Cup-Series Control Arm Kit (GT3 Rubber Spec)



Introducing our new GT3 Spec Cup-Series lower control arms for your Porsche 996/997/986/987/981 & 991 (not GT4 or 991 GT3). Now certified by PCA & POC as a class legal substitute for the NLA OEM Porsche 996 GT3 arms.  Much more than just another billet replica of the GT3 arm; this design is superior to any other aluminum arm on the market.
For safety, the problematic 12mm ball joint design, used on both OEM and all other aftermarket arms, has been completely redesigned for a fool proof, larger, significantly stronger and more reliable design that you can count on. The ball joint consists of a replaceable over sized precision grade Teflon lined monoball bushing.  High misalignment bushings provide safe and bind free operation at any ride height.
In addition to having the same geometry as the GT3 arms, rubber thrust arm bushings and inner ends are used to qualify this kit as a class legal substitute for the 996 GT3 arms.  Like the GT3 arms, the thrust arm bushing has two mounting holes for caster reduction on high camber applications.
Camber and track width can be accurately and repeatedly adjusted with precision GT3 style shims. A reliable competition proven design that allows for up to 20mm of adjustment per side and up to an additional 2 degrees of negative camber.
The inner and outer arms are CAD designed and machined from 6061-T6 aluminum for optimized strength and weight. It's hard anodized for a highly durable corrosion resistant finish. The unique rib design allows for easy access to the inner arm hardware, which is another problem with the OEM and other available arms.
