This is a must-have for ALL BMWs, and simply installs in place of your existing drain plug. With every oil change you perform on your BMW, you'll be able to inspect for metal shavings and debris. Many times, if something is going wrong on your BMW's engine, the magnetic drain plug can give you an early warning. Our championship race team uses this info all the time (Ever find a piece of a valve spring in your oil? We have!) Be sure to get one now, and make the swap next oil change!

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
