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.


• 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.
