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.

For race use only.

If you want to prevent torque loss and are tired of the missed shifts and other issues related to soggy, failure-prone mounts, then our solid mounts are the solution.

Solid Engine & Transmission Mounts eliminate all flexing and mount failures that can occur due to movement in your drivetrain. Many failures happen because Mounts are not "bolt though type". Our mounts are basically indestructible and have been used on 4-digit horsepower cars for the ultimate in torture test proven reliability.

Solid mounts also give increased rear wheel torque (a portion of the engine's torque output is used in lifting the engine / gearbox against the OE type rubber mounts)

All mounts are beautifully machined from 6061 T6 billet aluminum in the USA.

RE part number TM

What is a transmission mount?

The transmission mounts in a BMW are a common part that is frequently overlooked.

The transmission mount is designed to do the following:

Help stabilize the transmission under vehicle load allowing the shifter to engage into gear properly.
Isolate vibration from the drivetrain to the chassis.

Under engine load, the transmission can wiggle left and right slightly, worse when the car is being driven hard into turns. This unwanted movement may potentially causing the driver to miss shift. When we sought to have our own transmission mounts produced, we wanted them to be compliant for street use, with no compromises in performance.

What we have is a transmission mount made from Neoprene rubber, with a completely different shape than the factory mount. The hourglass shape of the factory mount is not the best for stabilizing the transmission. By changing the shape to the cylindrical shape of the Rogue Engineering mount, it reduces deflection significantly, while maintaining damping.

The Rogue Transmission Mounts are sold as a pair, and come with Grade 8 Zinc plated hardware. Unlike other aftermarket mounts, the mounting plate and studs of our mounts have been Cadmium plated to prevent corrosion.

Note: Priced as a pair.
