Show original supplier description

The GKTech adjustable Rear Lower Control Arms (RLCA's) offer significant adjustability for the rear multi-link suspension, enabling up to 55mm of track adjustment and motion ratio tuning. These arms can also be utilized to lower the vehicle's ride height by a fixed 25mm. Constructed from chromoly sheet and featuring TIG welding, these RLCA's are CAD designed and FEA tested for robust performance. Adjustability is key, with these arms allowing for on-car adjustments ranging from -10mm (shorter than OEM length) up to +45mm over the original length. The ability to adjust the motion ratio allows for varying wheel rates without needing to change springs. A provision to retain the headlight leveling sensor is also included, along with dust boots. Fitment is confirmed for Scion FR-S (ZN6), Subaru BRZ (ZC6, ZD8), Forester (SJ), Impreza (GP/GJ), WRX/STI (GE/GH/GR/GV, VA), and Toyota GR86 (ZN8) / GT86 (ZN6) models. Installation is straightforward, with many users noting the clarity of the included instructions and available YouTube tutorials. GKTech provides a lifetime warranty on suspension arms against manufacturing defects and a 1-year warranty on the Teflon lined rose joints, with spare parts readily available.
