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

The +0.25mm sizing indicates that these bearings are intended for use with a crankshaft that has been machined down by 0.25mm. This is common when rebuilding an engine to ensure proper clearances with the main journals.

What is the advantage of a bimetal aluminum base construction?

A bimetal construction, often with an aluminum base, offers a good balance of strength and conformability. This helps the bearing to properly seat against the crankshaft and absorb shock loads while providing good wear resistance.

Do these bearings come with installation instructions?

While installation instructions are not included with this bearing set, it is highly recommended to consult the manufacturer's official service manual for your specific vehicle or engine application for proper installation procedures and torque specifications.
