Skunk2's Hard Anodized Rear Lower Control Arms for the '02-'06 RSX and 03-08 Element are based off of the same technology the company's been using on its own race cars for more than a decade and are a must-have for enthusiasts looking to fine-tune their suspension for maximum handling performance. Skunk2's Rear Lower Control Arms are direct replacements, maintain OEM suspension geometry, and are ideal for street and race applications. Each arm is forged from aircraft-quality 2024 billet aluminum, precision CNC-machined, and is more than 25 percent lighter than the OEM arms. Skunk2 Rear Lower Control Arms also feature adjustable anti-sway bar mounting holes for advanced suspension tuning and optimum balance. The low-deflection, polyurethane bushings act as bearings for quicker response and a more positive feel. Skunk2 also eliminated tearing and un-seating problems typically associated with other fixed rubber bushings by allowing the arm to rotate freely about the bushings. Properly designed suspension components must be strong and functional first and aesthetically pleasing second. Skunk2's Rear Lower Control Arms are both. Each arm's I-beam shape and tapered design is a direct result of efforts to eliminate twisting, bending, and stress risers. Extensive FEA (finite element analysis) testing determined that conventional 'straight and flat' designs are plagued by internal stress risers. A poorly designed arm will concentrate stress in particular zones, causing the arm to fracture and ultimately fail. For maximum suspension performance, Skunk2 Rear Lower Control Arms are best complemented with Skunk2 Rear Camber Kits, Lower Arm Bars, and Strut Tower Bars.
