What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.

Clearance specifications for the 5M1573H main bearings depend on your specific engine build and intended use. It's crucial to consult with your engine builder to determine the appropriate clearance based on your application, as this can affect performance and reliability.
Are the 5M1573H main bearings suitable for street use?
While the 5M1573H main bearings are designed for high-performance and racing applications, they can be used in street applications if the engine is built for performance. However, keep in mind that they are optimised for high-stress conditions, so ensure your overall engine setup is compatible.
What type of oil should I use with the 5M1573H main bearings?
For optimal performance with the 5M1573H main bearings, use a high-quality synthetic oil that meets the specifications required for your BMW N63B44 or S63B44 engine. Proper oil viscosity is critical for maintaining bearing clearance and ensuring reliable operation under high loads.
