After payment capture, cancellations and refunds generally incur a 5% processing fee, except for our error, confirmed defects or confirmed carrier loss. The 5% and 20% fees do not stack; only the greater applicable fee applies. Store credit waives the 5% fee, but applicable return fees remain.

The GKTECH Super Lock front lower control arms simplify, improve and replace the front lower control arm and caster rods on the FR-S / GR86 or BRZ, while also supporting around 65+ degrees of steering lock.
These arms are designed based off CMM data, they are CAD designed, FEA tested, have CNC machined ends and the main body is laser cut and bent from 4130 Chromoly Steel.
Adjustable, at their minimum length they start at +40mm over OEM and adjust out to +70mm from OEM (also available in an OEM length through to +30mm)
Designed with the OEM knuckle in mind, meaning they will work with our bolt on steering kit which uses the OEM knuckle.
We still use, as we do all our arms, common sized PTFE bearings throughout the arm, which can be found locally, however, we do have them on the shelf should you wish to carry spares. We also use our high misalignment rose/ heim joints to allow the arm to rotate freely.
Dust boots to protect the rose/ heim joints are included and have lock stops built into the arm for those that want to dial down the fun.
Finally, the arms are E-coated (electrophoresis coating) for rust prevention.
