Q: Do I need VAC Bearings?A: Unfortunately, you might... BMW will not disclose their logic as to why the build engines the way they do. Its up to engine builders such as ourselves to come up with ways to improve something with millions of dollars of R&D. S65s experience rod bearing wear on both street and track cars. See the used oil analysis image provided by a customer who is experiencing rod bearing failure under normal driving conditions! Even normal street engine use is leading to bearing failure at a much higher rate that expected.
Q: Why do VAC bearings do a better job?A: Our bearings are not only made with great precision and repeatability, but their coating is widely praised as one of the best upgrades on the market. Its a physical layer (not just a treatment to the layer) with both a high embedability factor, and a 'dry lubricant' property. What makes them so good is that they can run tolerances that BMW engines like and not see the typical failures that one associates with the OEM units. Unlike treated bearings that must be sized very close to OEM for proper results- these bearings have the ability to run well on both sides of engine tolerance and work fantastically for cold starts that street engines see, and race engines as well. All VAC engines are built with our coated bearings and we know they work gre
