$30 E90 M3 rear guide rod, camber control arms came in, but for ONE side. LoL
Online shows only these numbers for sale. I'll call and ask if they have the other side.
Centric is the brand but I'm sure someone is make them for the brand. Someone who makes them for OE BMW supply 😃

I got these from CariD.com which also sells on eBay

SKU: 202591791

Centric® 622.34854 - Premium™ Rear Upper Rearward Control Arm

SKU: 79240620

Centric® 622.34855 - Premium™ Rear Upper Forward Control Arm

Excellent find, they appear to be reboxed TRW arms with the M logo removed. Let us know if you figure out the other side - the catalogues I looked at suggests it's the same arm for both sides when the actual BMW part numbers are different

You CAN push the bushings out on spindle, King pin side and flip them.

I will try that with OE first and see how it goes. I have access to press.

Just called that number for Centric, got to product guy quickly. He says his system is wrong and keeps saying same part for left and right. He will ask his suspension guy tomorrow to check it out and email me back. I'll call to follow up.

Looking at this thread, (CORRECT direction on install), one can technically FLIP the arms and have them work just the same!

However, the reason that forward guidrod arm is bent downward is for crash protection. It will bend and then break downward and away from the fuel tank.

So two of each are all that's needed for the rear?

[The Nightman]

Centric 622.34854 is the LHS wishbone (33322283545, curves upward)
Centric 622.34855 is the LHS guide rod (33322283547, curves downward)

You'll need:
33322283546 - RHS wishbone
33322283548 - RHS guide rod

With that said, I'm not sure how much there is to gain by replacing the wishbones. The guide rods are worthwhile though: https://www.1addicts.com/forums/show....php?t=1079383

Thanks man! That thread is what motivated me to install the Group N toe arm bushings.

Here are some photos I took comparing the Centric-boxed TRW guide rod to a TRW one. They are the same thing but the Centric ones were manufactured in 2013. Here is my feedback on them after installation

Looks like you had to purchase a TRW Right guide rod along with a Centric Left guide rod (622.34855). I assume Centric doesn't carry RHS guide rod?

Where is this arm going on the rear? Is this in place of the OEM toe arm in the very rear?

Replaces the guide rod (#19) or "front upper" control arm

Ok. I thought you guys were talking about 14.

I have the M3 rear control arm set. I'm good.

For rear toe, based on the sub frame you run (M3 or non-M), get adjustable toe arms with ball joints. Preferably something better than Megan. I have Megan and I worry about corrosion due to cheap paint that comes off easy
