Larger PTFE-lined, F1-fit FK USA spherical bushings provide the benefits of the OEM spherical with longer life due to the increased surface area of the bearing. The kit allows for a deeper customization of the suspension geometry to better suit your driving preferences and adapt to changes in tracks, aero loading, tires, and more.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"technical-benefits\" class=\"technical-benefits-list\"\u003e\n\u003ch3\u003eTechnical\u003c\/h3\u003e\n\u003ch4\u003eAnti-Geometry Adjustment\u003c\/h4\u003e\n\u003cp class=\"tech-sub-text\"\u003eFine Tune the Chassis Response Under Hard Braking or Acceleration\u003c\/p\u003e\n\u003cp\u003eThe provided spacers allow for fine tuning of the anti-squat geometry. The more anti-squat (expressed as a %) a car has the less the rear suspension will squat under acceleration. This geometry's effect is more pronounced in lower gears and higher rates of acceleration. Additional anti-squat can prevent bumpsteer on corner exit and improve corner exit acceleration as well as peak tire grip available under hard acceleration. Certain road surfaces and setups may benefit from running slightly less anti-squat, so we've left it adjustable in small increments.\u003c\/p\u003e\n\u003ch4\u003eRear Kinematic Adjustments\u003c\/h4\u003e\n\u003cp class=\"tech-sub-text\"\u003eSet the Fine Details on Rear Suspension Behavior\u003c\/p\u003e\n\u003cp\u003eAdjusting the rear camber via the lower control arm also changes the angle of the rear traction arm, causing the kinematics to change. The SPL arms allow you to properly shorten or elongate the traction arm to bring the kinematics back inline with OEM behavior, or make adjustments to promote additional stability or rotation depending on your preferred dynamics behavior. This can be especially useful for eliminating unwanted tire scrub and negative dynamic behaviors with the use of substantial aerodynamic load, meaning you'll gain more speed on the longer straights and have less tire heating due to aero induced bumpsteer.\u003c\/p\u003e\n\u003ch4\u003eRear Wheel Location Adaptability\u003c\/h4\u003e\n\u003cp class=\"tech-sub-text\"\u003eMove the Location of the Rear Wheel\u003c\/p\u003e\n\u003cp\u003eFor setups that are prioritizing rear tire size, the adjustable rear traction arm allows for the wheel to be moved longitudinally to improve clearance between the body and tire.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"benefits-list\"\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable Anti-Squat and Rear Kinematics\u003c\/li\u003e\n\u003cli\u003eLightweight: 2.08 lbs (0.94 kg) per Side (14% Lighter than OEM)\u003c\/li\u003e\n\u003cli\u003eImproved Rear Grip\u003c\/li\u003e\n\u003cli\u003eGreater Adaptability for Wheel\/Tire Clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"materials-list\"\u003e\n\u003ch3\u003eMaterials\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6061-T6 Billet Aluminum Arms, 360° Clamps, and Clevis (Anodized Black)\u003c\/li\u003e\n\u003cli\u003e6061-T6 Billet, Hollow Aluminum Trailing Link (Anodized Black)\u003c\/li\u003e\n\u003cli\u003e4140 ChroMoly Clevis Stud\u003c\/li\u003e\n\u003cli\u003e6061-T6 Aluminum Adjustment Spacers\u003c\/li\u003e\n\u003cli\u003eZinc Plated Class 10.9 Metric Hardware\u003c\/li\u003e\n\u003cli\u003eTi-6Al-4V Titanium 1\/4\"-20 Socket Head Allen Screws (Anodized Blue)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"made-in-usa\" class=\"usa\"\u003e\u003cimg class=\"__mce_add_custom__\" title=\"made-in-usa.png\" src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/product_images\/uploaded_images\/made-in-usa.png\" alt=\"made-in-usa.png\" width=\"319\" height=\"30\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"NVH-rating\"\u003e\n\u003ch3\u003eNoise, Vibration, and Harshness (NVH)\u003c\/h3\u003e\n\u003cimg class=\"NVH-image\" src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/nvh-rating-0.png?t=1723245776\" alt=\"Product NVH Rating\"\u003e\n\u003cp\u003eThe OEM arms have spherical bearings so there isn't a pronounced difference in NVH.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"fitment-list\" class=\"fitment-list\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003e2013 - 2016 Porsche Boxster, Boxster S, Boxster GTS (981)\u003c\/p\u003e\n\u003cp\u003e2013 - 2016 Porsche Cayman, Cayman S, Cayman GTS (981)\u003c\/p\u003e\n\u003cp\u003e2015 - 2016 Porsche Cayman GT4 (981)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"alt\" class=\"product-warning-box\"\u003e\n\u003cp id=\"pwb-title\"\u003eADDITIONAL FITMENT INFO\u003c\/p\u003e\n\u003cdiv class=\"warning-text\"\u003e\n\u003ch4\u003eWILL THIS FIT A ...\u003c\/h4\u003e\n\u003cp\u003eWe limit the above applications to known fitments from testing and research.
