Definitely do the rear subframe bushings at the same time, it makes a huge difference and you have to drop the whole subframe at the same time to do the rear bar anyway. I have just written a review on this... search posts by me. You'll love this change. Also, while you are doing this... replace the rear M3 control arms too - there are 2 of them. And yes, get a four wheel alignment. I am going to the dealer for that.

I'm not sure why an alignment is due, the bars should NOT change the angles under normal driving, or ? Last edited by DaanBMW; 08-01-2011 at 02:48 PM.. Reason: typo |

I have just done this conversion on my 335i and I noticed two things:
1. the ride is a lot harsher than before and 2. the car sits higher at the back. is this normal?

Did you preload the suspension before you tightened the arms?

Thanks for the replies.
I had the front tension arms and wishbones changed, rear bushings and both anti roll bars. I did not do the work myself. What exactly is preloading the suspension? *EDIT* The car is higher only on the left side. The right side remained unchanged. Last edited by cedchung; 02-27-2012 at 06:46 AM.. |

Preloading the suspension means that you need to have the the suspension in the same position as if the car were on the ground.

For the M3 lowering control arms and tension rods do they both affect the alignment or is it only one of these?
Basically I am asking can I install the lower controls arms or the Tension rods and then drive it to the shop where it will be aligned and have them do the remainder and alignment as well. Trying to save myself on labor. Edit: Looks like the tension rods don't change things much. So just to double check, the tension rods can be installed without replacing the lower control arms? That way I can save on labor and still get the car to a shop to finish up the job and align the thing? Last edited by acdHQK713K; 02-27-2012 at 06:16 PM.. |

2 hours in labor for the tension rods seemed excessive to me. |

I am in the process of picking up a E92 M3 front sway bar. Is there a great benefit to just putting the front sway bar on (will I notice a difference)? Or should I wait until I get the rear sway bar and the front strut bar, and do the install at the same time?
Thanks!!

I did Dinan Stage 3, (Dinan camber plates, springs, shocks, M3 front arms (2)) - it is recommended that you do NOT do the rear bar UNTIL you have an LSD installed. This is due to the fact that you might loose traction in the rear. Search some threads on this. This is what I followed anyway, I did the rear as a separate stage - rear DINAN bar (to match my front), rear subframe bushings, my Wavetrac LSD, rear M3 control arms- upper and lower - and then I added the rear toe arms. Search some threads on this.

Got the tension struts on in 45 mins.
Very easy. Car feels driveable. I will let the alignment shop do the rest later this week. A ratcheting 21mm wrench sped up the process. Torx T40 was needed to keep the stud from spinning on the tension rod to steering knuckle connection. |

In that case no, the suspension was definitely not preloaded. Everything was tightened while the car was on the lift.

You don't have have any preload on any of the rubber bushing control arm ends. Vehicle must sit on its own weight before securing the suspension control arm bolts.

My car is still sitting higher on the left. I know it is normal for it to be up to 10mm higher but I measure both sides and I am getting a 15mm difference at the rear! What could be causing this? Can the rear anti roll bar be off centered?

I hate how the suspension is so sloppy. There is just way too much travel compared to my E92 M3. Good thread
