P2M Nissan 350Z / Infiniti G35 rear traction trailing rod is constructed from high strength S45C alloy steel for durability. Combo with the rear camber and spring bucket delete arm, one can dial in full suspension alignment geometry for your intended vehicle use. Must of the adjustment on the Z33 comes from the rear toe/camber arms along with going with full coilover rear setup. By retaining the stock rear spring arm setup, not much adjustment is recommended to be done on this part. Even then by replacing this arm with the 3pc teflon lined pillow ball can still improve the handling characteristics of the vehicle.
