What does the 0.25mm undersize mean for these bearings?

The 0.25mm undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.25mm. This ensures a precise fit and proper oil clearance when used with a reconditioned crankshaft.

What is the benefit of the performance coating on these bearings?

The performance coating helps to reduce friction between the bearing and the crankshaft. This can lead to less wear and improved durability, especially in higher-performance or harder-working engines.

Are these bearings suitable for a stock engine rebuild?

While these bearings have a performance coating, they are specifically sized for a 0.25mm undersize crankshaft. They are best suited for engine builds where the crankshaft has been machined to this specification, often found in performance or performance-oriented rebuilds.
