BMW Engine Parts for BMW E30 M3 S14 2.3L

Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or over heated engine due to a bit of simple overlooked maintenance. This kit includes the belts and tensioner bar.

Fits the following BMWs:
1985-1991 E30 BWM M3

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.
