What does the 0.25mm size mean for these bearings?

The 0.25mm designation indicates that these bearings are undersized by 0.25 millimeters. This is used during engine rebuilding to help achieve the correct bearing-to-crankshaft clearance when the crankshaft journals have been machined undersize.

What type of engine is this bearing set designed for?

This set is designed for Subaru EJ series engines, specifically the EJ15, EJ16, EJ18, EJ20, EJ22, and EJ25. This includes naturally aspirated and turbocharged variants found in many Subaru and some Saab models.

Are these bearings suitable for high-performance or racing applications?

These bearings are described as ideal for medium-load engines and feature a bi-metal aluminum silicon base. While well-built, for extreme high-load or racing applications, you may want to consult with a specialist to ensure they meet your specific performance needs.
