The SPL billet lower control arm kit includes black anodized CNC machined billet 6061 aluminum lower control arms and 2024 aluminum trailing links that provide track width, camber, caster, roll center and anti dive adjustment.  This is the ultimate tool for setting up the handling of your Porsche 996/997/Boxster/Cayman chassis for racing, track or street use. 

No more jam nuts!!  Long gone are the days of fumbling with multiple wrenches to tighten jam nuts in place while trying to keep your bearings orientated correctly.  The main arm is slotted to allow the use of pinch bolts and our rotating clamps on our exclusive adjuster lock down camber and track width settings.  Our double adjuster is machined from 4130 chromoly and is electroless nickel plated for corrosion resistance.  

We use billet 2024 aluminum hex we machine and gun drill the trailing arms to reduce weight and utilize our rotating clamp system to easily lock down caster settings.  Blue anodized titanium hardware shaves even more unsprung weight from the arms, without compromising strength.  Anti dive (when installed in the front) and anti squat (when installed in the rear) adjustment is achieved with stainless steel spacers for the forward mounting position of the trailing/caster arm allowing you to raise or lower this pivot point and fine tune the balance of your car.  Roll center correction is achieved with stainless steel spacers that work in conjunction with the heat treated 4340 chromoly ball joint stud allowing you to lower the ball joint location at the knuckle.  Finally, the use of FK rod ends and high misalignment spherical bearings eliminates the flex and binding found in the OEM control arms while allowing smooth articulation.
