BMW Drive Belts & V-Belts for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

Please ensure your correct model is selected

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

NOTE: Due to space limitations, the design of this damper will overdrive your components (water pump, power steering, and alternator) by approximately 10-13%; we highly recommend using underdrive pulleys in your setup Controlling the harmonic resonance of the BMW S14 engine is highly important as RPMs rise, but the ideal configuration of the 4-cylinder motor makes even the most experienced engine builders overlook some fundamental principles of engine harmonics that can be destructive. Harmonics destroy these motors by causing extensive oil pump and crankshaft damage, but the addition of VAC’s Harmonic Damper eliminates the unstable crankshaft harmonic vibrations that cause internal engine wear. By eliminating harmonic vibrations, your S14 engine will be able to produce more horsepower and torque with increased reliability. The VAC/ATI Harmonic Damper is made with an integral pulley, eliminating the need for the additional pulley other models require. Exceeds SFI 18.1 Safety Certification Eliminates problems with lightweight clutch and flywheel assemblies Controls destructive harmonic forces Reduces instances of bearing wear, accessory failure and oil pump failure Includes lightweight VAC Billet Crankshaft Pulley Made in USA ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and track applications.

Group A racecars were the top of their class in both touring car and rally racing. Heavily modified and extremely fast these cars set out to demonstrate the best of what a manufacturer could do on the racetrack. It was the predecessor to the current DTM class racing and set a standard for many other divisions of motorsport to follow.  

One of the weaker points of the S14 engine, when speaking from a racing standpoint is the belt drive system. While fine for a street going car, a V-belt is not suitable for high RPM applications. On the track, most of your time will be spent in the higher rev range which puts extreme amounts of stress on the factory setup. BMW realised this and came up with a solution that involved doing away with the V belt system and using a 6 rib serpentine style instead.

Extremely resistant to slippage and failure this design holds up much better the abuse of track duty and won't leave you stranded and waiting for tow back to the pit. Additionally, this kit does not accommodate and a/c compressor and the alternator and waterpump are underdriven by way of slightly larger pulleys. Combined, this puts less of a load on the crankshaft which leads to more efficient power delivery to the ground. If you track you E30 M3, this is an essential upgrade and until now was extremely difficult to source. Do not skip this pivotal step in your engine build or overhaul and get a leg up on the competition the Group A way.
Please note this kit is special order and in non-returnable

Features:

  • Kit replaces all engine pulleys and crank damper
  • Includes 6 rib serpentine belt
  • Underdriven waterpump and alternator pulleys
  • Recommended for off road and racing use only 

This kit fits the following BMWs:
1986-1992 BMW M3 All
