Most affordable way to reduce body roll?
So I just recently picked up a 2011 e92 M-Sport and I love it, my only complaint is that the stock suspension scares me a bit at high speeds on these run flats.
I will be replacing the tires soon with some PSS or PS2s but are there any other affordable mods that will help reduce my body roll without going the full coilovers/bushings/etc route? The car pretty responsive my major issue is going 80mph+ around curves I can't get a feel for the road and have no clue where my point of no return is. Last edited by 335m; 06-13-2014 at 03:29 PM.. |

Stress? i havent read up on any? but its the best bang for the buck far as anti roll. Im on the oem bars and dont care much about beefing up with anti swaying department but on my previous car they actually did the most.
im sure someone who tracks will chime in soon.

I did a front bar upgrade, then increased the spring rate in the back. Both helped.
If you do sways....Front bar is easy labor, rear bar is more difficult. |

I just did a E93 M3 front sway upgrade yesterday. It seems to be doing a much better job keeping the car flatter through corners than the stock bar.

Anyone have first hand experience running Koni Yellows + H&R or Eibachs for an extended period of time? I see a lot of install reviews but nothing long term. |

PSS or PS2 tires will be your best upgrade for grip. Then dampers like Koni Sport or Bilstein HD. Remove the alignment pins on the strut mounts, maximize your front camber, use M3 toe specs and add M3 front control arms and front sway bar if you can afford them at the same time.

Keep in mind I haven't had but a few miles of driving time since the install but the front end definitely feels more composed, flatter in corners, and just tighter overall. The full kit from getbmwparts.com was only around $275 shipped and it took longer to drag the tools and ramps out of the garage, pull the bottom shield, and put all the stuff back in the garage than actually swap the bars out. I have the front and rear M3 arms and a BMW Perf. Suspension in the garage waiting to go in so this was really just stage 1 of my suspension plan for the car.

Perfect, thanks! I just put some bilstein HD on my non-sport springed e90. I am loving the upgrade, but thinking taking out that little bit of lean and making it more responsive in quick linked turns may be the next requirement. Good to hear you can do this yourself too, should make it a pretty economical improvement.

If the run-flats scare you at high speeds, swaybars ain't gong to fix it IMO.

Quick, inexpensive solution....nope. There are many things happening that need improvement, but first things first: Suspension inspection needed. Mileage? Shock condition? All that said, if bushings good and no other suspension issues, Koni FSD is a good upgrade. Figure $1k more or less. M3 front sway sharpens performance some. Avoid thicker rear sway w/o LSD. Did I mention LSD? A not inexpensive, excellent upgrade - hard to believe BMW cursed us with that stupid e-diff. Oy! |

Coilovers are another option. BC coils are a good deal. You can pick the spring rate, and adjust the stiffness. They also come with camber plates which are useful.

I am considering BC Coilovers due to the similar price point compared to Koni FSDs + springs, if these came with camber plates would I need anything else immidiately? |

Stock suspension is floaty and sway bars will not help going straight or light cornering. Change the springs and shocks first. I have done a lot to make this car how it should have been from the factory. Also, stiffening the rear subframe bushings makes a big difference for making the rear more planted and controlable under load.

Yup, the stock shocks don't have enough initial compression or rebound force.
