Rogue Engineering Front Tension Rod/Arm Upgraded Bushing

Get in Control!

Are you looking for more control over the front end of your E9X M3? We've got the solution for you!

While the stock front tension arm bushings are designed to offer a compliant ride while trying to control the front, it cannot overcome age, added power, or increase use (like at the track). This front bushing takes a large share of the suspension load under braking and hard cornering. Our solution is designed to to outlast and outperform the factory bushing in many ways.

Rogue Engineering's Tension Arm Bushings (TABs) is an elegant, engineered solution to this issue.



Rogue Engineering's TABs are designed allow the thrust arm to move without this spring load, but instead, allowing movement though its range without this specific resistance. By allowing the center bolt sleeve to pivot instead of our custom urethane-silicone bushings smoothly, there is no unnecessary wear and tear.

Our exclusive, made in USA, urethane bushing has all the same properties as the other bushings Rogue Engineering produces. A special silicone formula is injected into each and every bushing mold during the casting process to ensure a lubricious film impregnated at all times (even without grease!).

Another Urethane Bushing?

Some will try to compare the Rogue Engineering Thrust Arm Bushings to a currently available urethane replacements. There is a big difference! Instead of using urethane to control the entire area of deflection, we've engineered an aluminum housing to reduce the ID of the hole of the thrust arm bushing. By doing this, we can fine tune the urethane compound so that we can get performance without unwanted NVH. In order to get our level of deflection control, other companies would have to make their entire bushing so incredibly hard that their product would either vibrate, squeak or both!



Less unwanted bushing deflection means more control! Take control of your BMW! These bushings are available in our STREET compound (black) or TRACK compound (blue).

This produce fits the following vehicles:

E9X M3, including Coupe, Sedan and Convertible
E9X 3-series with E9X M3 front tension arm retrofitted
E82 1 M Coupe
E8x 1-series with E9x M3 tension arm retrofitted

$239

And of course Rogue also ignores the fact that OE "M" is vastly different from OE "non-M".

What you are looking at is marketing BS.

Yes, I can believe OE none M bushings deflect 25+mm under load.

A useful comparison would have shown compliance = deflection / load

Implicit in the Rogue graph is that whatever the load, it is the same in each case. For the data to have any meaning, whatever that load is, it must be attainable in service.

Have a look at the construction of an OE front tension arm bushing and explain how it can deflect 25 mm.

The bolt hole is about 12 mm diameter, meaning you believe that the bushing can deflect by two bolt holes under a load that can be seen in service.

You do know that there are deflection limiting bumpers on that bushing don't you? There is not enough space between the inner and outer shells for 25 mm deflection to be possible.

Rogue's graph pretends to be data, but without the load component being specified, the graph itself is a "load". You are too eager to accept marketing hype.
