Clean sheet design conrod bearings for the S65 rod bearings & S85 rod bearings for S65B40 V8 and S85b50 V10 BMW engines as used in the E92 M3 & E60 M5. These bearings are manufactured in the UK to the highest quality by the very people who make bearings for F1 engines, as well as all other leading race series including Le Mans, NASCAR, MotoGP, WRC, DTM!

Nominal optimal clearance of 55micron (43 to 57 micron range) calculated using proprietary MAHLE Motorsport software that accurately predicts housing swell, bearings loads, oil film thickness and power loss. The same software is used to design Formula 1, Le Mans, NASCAR, MotoGP, WRC & DTM bearings!

Bearing Construction

MAHLE Motorsport S65 bod bearings & S85 Rod bearings are manufactured with high strength steel back with a cast bronze substrate and finished with a lead indium overlay, originally known as VP2. This unique structure gives a higher fatigue strength than other Race bearings along with better conformability. This exact material is still used in race engines in all major race series globally! This material should not be confused with other “tri metal” bearings. Other parts are sintered which gives a lower fatigue strength and use lead / tin overlay.

The ONLY Genuine VP2 material is from MAHLE Motorsport. VP2 indicates the cast bronze substrate with lead indium overlay. Do not be mislead by others claiming their parts are VP2 material – No other aftermarket bearings use this structure and no other manufacturer produces bearing for F1!

Laser Marking

All MAHLE Motorsport bearings are laser marked. Traditional stamping can cause bearing distortion and prevent efficient heat transfer to the housing leading to failure
