REAR ADJUSTABLE CAMBER ARM SET - STREET
Top seller! The Turner Adjustable Rear Camber Arms: The Only Adjustable Arms Approved for Grand-Am Continental Tire Challenge Racing Series

Why you should use Turner Motorsport camber arms on your car:

• If you have a lowered car and have run out of adjustment with the stock camber arms.
• If you have a track car and are looking for increased camber adjustment, lightweight pieces, stronger components, and improved suspension handling
• Two bushing styles to meet your needs: solid rod-end for track-only use (See T#304098), or rubber bushing for mixed street/track use (approved by Grand-Am!)
• The high range of adjustment allows a full racecar setup or a heavily lowered car to maintain factory specifications.
• Only high quality and high strength materials and components are used
• Aluminum camber arms are designed as a lightweight component, thereby reducing wear and tear on other, more critical parts (rear subframe, control arm bushings, etc). Each camber arm weighs only 2.5 lbs making for a total of 5 lbs for both parts! Stock camber arms weigh 3 lbs each. We have seen competitor's arms that weigh twice as much!
• Hardcoat anodized aluminum, stainless steel turnbuckles, and stainless rod ends to all but eliminate corrosion from getting into the threads and making adjustment difficult.
• CNC-machined double shear design for ease of installation, high strength, and choice of outside bushing material. But we do suggest using with (outer bushing # 33326775551) for best performance.
• Easy adjustment - our main adjustment point is on the outside by the wheel so there is no need to work around the exhaust or subframe to adjust camber.
• All hardware included.

TURNER MOTORSPORT CONTROL ARM MONOBALL BUSHING UPGRADE (FCAB)

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.

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?
