The use of PTFE-lined, F1-fit FK USA spherical bushings eliminates OEM rubber bushing deflection and bind, allowing the suspension to freely articulate without undampened rubber \"spring\" forces, while also preventing unwanted geometry changes and vague feedback that occur due to bushing deflection.\u003c\/p\u003e\n\u003c!-- Intro Description --\u003e\n\u003ch3\u003eTechnical\u003c\/h3\u003e\n\u003ch4\u003eZero Bushing Deflection\u003c\/h4\u003e\n\u003cp\u003ePrecision Bump Geometry, Every Corner\u003c\/p\u003e\n\u003cp\u003eCompliant OEM bushings deflect under load to improve NVH and influence the handling behavior at the limit. This elastokinematic tuning has to meet the diverse goals set by the vehicle's design requirements, including NVH, component cost, service life, and more.\u003cbr\u003eOur spherical bushing kit is designed for those who prioritize performance and handling precision. This is achieved by eliminating bushing deflection and the resulting compliance steer effects, which makes driving more predictable, and simplifies the kinematic setup in the rear to make dialing in the car that much easier.\u003c\/p\u003e\n\u003ch4\u003eReduce Wheel Hop\u003c\/h4\u003e\n\u003cp\u003eKeep the Wheel Planted\u003c\/p\u003e\n\u003cp\u003eSudden acceleration from launch control, low gear changes, sharp braking or even ABS engagement can initiate wheel hop in some conditions. The OEM rubber bushings contribute by deflecting under load, which allows the wheel to move and enter into a destructive wheel hop cycle. SPL spherical bushings eliminate the deflection in the rear lower arm and help maintain consistent tire contact.\u003c\/p\u003e\n\u003ch4\u003ePrevent Bumpsteer\u003c\/h4\u003e\n\u003cp\u003ePredictable Handling Characteristics\u003c\/p\u003e\n\u003cp\u003eThe rear lower trailing control arms locate the wheel longitudinally (front to back). Under heavy acceleration loads from engine torque, track curbing, and\/or braking torque, the OEM rubber bushings deflect, causing changes to the kinematics that can result in bumpsteer. Switching to spherical bushings eliminates this deflection, which retains predictable handling characteristics and prevents instability due to bumpsteer.\u003c\/p\u003e\n\u003ch4\u003eEliminates Bushing Bind\u003c\/h4\u003e\n\u003cp\u003eLess Bounce, More Control, Greater Simplicity\u003c\/p\u003e\n\u003cp\u003eBushing bind is a significant source of resistance to suspension travel and acts as a rubber torsion spring that resists compression and rebound. This force is poorly controlled by the damper and complicates the suspension model. PTFE-lined spherical bearings have extremely low friction and allow the spring and damper to work more effectively through the entire sweep of the suspension. This delivers a more linear, controlled, and predictable driving experience.\u003c\/p\u003e\n\u003c!-- Technical Benefits --\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eImproved Handling Precision \u0026amp; Stability\u003c\/li\u003e\n\u003cli\u003eReduced Wheel Hop\u003c\/li\u003e\n\u003cli\u003eNear Zero Sliding Friction\u003c\/li\u003e\n\u003cli\u003eSharpened Rear Suspension Response and Feedback\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- Benefits List --\u003e\n\u003ch3\u003eMaterials\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6061-T6 Billet Aluminum Bushing Shells\u003c\/li\u003e\n\u003cli\u003eFK USA PTFE-lined Spherical Bearings\u003c\/li\u003e\n\u003cli\u003e6061-T6 Aluminum Spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- Materials List --\u003e\n\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/product_images\/uploaded_images\/made-in-usa.png\" style=\"max-width:100%\"\u003e\n\u003c!-- Made In USA --\u003e \u003c!-- \u003cdiv id=\"featured-on\" class=\"featured\"\u003e\n    \u003ch3\u003eFeatured On\u003c\/h3\u003e\n        \u003ch4\u003eEric Sutton's \/ Driver's Source Solo National Champion 996 Turbo\u003c\/h4\u003e\n        \u003cimg class=\"__mce_add_custom__\" title=\"Eric Sutton's 996 Turbo\" src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/eric-sutton-996tt.jpg?t=1707863724\" alt=\"Eric Sutton's 996 Turbo\" width=\"600\" height=\"400\" \/\u003e\n        \u003ch4\u003eChelsea DeNofa's Cayman\u003c\/h4\u003e\n        \u003cimg class=\"__mce_add_custom__\" title=\"Chelsea DeNofa's Cayman\" src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/denofa-cayman.jpg?t=1756158451\" alt=\"DeNofa Cayman\" width=\"600\" height=\"400\" \/\u003e \n\u003c\/div\u003e Featured On --\u003e\n\u003ch3\u003eNoise, Vibration, and Harshness (NVH)\u003c\/h3\u003e\n\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/nvh-rating-6.png?t=1723245776\" style=\"max-width:100%\"\u003e\n\u003cp\u003eReplacing the OEM rear lower trailing control arm bushings with SPL sphericals will add a small to moderate amount of NVH in some driving situations.
