Whiteline LCA's...Synthetic elastomer bushings? What are they?

I'm going to be buying LCA's and relocation brackets. Was looking at BMR's, which have polyurethane bushings. http://www.stage3motorsports.com/200...-Bushings.html

Whiteline's have "synthetic elastomer bushings". http://www.americanmuscle.com/whitel...rce=igodigital

What are they, and how do they differ? I want to minimise any increase in NVH. Anyone have any experience with Whiteline?

Synthetic elastomer means good old fashioned artificial rubber, bonded to metal with heat, like a harmonic balancer or torque-tube driveshaft. Obviously, it'll still be stiffer than stock but, noise transference will be less than Poly, Delrin or Heim styles of connection.

The next step up in stiffness, the classic poly bushing tends to not be too great over time. They can end up cracking and needing replacement in situations that place a lot of varied loads on them.

The BMR's look like a nice unit, but my whitelines are very nice too. I don't think you can go wrong with either one.

Also the Whiteline are adjustable.

I went with BMR LCA's and relocation brackets. Hope this fixes my rear end traction issue. I will report.

Good choice!

I assure you, that package will greatly enhance traction.

If you have any questions, you know where I am at.

Thanks for supporting BMR

Glad you have already made your purchase and are on your way to taking your 5.0 faster in and out of the corners.

to answer the original question we originally designed a bushing compound to replace the brass bushings on hill climb vehicles. Over the years our business became centered more around general replacement thus our compound needed to change to minimize NVH associated with Polyurethane. In fact we also make many automotive and non-automotive polyurethane goods - our Polyurethane plant is one of the largest in the world. Our principal formulation has evolved to what we now refer to as Synthetic Elastomer. It is a long chained polymer very similar to Poly but evolved to hold more desired characteristics such as higher tensile strength, elasticity, and memory. It is for these reasons we have engineered features to minimize NVH such as scalloped designs, voiding, pin-holing and of course pocket knurling to maximize grease retention.

In general we look at how an arm moves, how it articulates under various loads, the reason for the articulation and how it effects other components in the Suspension chain - then we design the bushings to allow or restrict those movements to optimize the suspension travel.

Just think about this..... the Mustang has progressed since the 60's to weigh more, go faster, more torque, more suspension demands and more mileage.... yet wheels have gotten larger since the 60's thus lowering tire wall size... if the car has progressed that much shouldn't you expect your bushings to evolve as well? Its a critical item to link between your tires and your steering inputs.

The same function, if not better than conventional poly bushings but with less NVH...sounds like a WIN WIN to me.

Whiteline is a great company. They actually take the time to post on this forum?!? Super awesome:yelpleased:

That's actually pretty cool. I'm sure BMR also browses these threads, but I've had whiteline products for a few years now (a few more cars) and its nothing but the best in my book. Products AND Customer service also.

I have the WL LCA's and re-lo brackets, as well as PHB and brace, and so far am 100% satisfied. I noticed some rear end NVH at first, but it either went away or I became so accustomed that I can't near it anymore.

Solved my wheel hop under most all conditions. I may go with their sway bars, next.
