What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are designed for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to address wear or minor damage on the crankshaft.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes all the bearings needed for a specific engine application, such as for all connecting rods in your BMW's engine.

What is the benefit of the specialized overlay material on these bearings?

The specialized overlay material helps the bearings conform better to the crankshaft surface. This can lead to improved oil flow and reduced friction, which are crucial for proper engine lubrication and longevity, especially in a freshly rebuilt engine.
