What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.50mm. This is typically done to correct wear or damage on the original crankshaft journals.

What is the main benefit of a bimetal bearing with an aluminum silicon base?

Bimetal bearings, especially those with an aluminum silicon base, offer good compatibility with crankshaft materials and are known for their ability to handle engine loads. This construction helps ensure durability and proper function within the engine's bottom end.

Are these bearings suitable for a standard engine rebuild?

Yes, these main bearings are a solid option for an engine rebuild, particularly for the Mini Cooper B38A15M0. They are designed to provide the correct oil clearance and support for the crankshaft.
