But yeah, whiteline have a decent reputation. But not much experience in our platform which should also be a consideration. Most people (myself included) just upgrade to the M3 sways and suspension components. |

I'm looking at Whiteline because I have access to them at good prices and the following comparison.
http://www.turnermotorsport.com/t-te...sway-bars.aspx I assume Whiteline uses a 27mm "solid" section so the results should be similar to the H&R. If the comparison by Turner Motorsports is correct that's a huge improvement over stock. Even compared to the M3 bars. |

But what does a 'huge improvement' mean to you? Thickness? And does thickness of sway translate to better handling? i.e. understeer or oversteer? The M3 gets its praises from being a well balanced and handling machine, not from its power. That said, everyones driving style is different and it's about setting it up to what you want and your style. |

As to if it will induce over or under steer, that completely depends on how much thicker/heavier the new sway bars are. If the front upgrade is disproportionately bigger than the rear, or only the front is upgraded, then an otherwise well balanced car will tend to under steer. Do the opposite (rear sway bar increase) and the car will tend to over steer. That being said, how firm the suspension is and tyre selection play a large role as well. |

I was also going to ask what the percentages in that chart actually represents, what are they measuring in that comparison? % stiffness? % increase in speed around same corner?

% quoted are increases in stiffness.
The higher % figure is not necessarily 'better', as a high % increase in stiffness can produce a lot of oversteer and the handling become twitchy and snaps and bites hard (not what you want for an inexperienced driver) TBH I would stick to the M3 items, as they're a safe compromise and at the end of the day oem items so it keeps the insurance guys happy also |

If you stick to the speed limit and don't do anything funky around corners you'll experience little difference with sway bars except less body roll and sharper turn in.
I put an upgraded sway bar on a Saab 9-3 coupe once - not the most dynamic of cars but nicely balanced (despite what you read) - once the stiffer rear sway bar was installed (about 30 minute DIY job) the car felt like it was oversteering into every corner (even though it wasn't actually oversteering) until I got used to it - about 30 minutes of driving will get you used to a car. Note that a stiffer sway bar will effect the DSC effectiveness on your BMW - if your prang your car and your insurer figures out you have a non-spec sway bar it'll open all sorts of conversations leading to no coverage (depending upon the value and nature of the claim); the way around the insurance problem is to report the modifications to your insurer. I'd suggest that if you have a non M-Sport suspension then I'd suggest you just add M-Sport sway (stabiliser) bars but the cost of BMW parts might mean a lot of dough for not a lot of benefit and if you have M-Sport suspension then choosing M3 sway bars (assuming they fit) might be the go.

I have both Whiteline sway bars installed, and can confirm all that has been commented here. I have the stock sports suspension. Body roll is reduced and turn in is improved slightly. But the car has become rather unpredictable at the limit, over steering easily. I made the upgrade because I was replacing the rear sub frame bushings, so might as well upgrade the rear sway bar. And I chose Whiteline because I was told very good things from them and the fact that I'll be installing coil-overs very soon (and have read that the coil over will go nicely with stiffer sway bars, as long as springs are stiffer).
Now I have to hurry and save for a LSD, because now it will be required to keep traction. If not done soon, I'll be changing to the M3 sway bars. |
