Cusco Adjustable Rear Lateral Control Arms

Cusco Adjustable Rear Lateral Control Arms - GR86 / BRZ / WRX

Precision Camber Alignment & Enhanced Suspension Geometry

Take full control of your vehicle’s alignment with the Cusco Adjustable Rear Lateral Control Arms. Designed for lowered vehicles and dedicated track builds, these arms replace the non-adjustable factory units, providing the necessary range to correct or optimize rear camber settings. By allowing for a precise "turnbuckle" style adjustment, Cusco ensures you can achieve the perfect tire contact patch, whether you are trying to save your tires from uneven wear on the street or hunting for tenths on the track.

What’s Included in the Box:

- Pair of Adjustable Rear Lower Control Arms: Includes both Driver and Passenger side units.

- Heavy-Duty Pillowball Bushings: Pre-installed for immediate suspension response and zero deflection.

- Adjustment Hardware: Precision-threaded turnbuckles with locking nuts.

The Cusco Advantage

- Extended Camber Adjustment: Offers a wide range of adjustment (+15mm to -15mm from factory length), allowing for approximately +/- 3.0 degrees of camber change depending on your ride height.

- High-Strength Steel Construction: Engineered to withstand the extreme lateral loads of high-grip tires and track use without the flexing found in stamped-steel OEM arms.

- Pillowball Joint Technology: Unlike factory rubber bushings that "squish" under load, Cusco’s pillowball joints provide a rigid, mechanical connection to the subframe, resulting in much more predictable handling and "on-rails" steering feel.

- Turnbuckle Adjustment: The arms feature an easy-access turnbuckle design, allowing for precision alignment adjustments while the car is still on the scales or the alignment rack.

- Signature Cusco Blue Finish: Finished in Cusco’s iconic corrosion-resistant blue powder coat for long-term durability and a premium look beneath the car.

Precision Tip: This is a "must-have" companion part if you’ve installed lowering springs or any coilover system. Lowering these cars more than 1 inch will typically result in more negative camber than a street tire can handle. After installing these arms, a full four-wheel alignment is mandatory. We recommend telling your alignment tech to aim for -1.5 to -2.0 degrees of rear camber for a perfect "fast road" setup that saves your tires.
