What does 'standard size' mean for these bearings?

Standard size bearings are meant to be used with a crankshaft that has not been machined or ground undersize. If your crankshaft has been previously repaired or worn beyond its original specifications, you may need an undersize bearing set.

Are these bearings suitable for a daily driver?

While these are race main bearings, they are well-built and can be used in a high-performance daily driver. For a standard, non-performance application, a regular replacement bearing might be more appropriate, but these will certainly hold up well.

What is the main advantage of using race main bearings?

Race main bearings are typically constructed with tighter tolerances and more robust materials. This allows them to better handle the increased stress, higher RPMs, and greater oil pressures often found in performance and racing engines.
