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?

The polyurethane version will be just fine. Just be sure to also get the outer trailing arm bushings. They come separately. Feel free to hit me up if you have any questions. |

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. |

This is 100% correct. Most guys that install the trailing arms with the spherical bearings don't really notice a difference in road noise or vibrations, we just like to warn people that it me because they are solid mounted and some people are more sensitive to that kind of stuff than others.

Everybody has different tolerances of what they can take so we make sure we give people options that will fit there needs. I am more than happy to talk to anyone who has questions on the differences between them.

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?

The outer trailing arm bushings definitely make a pretty noticeable difference and I would really recommend that the bushings be installed at the same time as the trailing arms since there is some overlapping labor. They are inexpensive and relatively easy to install and a good thing for any 2010+ Camaro owner to have.

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.

I think they are some of the best bang for the buck parts we sell for the late model Camaro. They are reasonably priced and not hard to install but make a considerable difference not only in straight line traction and performance but in handling situation also. Probably 80% of the trailing arms and toe rods we sell are the poly-urethane version because people want the performance they can get without sacrificing any of the great driveability of the car.
