Turner Motorsports Performance Adjustable Front Lower Control Arms

Fits RWD models only, does not fit xDrive models

The stock Genuine BMW front "lower" control arms (31108095665 & 31108095666) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics.

In order to address this issue, Turner now offers new Performance Adjustable Front Lower Control Arms! These control arms offer multiple benefits over stock control arms, helping to keep your BMW under control and on the track. 

In order to get the most out of your BMW M3/M4, these new control arms provide roll center, camber, and track width adjustment to dial in your alignment for optimal handling! Additionally, the ball joint angle has been corrected to allow for full articulation. Stainless Steel spacers are provided to correct roll center for lowered vehicles. The use of FK Rod Ends and High Misalignment Spherical Bearings eliminates the flex and binding found in the OEM control arms while allowing smooth articulation.

Another great feature of these control arms is the Double Adjuster Lock Down. This allows camber and track width settings to be adjusted and locked in without the use of finicky jam nuts. This double adjuster is machined from 4130 Chromoly; gun-drilled to reduce weight, then electroless nickel plated for corrosion resistance.

A ride height sensor bracket is also integrated to maintain factory ride height sensor location, regardless of the length of the arm to keep BMW's chassis electronics happy.
