In order to mount aftermarket seats in your car, you need a floor mount adapter. These high-quality aluminum adapters are made by Macht Schnell. These bolt to your existing seat mounting studs in the floor and offer the lowest profile of any floor mount (22mm height). This helps to keep your seat at the lowest position possible. Your seat adapters or sliders bolt to this adapter plate. These floor mounts are a matrix style with rows of threaded holes that allow you to find an ideal seat location. There are other options - including homemade - but these seat brackets for your BMW are the highest quality to match your expensive seats.

Sold per seat. Can be used on left or right sides of vehicle.

These adapters were originally designed for the E46 chassis. They can fit the E36 by modifying the mounting holes to match the bolt and stud locations on the E36 floor.

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

Stock Flywheel Weight = 25.0lbs
JB Flywheel Weight = 10.0lbs

When you push your powerplant, thermodynamics push right back. The toll of high performance is higher heat load – and many stock components begin to complain. But Active Autowerke has you covered - this upgraded fan clutch increases viscous coupling of cooling fan blade speed to water pump speed, yielding increased airflow through the radiator for more efficient cooling. A simple, yet wonderful, thing.

The ultimate in a racing flywheel and clutch! This was developed for use in our E36 and E46 World Challenge Touring Cars. The combined weight of the clutch and flywheel is only 11lbs!!!

This multi-disc (2 or 3 disc setups) offer a minimal flywheel mass (enough to include a factory ring gear for the starter) and a small 5.5" clutch assembly rated to 500ft-lbs. By saving as much weight as possible less energy is used in simply spinning the flywheel/clutch assembly and that means a lot more power and torque is available at the drive wheels. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines and this is among the most advanced and lightest racing clutch kits available for your BMW race car.

The JB Ultra-Light Performance racing clutch is available in 2-disc or 3-disc setups. A 3-disc setup is less susceptible to heat and will have a higher torque capacity. On our M54-powered 325i Touring Cars (approximately 300hp) we used the 5.5"/140mm 2-disc configuration. The 5.5" clutch was a perfect blend of performance and durability. It wasn't too small to suffer from high temperatures and wasn't too large that it couldn't be slipped (slipping prevents damage to other components). This is a turn-key racing clutch and flywheel kit that you don't have to engineer or spec yourself. This is the same clutch setup we used when winning the 2003 and 2004 Touring Car Championships - the quality and performance is unquestionable. That series also employed standing starts at each race and this clutch setup performed flawlessly with nearly a full season of racing on them before needing a change.

JB Ultra-Light flywheels include:
  • precision CNC machined aluminum flywheel
  • zero-balanced
  • replaceable hardened steel clutch friction surface
  • Helicoil threaded inserts
  • high-strength grade 10.9 hardware
  • multi-disc Sachs or Powertrain Technology racing clutch with racing pressure plate
  • JB Racing throw-out bearing with custom bobbin
    This is a true racing clutch and will not function as a street-able clutch at all. It behaves as an on/off switch with no slippage allowed. Extreme care must be used when driving on to trailers and around the paddock. But when driven correctly the life span of this clutch is amazing - we could get a full season of racing a 300hp M54 from this clutch setup including standing starts at every race! Replacement clutch components and flywheel rebuilding are available.

    A properly adjusted clutch stop is required for use with this clutch kit.

    Stock Flywheel + Clutch Weight = 45+lbs
    JB Ultra-Light Flywheel & Clutch Weight = 11lbs

    As the producer of one of the finest working supercharger systems for the BMW E46 M3, Active Autowerke is proud to introduce the PRIMA PLUS supercharger system capable of exceeding 500 WHP running on pump drawn 93 octane. The PRIMA PLUS is an upgrade kit to the existing PRIMA supercharger system designed to create MORE horsepower. In collaboration with Frank Smith of Tuning Tech FS, the Prima PLUS SC kit has evolved as a fantastic performer. With numerous dyno runs under countless hours all monitored through careful Data Logging and Lean/Rich evaluation, this PRIMA PLUS supercharger kit is ready for the BMW enthusiast. The PRIMA PLUS is a centrifugal design supercharger using a conventional fixed drive pulley, but unlike its predecessors, the PRIMA PLUS also has variable boost settings of 9.0 psi and 9.5 psi to help attain the power. A first in the BMW forced induction industry. For easy comparisons, here is where the PRIMA and PRIMA PLUS + stands when measuring rear wheel horsepower. A stock BMW E46 M3 is around 265 WHP. | PRIMA SC makes 425 WHP. | PRIMA PLUS SC makes 500+ WHP.

    Race on Sunday, to sell on Monday. This old saying is indicative of the new Generation 8 supercharger system for the E46 M3. Through countless hours of testing, it has often been quoted that the true test has always been a race environment. What better venue than Brock Yates One Lap of America Race. With a rigorous 7,000 miles to be covered within a week, and to compete against the likes of Porsches, Corvettes, Nissan GTRs, this would be the testing grounds for the new Generation Active Autowerke Supercharger system. The Active Autowerke Generation 8 Supercharger System not only proved its worth by being the highest ranked BMW within the field, but also ranked 1st in its class..

    The data and technology that made this winning combination is now being applied in the new Generation 8 of the Active Autowerke supercharged E46 M3 level 1. Reliability and power is needed if you want to be on the podium, and this new Generation 8 will deliver exactly that. Consistent, repeatable runs of over 415 WHP (525 engine horsepower) were also recorded on the Active Autowerke chassis dyno in hot 94 + degree Fahrenheit conditions with humidity in the 60% + range. These run conditions might be considered a deterrent and not really suited, but it is better knowing the horsepower numbers are under such conditions, since higher horsepower numbers will only increase as the temperature falls and the air becomes more dense.

    Stage 1 Performance Specs:
    Power : 525 BHP @ 7650 rpm
    Torque : 335 ft/lbs @ 5400 rpm
    Boost Level : 7-8 psi

    Key Features:
  • Rotrex 92 Trim Supercharger
  • Active Autowerke Gen 7 Intake Manifold w/ Dual By Pass Valve
  • Front Mount Air to Air Intercooler

    Turbo vehicles often suffer from heat soak - methanol injection systems help cool the intake charge, and increases your engine’s knock limit – giving you a failsafe against high boost detonation. Active Autowerke's methanol-water is precisely delivered and metered by its own electronic module, which measures boost pressure within the engine and controls the delivery flow to match both the engine load and demand as needed.

    • The large 1.8+ gallon reservoir
    • Rigid mount can be easily detached if needed by its spring loaded quick releases.

    Many racing series and event organizers are requiring 5 or 6-point harnesses in their events now. Attaching the anchor points to the seat base is a desired alternative to drilling holes in your floor and carpet*. This set includes the 6-point anchor to attach to the Macht Schnell floor mount as well as side attachments for either a bolt-in or snap-in harness.

    * - note that most racing harness manufacturers will advise that drilling through the floor is the best method for mounting harnesses. This allows you to locate the mount in the ideal location and angle to fit your driving position. The proper installation is paramount to ensure the harness works correctly in an impact.

    Sold per seat.

    This lightened steel flywheel is specifically designed (and approved) for use in Grand-Am road racing but can also be used as a mild street upgrade if a full aluminum lightweight flywheel is not called for. The Grand-Am flywheel is 20% lighter than stock to meet the rules for the GS and ST classes.Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

    In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. The engine revs much faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

    Grand-Am approved this flywheel to be used with a factory E36 M3 clutch. This opens up a lot of clutch and pressure plate options but we typically used this with a stock Sachs OEM clutch kit. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches.

    Lightweight flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

    If being used on a 330i 6-speed or Z4 6-speed an additional pilot bearing hub is required. Select your appropriate model and transmission from the list below.

    Stock Flywheel Weight = 25.0lbs
    JB Flywheel Weight = 20.0lbs
