SPM Lower Control Arm Shim Kit

The SP Motorsports Shim Kit provides precise camber adjustment for the 996, 997, 987, 981, and 718 platforms. These platforms use unique control arm geometry that requires specific shim profiles for accurate adjustment.

Our shims are CNC machined to match the control arm interface and ensure proper fitment. Each shim can be stacked in different combinations to achieve the desired camber adjustment. The GT-style design provides OEM-style fitment while allowing greater suspension setup flexibility. Each shim is machined from 6061 aluminum for strength and durability. A tight 0.1mm thickness tolerance ensures consistent and repeatable adjustments during installation.

Whether you’re setting up your car for the street or track, this shim kit provides precise control over front and rear camber.
