Spherical UCR Bushings on the Street?

[comporange04GT]

I have a Maximum Motorsports panhard bar on my car and am getting a little bit of binding in the read suspension. I know that I could install a torque arm and remove the upper control arms but I am not totally sold on the torque arm yet. I know that I can replace the stock bushings on the rear end with spherical bushings but I am wondering if I can install new upper control arms with spherical bushings on the body side too. I know that Steeda sells a set with spherical bushings but they are for track only. Is anyone running a set up like this on the street?

MM does not recommend that. It's either (a) the stock UCA's or (b) the FRPP heavy duty UCA's.

Actually, the stock rubber works well to prevent binding, but only to a certain point in terms of power output. Rubber doesn't bind because, frankly, it's mushy. We've had numerous customers in high (500+) horsepower "heavy weight" cars that have blown away both rubber and urethane bushings.

In the early 2000's we experimented quite a bit (using a handful of employee driven daily-drivers) and put thousands of miles on cars that saw the rigors of South Florida traffic on a daily basis with little to no durability issue. Just for piece of mind, our all of our arms carry a lifetime warranty and are easily serviced.

For bind-free articulation a spherical/heim-joint is the best way to go, and more street friendly than you'd think. If you have any other questions, I'd be glad to answer emails or phone calls.

I've been running Megabite SR lower control arms with heim joints for about a year, daily driven on the street, and have had no problems whatsoever. I'm thinking about doing the same with the upper control arms, I was expecting a lot of vibration and harshness, but honestly, it's barely even louder than stock, the Flowmaster 1 chambers make a lot more vibration and harshness than the heim joints every could......lol
