Is Spherical bushing legal in street prepared for auto-x?

 

I have an older rule book ('05) but I would say no.
As per 15.8 C. : "...If the stock bushings accommodated multi-axis motion via compliance of the component material(s), the replacement bushing may not be changed to accommodate such motion via change in bushing type, for example to a spherical bearing or similar component involving internal moving parts".

Someone better with suspension on fbs could help you out more though.

 

A spherical bushing where? Swaybar end link? LCA mounting point? We need more information to give you a correct answer.

 

Lower control arm and the stay rod/tension rod.

 

Nope, sorry. Not legal in SP.
