What does the +0.75mm size mean for these bearings?

The +0.75mm sizing indicates that these bearings are intended for use when the engine's crankshaft journals have been machined down by 0.75mm. This is a common practice when rebuilding an engine to correct for wear or damage on the crankshaft.

What are the main benefits of the lead-free composite material?

The lead-free composite material is an environmentally safe choice. It's designed to work well in medium-load engines, providing reliable performance without the use of lead.

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

These bearings are described as ideal for medium-load engines. For high-performance or racing applications, it's always best to consult with a performance engine builder to ensure the chosen bearings meet the specific demands of your build.
