Last fall I installed a set of BMR lower control arms with the red poly bushings. I plan to swap out the uppers from the stock to the matching BMR uppers with the same poly bushings and I also planned to install poly axle bushings as well. The more I read about binding issues I’m thinking of just replacing the axle bushing with rubber, so I’m wondering if it’s a good set up to still use the BMR uppers with poly bushing or will there still be binding? Car is a mild street car.

It won't be a problem.

You might consider getting some new OE style upper control arms from LMR or Maximum Motorsports.

The OE type flex and help to mitigate the binding issues.

You could just get a panhard bar and torque arm and get rid of those pesky uppers too

I just installed UPRs upper and lowers and replaced my axle bushings with new poly bushings. Car feels great. Idk about the binding hopefully I won’t in counter that issue. What would one notice if it does bind.

MM recommends keeping rubber bushings in uppers with or without panhard bar. http://www.maximummotorsports.com/tech_rear_susp_panhard.aspx

My combo is Max motorsport lowers with poly bushings.

Uppers are boxed Ford upper control arms with rubber bushings, and rubber bushings in the axle.

The F cam comment was a joke
If your not race'n just use stock uppers, spend your money on things that count like sub frame connectors, better brakes, gears, stuff like that.

I figured. Brakes are on my list. Car already has subframe connectors and gears and some other stuff. My focus now is replacing and upgrading the remaining original parts.

I’m probably just going to be replacing the rubber bushings in the UCAs for now. Thanks for the input everyone.

Same here. I think it's the best of both worlds.

Are the boxed uppers you guys use a different design than the stock ones?

The increased binding from poly bushings in uca would increase the effect of snap oversteer
