Track guys...BE or WPC?
I know this topic has been destroyed to seat in the other thread. I just want to know which ones you guys have personally went with. Don't really spend time in the other sections of the forum.

I used BE bearings and BE ARP rodbolts. 2 track days so far. Service interval for going in and looking/replacing them is on my list of things to think about. I put a lot of street miles on the car, so that factors in as well. But maybe two years or something.

I went BE based on feedback from other track junkies. I just had it done and haven't been to the track with this car yet.

I have BE bearings and BE-ARP bolts on both track M3s. I don't see any good reason to do differently |

Aren't several of these bearings just made by the same company anyways, and it's just a matter of rebranding or additional tweaks being done?

WPC are OEM bearings made by Clevite (not sure of the tin/alu ones were but I believe the originals were). These slightly increase clearance and were a good option back when there were no specific increased clearance bearings VAC are made by Clevite to the 'VAC spec'. I shuddered a bit writing that. VAC has changed their tune several times as to what exactly this bearing is, but currently they say it's increased clearance. BE bearings are made by Clevite as well. BE has all the info published right here and their spec is different than the rest. They're the only ones who have 'industry standard' clearance. In terms of clearance there's OEM<OEM+WPC<VAC<BE |

VAC adds their own coating to the bearings which makes it close to OEM spec... doesn't really increase clearance.
Still way better than WPC - VAC uses softer lead/copper bearings so should they wear, it won't be as bad as the treated OEM hard aluminum bearings that WPC has. BE Bearings are the only ones that actually increases clearance.

Plus there are ACL. Many racers of older BMW use ACL bearings. I don’t think you can go wrong with any of them. The biggest risk is leaving your original bearings in the motor.

Go with either VAC or BE. WPC is inferior to both as it is retaining the same bi-metal (tin/aluminum construction) with minimal clearance gain.

I assume those are also made by Clevite?

Previously vac was coating factory bearings and selling them in the replacement kit. Vac now uses the same Clevite 77 bearing that BE does, vac come with coating as well the BE do not. I've installed both now about 10 times and have yet to see a complaint from any one after the job was complete. What I did notice is the tq specs are different I've see some call for 50lbs while others have called for 45 from vac. just my .02 it doesn't matter which you choose they both offer better clearance then stock.

ACL is a separate company. the three main bearing companies I've seen are
clevite King and ACL.

ACL appears to be another company. It's clearance seems to be the same as the VAC ones, so more than stock but not as much as 'industry standard' which is BE
