{"product_id":"bmw-e8x-e9x-rear-lower-trailing-arms","title":"BMW E8X\/E9X Rear Lower Trailing Arms","description":"\u003cp\u003eThe SPL Rear Lower Trailing Arms for the E8X\/E9X replace the flimsy stamped steel BMW arms to provide improved rigidity in the rear suspension and reduce weight. Technical Improved Rigidity No More Bent OEM Arms Rigidity is a commonly overlooked aspect of suspension components that is critical for delivering the sharp driving experience we all want. Under hard acceleration and braking, the arm will see hundreds of pounds of force that causes the OEM arm to deflect several millimeters, which when combined with the OEM rubber bushing deflection causes instability due to rear bumpsteer. Reduced Weight Improve Suspension Control and Response Weight is critical, it affects every aspect of the vehicle's performance. In the suspension, the control arms contribute to the total unsprung mass, which is weight that is more difficult to control, particularly over bumps. More unsprung mass leads to more wheel hop, less stability over rough roads, and a greater need for compression dampening to manage it. Even a couple of pounds can be significant when you consider that bumps will impart anywhere from 3 to 30Gs of acceleration. Benefits Improved Suspension Rigidity Reduced Unsprung Mass Lightweight: 0.75 lbs (0.34 kg) per Side - 35% Lighter than OEM Materials 6061-T6 Billet Aluminum Arms (Anodized Black) Zinc Plated Class 10.9 Metric Hardware Noise, Vibration, and Harshness (NVH) The arms have no impact on NVH.
