987 RSS Tarmac Front Series 2-Piece Lower Control Arm Kit (2006+)

This is special version of the tarmac series lower control arms that fit only the front of 987 boxster and cayman cars 2006 and later (they will not fit the rear). The normal part #656 tarmac series lower control arms will fit the rear.
 
The RSS Tarmac Series is 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.
 
Features & Benefits:
Completely Serviceable: For the extreme, repetitive track day enthusiast or racer, our high strength steel alloy spherical bearings (with a friction reducing, longevity increasing Teflon liner) can be replaced unlike the motorsports arms, in which case a new set of arms will need to be purchased if the spherical bearings are worn out.
Adjustable Suspension Geometry: Adjust dynamic camber values and roll center heights with our unique zinc plated steel bushings.
Solid Monoball Control Arm Ends: Offers better handling and a more responsive suspension over the factory one-piece rubber injected control arm by eliminating bushing deflection (also uses the same high strength steel alloy spherical bearing found in our control arm monoball kit).
6061 Aerospace Grade Billet Aluminum Construction: Allows for a more uniform molecular structure at every point of the arm over the cast motorsports arm providing a more durable and inherently stronger part. Manufacturing from billet aluminum rather than casting results in fewer impurities in the metal.
Unique Design: Provides more gusseting over the motorsports arms for superior looks, added strength and durability.
Anodized Aluminum Surfaces and Zinc Plated Steel Parts: Allows for better corrosion resistance against the elements.
