Why choose MAHLE Motorsport bearings for your S63 N63
Manufactured in the UK by the same specialists who supply bearings to Formula 1, Le Mans, NASCAR, MotoGP, WRC and DTM, these MAHLE Motorsport bearings offer exceptional fatigue strength and conformability for high load S63 and N63 V8s. We use these bearings in our own customer builds and servicing, and feedback has been consistently excellent for both daily-driven cars and hard-track-use M cars.
Race-proven construction
High strength steel back with a cast bronze substrate finished with a lead indium VP2 overlay. This unique MAHLE structure delivers:
- Higher fatigue strength than typical race bearings
- Excellent conformability and embedability
- Consistent oil film and stability under heat and load
Do not confuse these with generic tri-metal bearings. Many alternatives are sintered with lower fatigue strength and use a lead tin overlay. MAHLE’s VP2 lead indium overlay material is still used in top-tier race engines worldwide.
Optimised clearances for performance
Nominal optimal clearance of 55 micron with a 43 to 57 micron range. Clearances are calculated using proprietary MAHLE Motorsport software that models housing swell, bearing loads, oil film thickness and power loss, the very same tools employed to design bearings for F1, Le Mans, NASCAR, MotoGP, WRC and DTM.
