Front Control Arms for BMW Z Series E85/6 (2003-2008)

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Our experience with spherical front control arm�ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).��We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren�t satisfied with the other options out there.� Instead of a Delrin bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have.�While race-ready,�our hybrid Delrin/monoball control arm bearings are more at home on the street than other kits that are advertised as��race-only� bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even�those found in the M3,�allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. �This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.� This unwanted deflection�stands between you and a crisp, confidence-inspiring driving experience. �The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing�complete freedom of movement�in the desired angles. What you get is superior steering precision with better handling from more consistent alignment�and direct braking feedback, with exceptional service life.� Thanks to the�Delrin insert and double lip seals, there's none of the extra noise or reduced service life�often�found on�other�spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

Features:

Bearing housing

• Manufactured using 6061-T6 blue anodized aluminum with a pre-installed grease fitting and grease distribution channels making this a serviceable design
• Knurling allows for a wide variance in lollipop dimension, although this particular SKU comes pre-installed, so you won't need to worry about that.�Want to install your own? Click here.�

Bearing

• A high quality greaseable double lip sealed bearing with Delrin� inserts. Delrin� was chosen due to durability�under pressure, while still soft�enough to create a perfect play-free fitment on the control arm.
• Replaceable for infinite service life - no need to replace the entire mount in the event a bearing happens to fail.

Includes new hardware. Grease before installation and with each oil service with high quality Moly grease for maximum service life.�Need a grease fitting tool?

Installation is relatively easy - see our instructions here.�
