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.

The World's Best Selling and Best Performing Rear Shock Mount for z3/4/E36/46 Models !

The BMW factory rear shock top mounts are well documented as a very poor design, even when brand new they perform VERY poorly, far too much movement in them, and they are essentially worn out every 20- 30 k miles.

Say goodbye to vague real chessis feel rear end clunks! With the introduction of the Rogue Engineering Rear Shock Mounts, you have a high quality, rebuildable, easily serviceable rear shock mount.

Fits the following vehicles...
All E30, including M3
All E36, including M3, Z3 and 318ti
All E46, including M3
All Z4, including MZ4

Rogue Engineering Rear Shock Mount Set includes:

Two (2) Rogue Engineering 6061-T6 CNC, Anodized Rear Shock Mounts.
Four (4) Shore A 65 Bushings (2 required per mount).
Two (2) 303 Stainless Steel Bushing Spacers (to be used with standard 10mm rear shocks).
Four (4) 303 Stainless Steel Washers (2 required per mount).
Four (4) Yellow Zinc plated serrated lock nuts.
Two (2) Shock Tower Reinforcement Assemblies (with 10.9 hardware welded).
Two (2) factory gaskets (#3352 1128 734).

Problems with Factory Mounts
The factory BMW rear shock mounts are generally a little soft, to provide the most possible acoustically dampening in the vehicle. However, design precludes them from being stout enough to withstand the rigours of aftermarket suspension, or even badly damaged roads. A decent sized pothole can send a perfectly good factory rear shock mount to pop out, making it entirely useless necessitating replacement. Upgrading to E46 M3 rear mounts (a popular alternative) is not a guarantee that it doesn't happen again and again.

Rogue Engineering Rear Shock Mount Features
By producing a rear shock machined from 6061-T6 aluminum, we are able to attain a more stable and stiffer platform which to mount the top of the rear shock. However, rather than use race-only spherical bearings or even overly stiff urethane bushings, we specify Shore A 60 hardness rubber bushings (approximately 30% stiffer than the factory bushings) to allow for street comfort and compliance. Our findings show that overly stiff urethane bushings do not allow the rear shock to move, making the attachment of the lower part of the shock under strain.

The construction of the aluminum shock mount plate and orientation of the bushings makes it impossible for the bushings to "pop out" in the manner which the factory style mounts fail. Since the bushings are rubber, when they require replacement, rebuilding them takes only a matter of minutes. Only 4 bushings require replacement (for a pair of RSMs) and are available at extra cost.

Other important details include the use of 303 stainless steel components (compression washers and spacers) for long-lasting corrosion resistance. All other hardware is metric, and either Grade 8 or better, treated with a yellow zinc plating, again for corrosion resistance.

Another feature is the reinforcement assembly which secures the rear shock mount to the vehicle. By reinforcing the top of the shock tower in the vehicle, it protect against the rear shock from ripping out the sheet metal. The reinforcement has its hardware welded to it, allowing for the rear shock mount to become a bottom-mount design. This means that if the rear shocks need to be removed, it only requires removing the two nuts and the single bolt at the bottom of the shock. No need to completely disassemble the trunk area to gain access. If being used with a rear strut tower brace, the reinforcement assembly may be mounted from the bottom, so that the rear shock mount can be secured in the traditional manner.

The Rogue Engineering Rear Shock Mounts are designed to be used with standard 10mm rear shocks, but can also be used with 12mm adjustable race shocks with the use of optional washers.

Rogue Engineering Rear Shock Mounts ~ MONOBALL

RE part number re.rsm.mono

Rogue Engineering famous Rear Shock Mounts are now available in Monoball version! These have the same features of their RSMs, but instead of rubber bushings, a high quality spherical bearing. This eliminates the movement and "slop" of the rubber.

Not just for "racers", these are for people that want only the best quality parts on their BMW. Not all spherical bearings mean harsh rides in the cabin A stiff spring rate has more to do with the ride quality than a spherical bearing mount such as these. Actually, if you run a front camber plate, you already run a spherical bearing component on your vehicle.

Rogue Engineering Monoball Rear Shock Mount Set includes:
- Two (2) Rogue Engineering 6061-T6 CNC, Anodized Rear Shock Mounts assembled with US-made spherical bearings.
- Four (4) Yellow Zinc plated M8 serrated lock nuts
- Two (2) Shock Tower Reinforcement Assemblies (with 10.9 hardware welded)
- Two (2) factory gaskets
- Two (2) Black short bearing spacers for 10mm shocks (top of RSM)
- Two (2) Black tall bearing spacers for 10mm shocks (bottom of RSM)
- Two (2) Blue short bearing spacers for 12mm shocks (top of RSM)
- Two (2) Blue tall bearing spacers for 12mm shocks (bottom of RSM)
- Protection and Quick Installation/Removal

Another unique feature is the reinforcement assembly which secures the rear shock mount to the vehicle. By reinforcing the top of the shock tower in the vehicle, it protect against the rear shock from ripping out the sheet metal.

The Rogue Engineering MONOBALL Rear Shock Mounts are designed to be used with standard 10mm shaft diameter rear shocks or 12mm shaft diameter shocks (shocks typically with top adjustments) with the included hardware. Additionally, the reinforcement has its hardware welded to it, allowing for the rear shock mount to become a bottom-mount design. This means that if the rear shocks need to be removed, it only requires removing the two nuts and the single bolt at the bottom of the shock. Once installed, there is no need to completely disassemble the trunk area to gain access. If being used with a rear strut tower brace, the reinforcement assembly may be mounted from the bottom, so that the rear shock mount can be secured in the traditional manner.

** THIS PAGE LISTS THE BUSHES FOR THE E46 CHASSIS INC M3. PLEASE SEE VARIATIONS SECTION ( USE RED LINK BUTTON AT TOP RIGHT OF THIS LISTING) TO ACESS E30 AND E36 VERSIONS.

After much Reserch and development and testing, Rogue Engineering is proud to introduce its Performance Front Control Arm Bushings (FCAB). A unique combination of CNC'd 6061-T6 aluminum and high performance urethane, we can now offer a bushing that is performance oriented enough for the track junkie yet without significant increases in Noise Vibration and Hardness when used on the street.

Factory bushings are more than adequate for street driving. However, when the miles start to pile up, the bushings are meant to be replaced. Common side effects of worn factory FCABs include, but are not limited to the following:

- Steering wheel shutter when brakes are applied
- Wheel (and steering wheel) shimmy
- Mysterious and irregular tyre wear
- "Overboosted" steering feel (very light steering)

Replacing factory bushings, with new factory bushings will return the factory feel.
However, we offer something that gives you MORE.

RE Performance FCABs
With the numerous delrin/urethane/hybrid replacement bushings in the market, we vowed to make something that was not only effective, but simple.

- No clips,
- no washers,
- no multiple sleeves,
- no "race parts in street cars".

Some of the feature benefits of our Performance FCABs include:

- Servicable/rebuildable (replacement of bushing insert)
- Urethane insert prevents unwanted control arm deflection while allowing NVH isolation
- Eliminates steering shimmy and wander, especially with the addition of big brake upgrades
- Unchanged steering geometry
- Direct "connected" feeing with front end of vehicle
- Easy to install (professional installation recommended)

During our testing, we found that our Performance FCABs deflected much less than new OEM bushings. (see attached graph).

In our development, we were able to limit the amount of bushing deflection while also controlling the amount of Noise Vibration and Hardness being transmitted through the bushing itself by the durometer of the urethane insert. We discovered that increasing the durometer stiffness (to nearly the harness of plastic or delrin), we were able to limit the movement of the bushing so that it didn't move at all. However, we got too much Noise Vibration and Hardmess to be used in a street driven car. When we reduced the durometer too much, we had a very comfortable bushing, with stock-like performance. Of course, with our goals, we were looking for performance one could live with everyday.

Installation Notes

Access to the underside of the vehicle is required and professional installation is recommended.

The RE Performance FCABs reuse the factory "lollipops", as the aluminum sleeve of the FCAB is pressed into place (hydraulic press is required for removal of stock bushing and installation of RE FCABs).

Available in both 60mm and 66mm. Please specify which size required.

**NOTE: these bushes are designed to be installed with the ROGUE housings (60 or 66mm depending on vehicle), these are INCLUDED in the price. Please specify EXACT model and year of your vehicle when ordering.

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.

A popular and inexpensive upgrade for the transmission mount is the installation of the BMW 320i tranny mount.

Originally used on the older E21 3-series, it's cylindrical shape deflects less than the mounts found on recent BMWs. Installing the 320i mounts requires very little modification, and it yields significantly less deflection without any additional vibration or otherwise uncomfortable side effect.

Testing of the stock E36 M3 tranny mount and the 320i mount showed that the 320i mount deflected 24% less than the E36 M3 version (a good thing). In the effort to find a solution that would yield even greater results, UUC Motorwerks began research the various options.

There are replacement aftermarket tranny mount systems which do a notable job of addressing transmission movement, but at the expense of excessive interior cabin vibration. Additionally, such system can cost upwards of a few hundred dollars. Like all UUC Motorwerks products, our goal is to create products which can be used in a daily driver while maintaining the benefits for performance driving. Such is the case with the Tranny Mount Enforcer.

The Tranny Mount Enforcer is an add-on piece to the 320i mount which inhibits a noticeable degree of deflection. The Tranny Mount Enforcer is CNC'd from 6061-T6 aluminum. For best results, we recommend using the specially-designed UUC Transmission Mount Bushings which do not require the slight modification to the transmission cross brace that the 320i bushings do.
