Is anyone running the Mazdspeed motorsports spherical bearings for the front control arms and rear trailing links on the street on an FB? Are they even streetable? I'm not sure if they are legal in my class but I'm looking at them as an option.

The only problem with spherical bearings is the wear. They are not a part that will go for 10s of thousands of miles on a street car. It's a item that gets replaced atleast once a year on a track car. If you don't mind the expense and labor have at it.

That's what I thought. Since my FB is going to be mainly an AutoX car but also street driven quite often, I'll have to think about it. Thanks for the help.

Realistically....

Poly is for the street..

Delrin is for Race.. As it will wear out like a brass bushing over a period of time.

Spherical bearings.. Auroras.. Rod ends.. whatever you like..
Race ONLY.
They click, clink, pink, rattle etc etc etc..
They have VERY close tolerances.. but after adding a handful of them.. the very small tolerances add up.
Then as they wear over time.. the clearances increase with time quickly on the street.
You also will be putting them through a ton more abuse than on the track.
They also will not hold up to too many train tracks..
