We have done LOTS of testing both ways, on the road course and drag strip, and can verify that the bushings are not the "sole" problem in this area. They definitely contribute, no question there, but simply replacing bushings does not eliminate wheel hop like a trailing arm with bushings will. These cars are 3800 lbs. Lateral acceleration and braking places extreme loads on this arm as it is the only link responsible for fore/aft wheel deflection under load. If in doubt, don't take our word for it, just read: Quote:

The data that we have been given, shows deflections of the OE assembly, including both of the OE bushings to somewheres in the 12-15mm of deflection under a load equal to a 3000rpm dump. But that deflection is in the bushings and not the arm. We see the arm has in the thousandths of an inch deflection. Doing the bushings is the fix. I will also tell you you are better of if you are doing the trailing arm bushings, to also do the toe lnk bushings because you will get the same deflections with those as well. All of the toe link and trailing arm bushings are the same bushing size and dimensions.
Just my thoughts. mike dms |

Guys, no disrespect, but the outer bushing in the rear upright on a Camaro is in fact a spherical, not that same bushing as the others inboard, or on the toe link. This is a difference between the G8 and the Camaro rear uprights. To replace a spherical with poly would be a step in the wrong direction in our opinion, due to the drastically different compliance values.

This is supposed to be a technical board. It really sucks that some suspension companies come on this board and spread inaccurate information. |

We have a dealer in Ca. that ordered your trailing arm and it did not come with a knuckle bushing. This unit also made a lot of noise and the fix was to remove the BMR arm, and reinstall the OE trailing arm with Pedders bushings front and rear. We have 4 events like this dealing specifically with BMR trailing arms. Now the owner of this forum assured us that you were notified in private about the PRI problem and he closed the thread out of respect for you. But since you asked, this is what happened and why I make the statements that I have. Now being on your web site, you make NO mention of including a outer knuckle bushing with your kit. It I am mistaken I sincerely apologize. And your picture does not appear to have a red poly bushing in the outer knuckle of the trailing arm in your picture Do you need me to give you the link to the thread about the PRI vehicle? I can give you the contact name for Livornia and the customer if you need to verify what I am saying mike dms Last edited by Info@PeddersUSA.com; 02-12-2010 at 02:22 AM. |

The BMR outer trailing arm bushing is black. However, if you know the difference between polyurethane and rubber, you should be able to tell the difference if you are standing next to it. Especially if the car is flipped on its side. BMR part number BK006 is sold separately. Some customers choose to purchase this bushing. Some customers choose to wait and install it later. However, it has been available for quite some time now. It is listed on our website at the bottom of this page: http://www.bmrfabrication.com/F5.htm Since you offered, I will accept your apology. The bushing that you "CLAIM" makes a squeak is a very BMR common bushing. We use this bushing on many, many other suspension components. There are 1000s, maybe even 10,000 suspension components out there with this bushing. We very rarely get a customer complaint for squeaky bushings. When we do get a complaint, it is usually resolved by greasing the 2 face surfaces of the bushings. BMR has NEVER received a customer complaint for squeaky bushings on the Camaro trailing arms. If you were having problems, why didn't you call us? We could have walked you through it. I feel bad for that Camaro owner that removed the BMR parts and replaced them with the stock parts because the bushing was not greased properly. Please send me a PM with the customer's contact info. BMR would be glad to re-install the trailing arms and grease them properly. It is interesting that you have had 4 "events" dealing with BMR trailing arms and yet we have never received a customer complaint that we couldn't resolve. The BMR red polyurethane bushings used on the trailing arm inner bushing are a 95 durometer bushing. BMR uses this bushing durometer on many of our bushing designs. The higher the number, the stiffer the bushing. DMS: What durometer does Pedders offer in their trailing arm bushings? |
