BMR trailing arms, whats the difference?
between these as far as performance and installation...
BMR Trailing Arms with Spherical Bearings (pair) - 2010 Chevy Camaro and BMR Trailing Arms with Polyurethane Bushings (pair) - 2010 Chevy Camaro http://marylandspeed.com/bmr-trailin...27-p-2980.html http://marylandspeed.com/bmr-trailin...26-p-2655.html |
The spherical bearing has no deflection where the polyurethane bushing (although stiffer than stock) will still have a small amount of deflection. The Sperical bearing will transmit more noise into the chassis than the polyurethane.

I have the Spherical Bearing version. I know that in theory, yes the spherical bearings will transmit more noise, and I was expecting it too. But, I didn't notice any additional noise at all. I have noticed that going over speed bumps or a bumpy road is not quite as "smooth" as stock, but I was expecting that too. I think they're great!!

Hmm, do you recommend the spherical or polyurethane? I doubt I'll ever auto cross and I'd like to go to the track maybe a few times a year. I'm thinking the polyurethane should be fine?

You will be fine with the poly bushes.
With sperical bearings on older cars I only noticed the noise when the bearings got a bit worn (they were cheapos). Once I replaced them with a quality rod end it was great. |

I just ordered the bmr trailing arms from apex and now after reading this thread think that I should also get the bushings for them too. Do they really make much of a difference?

I have both the BMR trac arm and toe rods with the poly bushings and they are not that bad as far as noise goes but the difference in handling and traction at the starting line is very noticable over the stock units.
