Has anyone calculated their effective front motion ratio and wheel rates? I'm still getting more body roll than I want even with the bars on full stiff. It seems I need to increase spring rates so I thought I would calculate the effective motion ratio and wheel rate of my current front set up. Keep in mind I've pushed the wheels out pretty far in the front to fit 245 Hoosiers. Just curious what others have calculated.

Wheel: 17x9

Effective Wheel Offset: 11mm

Spring rate (C): 650lbs/in

Sprung Corner Weight: 615lbs

Motion ratio (MR): 0.71

Angle Correction Factor (ACF): 0.98 (for 10 degs)

Wheel Rate (WR) = (MR)^2(C)(ACF) = 324lbs/in

My wheel rate is 50% of my spring rate and 53% of my sprung corner weight, which is pretty soft. The motion ratio is definitely lower than I thought. I'm going to increase the WR 25%, which will require a 800 lbs/in spring.

What do you think? Does the math make sense
