What does the +.25mm sizing mean for these bearings?

The +.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to achieve proper bearing clearances on a worn or reconditioned crankshaft.

What is the Silvercore material?

Silvercore is King Engine Bearings' proprietary tri-metal material. It's a copper-based alloy designed for high load capacity and durability, making it suitable for performance applications and engine rebuilds.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are well-built and feature a material designed for extreme load capacity. They are a solid option for stock engine rebuilds, especially for BMW models known for their performance.
