*PAGE CURRENTLY UNDER CONSTRUCTION*

AKG Motorsport manufactures the highest-quality bushings, mounts, shifters and performance parts available for BMW. They are experts in BMW who pioneered aftermarket performance bushings, mounts, shifters and more all the way back to the 2002 and E30. All of their race-proven parts are original designs – not the other guys!

AKG parts are unequaled in their design & manufacturing, and crafted out of the highest-quality materials available – such as 6061 & 7075 T6 aluminum and exclusive U.S. Military Spec polyurethane. In addition, they are the only aftermarket BMW parts manufacturer that molds polyurethane in the USA under strict ISO 9001:2015 certified standards – and that’s a BIG deal. AKG performance parts for BMW are available in the UK through Crest Automotive.

Bushings

AKG Motorsports solid aluminum BMW bushings are the hardest available and have a longer life span than other bushings. Strictly for race purposes and made of solid CNC’d 6061- T6 aluminum.

Chassis Reinforcements

AKG Motorsports race-proven reinforcement kits are the thickest on the market and are engineered to properly reinforce failure-prone mounting points. Unlike others, these reinforcement kits strengthen the area correctly, utilizing extra-thick steel which is designed to precisely cover only the surface area that is vulnerable.
Precision CNC laser cut and bent.

Suspension Components

Supplying a variety of suspension parts from adjustable control arms to sway bar links, AKG Motorsport specialise in these areas using high quality and lightweight CNC’d aluminum with teflon lined components. Their control arm bushings are made from exclusive U.S. Military Spec polyurethane (85A hardness).

Motor and Trans Mounts

AKG Motorsports BMW Aluminum Motor and Trans Mounts work together to eliminate all engine and transmission movement for effective power transfer through the drivetrain. Designed for racing, their bolt-through solid aluminum mounts are engineered to be both strong and lightweight. Eliminate drivetrain movement with an aluminum motor and trans mount set.

Steering

The AKG Motorsport Aluminum Steering Flex Shaft Coupling eliminates the factory rubber steering shaft coupling for precise steering input and completely solid feedback. The factory rubber flex shaft coupling is fine for a street car, but it doesn’t give proper steering feedback for a race car. These kits replace the stock rubber coupling for most precise steering feedback possible. Made of solid CNC’d 6061- T6 aluminum. Engineered for a perfect fit.

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

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.
