RSS / Road Sport SupplyTarmac Series Rear Lower Control Arm Kit (pair)

RSS Tarmac Rear Series Motorsport Lower Control Arms are specifically engineered for use on lowered vehicles that have reduced travel struts/dampers. The RSS Tarmac Series – Motorsports Control Arms are designed for the Porsche driver who demands the absolute maximum in precision handling, feedback and control from their chassis. This system has been specially engineered to provide unmatched performance, quality, strength and serviceability. RSS Tarmac Series Control Arms address the performance related shortcomings of the OEM rubber mounted suspension components which were designed to reduce road noise and vibration for everyday street use. The use of rubber injected moldings in mounting components such as the control arms, thrust arms, upper links and toe arms is a compromise in regards to maximum suspension performance. The soft rubber deflects under suspension load which in turn causes unwanted movement (deflection) between the suspension and chassis. Data also shows that temporary changes in spring rates can occur as well. These movements and changes result in unnecessary corrections and inputs from the driver.

RSS High Performance Tarmac Series Suspension Components are designed, engineered and manufactured on location here in the USA. RSS Tarmac Series Control Arms are manufactured from 6061 aerospace grade billet aluminum. This allows for a more uniform molecular structure at every point of the arm over the cast motorsports arm giving the customer a more durable and inherently stronger part. Manufacturing from billet aluminum rather than casting results in less impurities in the metal. Completely serviceable – for the extreme, repetitive track-day participant, our high-strength steel alloy spherical bearings (with a friction reducing / longevity increasing Teflon liner) can be replaced unlike the motorsports arm, in which case the customer will have to buy a new set of arms if the spherical bearings are worn. Additionally, anodized surfaces and zinc-plated steel parts allow for better corrosion resistance against the elements. Adjustable suspension geometry – adjust dynamic camber values and roll center heights with our unique zinc-plated steel bushings. Solid monoball control arm ends offer a more responsive suspension over the factory one-piece rubber-injected control arm (also uses the same high strength steel alloy spherical bearing found in our control arm monoball kit). Unique design provides more gusseting over the motorsports arms for added strength and aesthetically appealing looks.
