Michael, why not spherical bushing on both sides of that upper arm then? Does nobody make the parts or are you running urethane on one side on purpose? What are you running on the lower arms?

You can not buy just a spherical bushing for the body side of the arm. The only way to get a spherical bushing in the body side is to get an aftermarket UCA and I think all of them are adjustable. (Not 100% sure though) Like the link below:

On the lower I am running the MM "Heavy duty" arms. They have spherical on the diff end and poly on the body end. MM does make an "Extreme Duty" arm that does have spherical on both ends.

Everyone wanted more hp, bigger brakes and more traction (CMC2).. ALL these things add stress to a stock chassis.
I believe someone mentioned AI lite... well thats where its going...
there was NOTHING wrong with CMC1... BUT NOOOOOO...
Instead of practice and improving driving skills, we work on making the car faster instead of making the driver faster...
I would love to switch cars sometime and compare lap times... Owner drives contingency races and switch for the other two..
Just sayin....
If a rule change would be made to allow aftermarket upper arms, you could put together a spherical bearing upper arm for about $75 from the Coleman Catalog...

If such a rule were written, is your intent to replace only the right side upper control arm with a custom arm with spherical bearings, or would you come up with something that connected a fabbed single upper arm down the centerline to some type of bracketry that tied the two body and the two axle attachment points together for potential added strength?
