Ref: GCSpanner

This is a replacement spanner for Ground Control coilover kits.

This spanner is included only in certain GC coilover kits, so if your GC coilover kit included a spanner, then you do not need to buy this.

The most common misconception why people think they may need a spanner, is that they are tilting the car on its side to adjust the collars, so they are fighting the swaybars. The swaybars are designed to keep the car from tilting by pushing against the suspension, which makes it difficult to turn the adjuster by hand.

A spanner could easily ruin things if used under these conditions.

If this describes your situation, try lifting the front or rear of the car off the ground, and adjust with your hands.

Powerflex uprated suspension bushes, available in 'STREET' for normal road use or 'BLACK' for track/racing use.

Polyurethane has been with us as a specialised plastic for some thirty years. However recent advances have now made it possible to engineer very special properties into this exciting material. Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.

The material that OEM bushes are manufactured from, is a rubber compound containing natural products which deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.

This in turn causes accelerated tyre wear, braking instability and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car compared to a showroom new one. However even new cars will benefit from POWERFLEX bushes because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.

POWERFLEX for prolonged tyre life. With the technological advances in the material used, it has been possible to overcome the common problem associated with harder bushes, which is increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.

POWERFLEX bushes make sense.
POWERFLEX for improved performance.
POWERFLEX for increased safety.

Get in Control!

Are you looking for more control over the front end of your BMW? 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 centre 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 product fits the following vehicles:
- F8X M2, M3, M4, E9x M3

*(Priced per pair)*

Please specify your vehicle model when ordering.
Please specify if you want STREET (black) or RACE (blue) use bushes when ordering

Made from best quality PU materials, these engine mounts are available for all 6 cylinder E36/46 /Z3 / Z4 and related M models.

25% stiffer than factory mounts, suitable for road and track use, without the harshness of full race mounts .

Specially shaped for best performance and installation ease.

Benefits:

- More torque to the rear wheels (a portion of an engine's torque is used in lifting it's own weight against the mounts, so the stiffer the mount the less lifting and the more torque to the wheels)
- Smoother gearshifts with less missed gears.
- Less engine movement under hard acceleration / braking

We also offer a Yellow edition engine mount, please refer to Variations section ( use the red link button at top right of this listing ) for details on this version.
