Which RTAB would you buy?

I need to replace my RTAB's and am having some trouble finding the sturdiest one of all:

Lemfoerder PN 33326770786

(Half/Half casings)

Lemfoerder PN 33322228153

(Single casing)

OEM M3 PN 33326770817


Meyle PN 33322228153



I'm noticing that there are models with "split casing/housing" and others in "full casing/housings". See attachment... I'm guessing that the full housing will retain the rear-toe more in spec during heavy cornering and acceleration?

I don't want a flimsy floating feeling, what is the recommended RTAB?

Thanks

I would highly recommend either the OEM M3 or the Meyle HD, part # 3003332104/HD, which uses a similar construction. Note that this Meyle part number is different than the one you listed above - not sure but that may be the old BMW part number that you listed. The flanged design is the older design that BMW has moved away from, the split casing is the newer design. When installed, the 2 halves of the casing are squeezed together compressing, and stiffening, the rubber interior.

You won't have a flimsy floaty feeling with either of the above recommended new bushings but if you want additional toe control that will also help the bushings last longer, I would also recommend that you pair them with a set of Vorshlag limiters:

I'm running these limiters with OEM M3 bushings and it's a great setup.

I think I will go for the Meyle HD (3003332104) and as backup the OEM M3 (33326770817). The UUC's are just too stiff for my huse and I don't want to deal with the possibility of creaks.

For some reason, autohausaz.com only shows me the Lemfoerder M3 bushings and not the OEM ones. Does anyone have recommended places for the Meyle HD RTAB's?

I'd recommend the lemforder M3's over the Meyle.

Meyle HDs with the Turner Motorsport Limiter kit.

I have this setup and I love it.

For the Vorshlag limiters, are these just plastic washers that go at the ends of the RTAB's WITHOUT any drilling?

Thanks jpr. PelicanParts shows the Lemforder M3 bushing as the old PN 33322228153 and the old single piece housing. What do you think?




And the OEM M3 from PelicanParts (33326770817)

The Vorshlag limiters require no drilling, they just wedge into place. IIRC, they are also quite a bit cheaper than the Turner limiters and every bit as effective.

Don't get the old style one-piece flanged bushing. I ordered the new style M3 bushing directly from Tischer.

I'm with TxZHP04 on this, might as well get the new style (the -817) bushings. Attached is what the ETK shows for part number history on the M3 RTAB's

Thanks, just placed my order for the Vorshlag limiters.

What about Powerflex RTAB? Don't the M3 RTABs breakdown overtime, like usual OEM e46 RTABs?

Thanks for the suggestions. I placed my order with Ruben at DesertMotorWorks.

The Powerflex are just a tad too stiff for my daily drive (about 100-150 miles per day).

Yes, and powerflex squeak requiring them to be lubed periodically. Either way, you have routine maintenance. I've had urethane RTABs and switched back to OEM M3 bushings with limiters and feel this is the superior solution.

Regarding the orientation of the slot, here's the TIS instruction on bushing replacement.

I must be a little slow today... can't tell if the orientation is vertical, horizontal, or slightly at 70 degrees compared to flat ground.
