This Eibach adjustable front sway bar was originally designed for the E9X M3 & E82 1M - But we've found it works extremely well on ALL rear wheel drive E9X 3 series (325i, 328i, 330i, 335i & 335d). Also fits 2008, 2009, 2010, 2011, 2012 or 2013 model E90/E92 M3 or 2011 1M Coupe, and features:
- German-engineered upgraded performance sway bar. Truly Tunable & better than stock!
- Precision hi-tensile steel alloy, cold-formed, tempered, and shot-peened for long-lasting performance and durability
- Tubular bar design for rigidity with less added weight
- Urethane bushings included that last longer and perform better
- Perfect complement to lowering sport springs
- Includes Eibach's Million Mile warranty
As used on our Project E90 335i Sedan! You can tune your E9X 3 Series (E90, E91, E92) or E82 1 Series handling by adding this 3-way adjustable sway bar featuring a stout 29mm diameter. While pre-set pair of front and rear bars from the same manufacturer can give you optimal handling balance, you may find the need to tweak your car's handling by using an adjustable front bar, but retaining the stock rear sway bar. This is particularly common for street use, where you may want improved turn-in, but don't want the added install time and expense of a rear sway bar (which are decidedly more difficult to install than a front sway bar).
This larger adjustable front bar dramatically improves turn-in and steering feel at lower speeds. You give up some performance and handling at higher speeds and the balance of the car will push the car into understeer sooner. But the front-only option remains popular on street-driven cars that rarely see the handling limit. For those cars, we simply recommend upgrading the rear bar to compensate.
This front sway bar kit includes a 29mm bar with
3 adjustable end positions. Changing the end link hole position allows you to further fine-tune the handling to better match your other suspension settings or wheel/tire setup. Set your sway bar link to the inner-most hole for the stiffest setting; the outer-most hole for a softer rate.
