I ordered the full control arm set.

And holy hell that thread is long and in-depth. Some serious technical discussion. A few times folks asked for the 'low down' on whether the upgrade to M3 or other control arms in back was worth it. It seemed to depend. You're both saying the uppers are definitely worth it and the lower can be avoided to save a few bucks. I ordered that kit. Now with the M3 RSFBs, new PS4S tires, and the control arm kit, what will the ride be like for a non-track person like myself? My biggest complaint with the stock set up, like folks I think, is that the rear gets unstable over bumps and the ride is too firm/choppy (esp with the RFTs). I have the PS4S on now and already notice a vast improvement. The suspension work is due to occur next week. While I have the control arm kit on order, I could really go either way.

As to the ride - it really depends how important comfort is to you. I think if you weren't too beat up with runflats and a stock suspension, with non-runflats and these mods you'll be happy. I think someone mentioned doing the front M arms in 2 stages to see how you like it (doing the wishbones first). The problem that is that you need an alignment each time. Some will say maybe not with just the tension struts, but I don't think so. (FYI - the car will be nearly undriveable with the new front wishbones without an alignment or some stop gap fiddling with the tie rods.)

Hey OP, seems like you got the price and place sorted out. Asked Wile Motorsport and said they would charge about that same amount (~$900) for the job so what you got there is a discount. Does that include alignment? The front control arm upgrade to M3 variants DOES make a big difference, even on a non-track guy that you are. It makes turn-in more precise and gives you more confidence in spirited driving. I know because I did these all at once-RSFB, control arms and coilover upgrade. The MSport is not bad at all, but after the upgrade you WILL be able to tell the difference, in a good way that is!
The front control arm upgrade is an easy DIY, take it from me, I’m a novice at these things! I was able to replace the WHOLE front suspension on one side at one point in my tiny little garage/ storage area (live in an apartment complex). I can’t say much about the rear arms and rods as that’s been a big debate as to the difference it makes. Sure, it does look good though back there w those M3 ones! Good luck w your upgrades @LuisBoston! |

Rear M arms make a big difference in the rear end "shuffle" you might feel over bumps.
I forget which one is the one that makes the most difference but I'm sure fe1rx's thread about the rear arms does conclude that not all replacements are really needed. |

The dealership's tech should have looked up the part numbers(realize they are M3 part numbers) and follow the proper instructions to install them.
