Really? Care to tell that to the guys with 120k+ on their cars?
BE bearings are a BRAND NEW third party component that has yet to prove itself.
Supporting the eager early adopters is one thing, but telling an uninformed visitor to install them because he has over 65K miles is another.
Stop the paranoia indeed
The Clevite Tri-Metal design of the BE Bearing is not "brand new." It's the same Tri-Metal design BMW used in the S85 M5 engine from the factory. There's only two things about the BE Bearing that you might consider "new:" 1) the TriArmor coating. 2) the extra clearance.
The TriArmor coating has been around for a long time, maybe 15 years or more. It's just not used on a BMW bearing before. Most people swear by Calico coatings. If they swear by Calico coatings, then they should swear by the Clevite factory TriArmor coating even more because it's designed to be used with the bearing itself, not sprayed on after the fact like a Calico coating.
The extra clearance may sound new, but it really isn't either. Dinan, RD Sport, Van Dyne Engineering, and other engine builders have been using this extra clearance on the S65/S85 since the first stroker motors were built. The extra clearance specifications they swear by are well established engineering rules that go back at 60-80 years. So there's nothing new about them, or using them on the S65/S85 either.
What is new is putting it all together into a single package and calling it "BE Bearings." Clevite still makes them. Clevite still added the TriArmor coating.
Then pick one of the other options. Heck, if BMW had a competent parts department I'd have happily put OEM bearings back in mine...
There's only three choices on the market: 1) BMW bearings; 2) VAC Clevite bearings; 3) BE Bearings.
The BMW bearings are known deficient in all the ways being discussed and documented here and on other car forums. The VAC bearings don't seem to have any provenance behind them. VAC couldn't even tell you the specifications until I measured them and found what they told me was wrong. Ever since, they've advertised their bearings as extra clearance. But it's hard to tell what, if any, of their own work they put into their bearings. Did they just use all of my measurements without any testing of their own? Did they carefully review the blueprints Clevite provided and blindly accept the first blueprint they received? Are they doing any in-house testing with sophisticated measuring and data logging equipment? Why did VAC choose Calico coatings instead of spending an extra few cents to have the better Clevite factory TriArmor coating used instead? Was offering the cheapest part really that important? I've seen others on m3post ask these questions and VAC has never provided any answers. That's why I say if you are risk adverse, the VAC bearings would be your last choice.
Besides OEM, the only other viable choice would seem to be BE Bearings. They are designed by Clevite, manufactured by Clevite, and coated by Clevite. BE Bearings literally measures every single bearing for 100% quality control. BE Bearings has them in their own test car with some pretty sophisticated measuring and data logging equipment. BE Bearings is making all of the data logs open source, for anybody to download and analyze (hundreds of megabytes of data).
Nobody else provides this much work and this much data to prove and back up their product.
