slightly more - which will "hit" the tires harder.

When in doubt, run a little more aggressive Anti-Squat and sidestep the clutch off the limiter. That's what Chad does! (GT.350R)

the red line got me a best of 12.425 w/1.67 60' and I'm at the green recommended setup for the testing tonight - can't wait to see the results!

This should help out a little more. I have added an imaginary line. The further above the line, your point...the higher the AS%. On the line, 100% AS (no raise, no squat) and the further below the line, the more squat.

It is not super precise, but I made an educated guess.

Again, that line is not 100% accurate.

BUT, it will help you get an idea of where you are at.
