SPL's front upper arms provide a wide range of camber adjustment for the front of your 350Z and G35. Designed using CAD and FEA, the new version 2 arms is completely re-designed to be stiffer than the original version 1 arms under braking and acceleration for even better performance. CNC machined from billet T6061 aluminum, and featuring QA1 Endura 2000 series spherical bearings with maintenance-free injection molded teflon/kevlar lining, SPL's new arms are lightweight and give quiet operation and long life between service.
Camber is adjusted using shims, which simplifies camber adjustment and reduces installation errors. Camber adjustment range is -2.5deg to +1deg relative to stock arm; most cars will see actual on-car camber adjustment range of -4deg to -0.5deg, depending on ride height. Off-car adjustment of +/- 1 deg of caster can be set independently of camber.
