Introducing the Cup-Series lower control arms for your Porsche 996/997/986/987/981 & 991. Much more than just another billet replica of the GT3 arm, this design is superior to any other aluminum arm on the market.
Starting with the unique ball joint design. For safety, the problematic 12mm ball joint design, used on both OEM and other aftermarket arms, has been completely redesigned for a full proof, larger, significantly stronger and more reliable design that you can count on. The ball joint consists of a replaceable oversized precision grade Teflon lined monoball bushing. Roll center geometry can also be adjusted to correct for lower ride heights. High misalignment bushings provide safe and bind free operation at any ride height.
Solid thrust arm bushings and sealed monoball inner ends eliminate the spongy rubber OEM bushings and provide a precision ride for improved feedback, steering response, and overall handling. Both are CNC machined from 6061-T6 aluminum alloy, and are anodized red for a corrosion resistant and attractive finish. The solid thrust arm bushing is adjustable for increasing or decreasing wheelbase, and adjustable caster.
Camber and track width can be accurately and repeatedly adjusted with precision GT3 style shims. A time competition proven design that allows for up to 20mm of adjustment per side, and up to an additional 2 degrees of negative camber.
With the optional adaptors and Litronic bracket (If needed) each kit comes complete for one axle with all parts and hardware necessary for a bolt in direct replacement for the OEM arms.
