OEM rod bearings vs Aftermarket Clevite rod bearings

At 65K miles, I am looking to replace my 2008 E60 M5 rod bearings soon. Generally, I am an "only OEM" guy. But since the rod bearings of the E60 M5 are one of the weak points of the S85 engine, I am inclined to go for the aftermarket Clevite rod bearings with added clearance and more oil lubrication. I'd love to hear some recommendations from anyone with knowledge/experience. Thanks.

Thank you for the reply.
How are the BE bearings better? More clearance? Better materials?
Have you had yours replaced with those? How long has it lasted you so far?

The BE bearings were still under development when I replaced mine. So I went with the WPC treated OEM bearings, which seemed to be the best option at the time.

If I have do it today, I will go with the BE bearings.

Seconded


I'd go with BE bearings, replaced mine at the beginning of this year and for me, BE bearings where the only logical choice.

Any noticeable difference when you drive?

OEM Bolts will work fine if you want to save a few bucks skipping the ARP BE spec bolts. BE Improved bearings are the way to go though

On a side note
- If you are doing this yourself, then ARP BE Spec bolts will save you a lot of time on retorquing since it's once and done, vs x3 for OEm bolts
- If you are going above basic bolt ons, then ARP BE Spec bolts wouldn't be a bad investment for forced induction or much higher horsepower on the motor, otherwise OEM will handle just fine

I will likely go with BE bearings and ARP when I go in for my second set of bearings.

1st set of OEM went 84,000ish
2nd set of OEM are at 64,000ish
