Quick discussion on swaybars. Seems both front and rear OE SS 1LE bars are bonded bushing type. This means they do not rotate within their bushings and can actually contribute some spring rate to the chassis through the swaybar mounts. This effect is nothing at factory ride height, but it increases in both ways with suspension movement. When replacing these bushings with greased poly, you are actually reducing the effective spring rate at the wheels. I am curious how much the effect is, but I'm sure it is significant given the stock springs are not that stiff.



It is a curious thing that might be legal to adopt a bonded bushing type that can make the bushing spring rate even more stiff. Part B of the rules sort of covers that, but maybe not clearly:

13.7 ANTI-ROLL (SWAY) BARS
A. Substitution, addition, or removal of a single anti-roll bar and supporting hardware (brackets, endlinks, bushings, etc.) is permitted. The use of any bushing material is permitted. A bushing may be implemented as a bearing.
B. Substitution, addition, or removal of anti-roll bars may serve no other purpose than that of an anti-roll bar.
C. No modification to the body, frame, or other components to accommodate anti-roll bar addition or substitution is allowed except for the drilling of holes for mounting bolts. Non-standard lateral members which connect between the brackets for the bar are not permitted.


Until I get a chance to measure the effect, I'll be sticking to the stock bars :P
