Just remember no one ever said "thanks to this $200.00 set of bearings I won the race".

The chance you would notice the performance difference is slim to none. I dealt with this in my machinery buying super high end bearings that were supposed to last longer and greatly increase performance. Most of the time they lasted the same or less and no performance increase was notice. I did have some critical applications the required bearings with very little tolerance, but that's a whole different basket of cookies.
