The BMW begins on sale now are made from a harder material than the old ones, which is counter intuitively not good, but it was the only way to go with the WPC treatment (due to suppliers)

My original bearings came out at 58K. One of the them showed wear but not too serious.

I can recommend Reddish (Bristol) lots of measurments and pictures provided
I had an ESS charger fitted so the ESS bearings were the natural choice. Honestly I don't know the clearance specs on them but I can't find any negative feedback on them anywhere on the net and ESS have over 1500 kits out there apparently so they seem like a good choice

Nice feedback from guys here.

My engine was replaced under extended warranty for a worn and spun bearing. I don't know how aware previous owner was about warm up and mechanical sympathy so can't provide a full picture.

The 60 grade oil is spec'd for good reason as FazerBoy has stated. If I was to get my bearings replaced i would go for the OE items and stick with the specified 10 60 oil and be strict with warm up so the oil had a chance to get to the desired viscosity.

I haven't looked into the aftermarket bearing options or treatments to be honest but I'm a natural skeptic. Just my 2p

I have been reading this document which led me to think if I were going to change mine I should go with larger clearance bearings. I am obviously aware that BE are bound to make a document that will lead me to think their bearings are better than the originals:

http://bebearings.com/Overview.html

Also I was speaking to two different independent BMW specialist that said they would change the bearings for new OEM parts but then recommend using a thinner oil.

One said:

A lot of talk about the clearance issues. I advise oem bearings and different oil. Biggest issue is the brake down of the oil as the Castrol stuff is just not up to the job over the std service intervals.

Another said:
Our recommendation and what all our rebuilds, and my own cars have used is
the new BMW bearings and run a better/thinner oil. The best oil we recommend
for road use is Fuchs Pro Race 5w40 or Motul 300v. For track use we
recommend Fuchs Pro- Race 10w50.

They both did say they would also be willing to supply and fit BE bearings but both recommended using OEM.

Exactly this. ^^^^

Clearances are fine when the engine is warm. Oem bearings and castrol 10w60 are the way to go. The amount of R&D that BMW put into the engine design is ridiculous. They know what they are doing.

The ESS bearings are Calico coated OEM bearings. In house, they have used a few sets of BE Bearings too. But the ones on their web site are Calico coated OEM bearings.

Which model year onwards did BMW upgrade them? 2011 onwards wasn't it? Anyone had any issues?

They weren't "upgraded". The material changed, but the clearance spec stayed the same.

I'll be having a look at one of my new shells later this month. It'll have roughly 5,000 miles on it and a LOT of track days. It'll be very interesting to see how its worn.

The only issue is the idiots that don't know how to warm a car up properly... nothing that bmw can do other than try to teach them a bit when they buy a car but even then most probably won't show any interest

I totally agree.

I also think that in a way all these pcp, lease and finance deals play a part. Nowadays how many people buy a car outright? The majority are leased in some form and handed back when the warranty runs out. So the first owner doesnít have a care in the world with regard warming their engine up. I also personally believe the service intervals are too far apart. The first owners (that donít and wonít ever actually ever own the car) are not likely to pay for extra oil changes! Us sad geeky enthusiast owners only make a small percentage of overall owners. And abusers!

Yep, why bother looking after a car properly, unless you intend becoming the owner at the end of the PCP. Why worry about looking after it properly in terms of servicing or caning it from cold.
The only thing you need to worry about is cosmetic damage, to avoid getting charged for that when you hand it back.

I agree two years or 20,000 miles is too long between oil changes on a performance car like an E92 M3.

it's made me far more aware about looking for the clues in the ownership and service history when buying a performance car these days.

A big proportion of cars are on PCP, for me that's a big proportion to avoid when I'm buying privately a few years down the line, unless I'm confident the car has been looked after.

Can't blame PCPS for bearing failure but the conditions PCPs create don't help IMHO.

Dcdad.

Wow, that will be very interesting to see shells with such low mileage! OEM bearings or aftermarket?

Looking forward to some pics and inputs mate!

So is there a benefit from changing to BE bearings with higher clearance or stick with BMW parts? And if sticking with BMW parts keep to the same 10W60 oil or as some specialists have recommended, go with thinner oil?

My choice would be oem bearings, 10w60 oil and resist stamping on the throttle until the oil temp needle is near enough in the middle

The Million Dollar Question mate which nobody will have a true answer to until further testing on the aftermarket shells.

After following the debate on M3Post etc during the last years I will personally go for aftermarket when it is getting time. VAC coated Clevite (rather then Carlio) or BE seems most appealing at this point but we'll see next Autumn. Regardless of reasons to the RB fail (or combination of), I think adding further slippery and or a tad more clearance will only be good, while staying with 10W60.
