M3 Control Arm upgrade?
This car is my DD with 119k kms. My thrust arms are worn. I'm debating upgrading to the M3 components as many do, since I need to replace the thrust arms anyways.
Question to those who have performed this upgrade in the GTA: Did you notice any negative outcomes (NVH) after installing given how fucking terrible our roads are? (esp in the core) I don't track this car - should i just keep it stock? Any input would greatly appreciated. Thanks in advance |

Go back and look at some old posts of mine (in the suspension forum, on mobile not easy to look up right now), I had a 2010 128i Sport package car, and I did the M-control arm upgrade up front (2 per side). The impact harshness went up significantly after the upgrade. Sure the feedback and feel were great but I hated the sacrifice, and the upgrade to me wasn't worth it.
Some people say it's the tension strut arm that has most impact in ride harshness. I can't confirm or deny that...but...I hated the final result. If you're not tracking and/or were happy with the feel prior, just go with OE replacements in my opinion. |

It’s definitely the thrust arms that add NVH. Controls arms add camber and zero NVH. I switched my M3 thrust arms back to stock because I couldn’t handle the NVH they added. My stocks recently wore out and I went with Meyle HD replacements. They are a good compromise between soft stock and too stiff M3.
