Lonnie,
I found this one that indicates it's a .xls, so see if you can open this one.

I believe those calculations find the equivalent spring rate at the end of the bar. You still have to figure the motion/spring ratio based on swaybar connector rod geometry.

Bobber,
It requires all of the suspension geometry to be input and it does calc the anti-roll bar and spring contribution in inch-pounds per degree of body roll.

Yes, it's a solid 3/4" bar. The finished bar has a gusset reinforcing the bend in the plate steel arm.



Nice fenders; are they custom or purchased?

If the latter, where from?

Noah,
The fenders are from an early 80's Caterham. I don't know if the current Caterham clamshells are the same.
Josh at Rocky Mountain Caterham would know.
