Stillen Sway Bar Charts

Trilitheum

Thought I would put these up for anyone else who is interested. I recently purchased the Stillen sway bar kit and was trying to understand how much adjustability was possible between the two bars.

The charts show all the possibilities between the two bars and the relative changes from OEM that can be set with the bars.

What I was trying to determine was how much the balance of the car could be changed. Obviously the higher the % stiffer than stock the less roll, but I was more interested in how it would change the over/understeer tendency, which depends more on the ratio of front to back, not the absolute values.

Due to a host of variables, the percentages and numbers won't directly translate in X percentage increase in over or understeer on the car but it gives an idea.

Stock OEM ratio of front/rear is ~1.04 (Green), so for example anyone interested in keeping the same car balance on these bars but want less roll the settings would be 4 in the front and 1 in the rear.

From reading other threads it appears that with the stock suspension, a close to neutral balance is around a setting of 3 on the front and 2 on the back (ratio of 0.87), so this can be used as reference point for adjusting either way on a otherwise stock car. If you modified your suspension, tire size, spacers, etc. these guidelines don't apply!
