Now that I'm done with track days this year until march next year, I'm looking at some improvements I can make to the car. I researched some for spherical ends on controls arms, and BMR, Whiteline, and Maximum Motorsports came up.

What are you guys running, and how do you like them?

I found that the feeling in the rear (of the car) improved with the spherical bearings we put in both ends of a BMR LCA. On the street you do get some interesting noises but well worth it. The original poly bushing had way to much movement

Thanks man, but yeah the car isn't my daily so not worried about noise. Just heard loads of good things about spherical. Just not sure on what brand to go with.

I’m using the UMI roto joint LCA’s. Huge difference compared to factory and a fraction of the NVH penalty compared to full spherical. It’s basically a spherical joint with a derlin bushing between the ball and the socket. The only downside is that it needs to be taken apart and greased once or twice a season, depending on how much time you spend on track and temperature/heat. I’m not sure if UMI makes a full spherical joint but if they do, I’d recommend them based on the quality of the one I got and the service.
