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 camber loss, bumpsteer, and vague feedback that occur due to bushing deflection.\u003c\/p\u003e\n\u003c!-- Intro Description --\u003e\n\u003ch3\u003eKit Contents\u003c\/h3\u003e\n\u003cp\u003eThe SPL RAB 991 GT3 (Rear Control Arm Bushing Kit) includes:\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003cth\u003ePart Description\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRUAB 991 GT3\u003c\/td\u003e\n\u003ctd\u003eRear Upper Control Arm Spherical Bushings\u003c\/td\u003e\n\u003ctd\u003e1 Kit (4 Bushings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRUTB 991 GT3\u003c\/td\u003e\n\u003ctd\u003eRear Upper Trailing Arm Spherical Bushings\u003c\/td\u003e\n\u003ctd\u003e1 Kit (4 Bushings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRLLB 991 GT3\u003c\/td\u003e\n\u003ctd\u003eRear Lower Control Arm Spherical Bushings\u003c\/td\u003e\n\u003ctd\u003e1 Kit (4 Bushings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRTRB 991 GT3\u003c\/td\u003e\n\u003ctd\u003eRear Lower Trailing Arm Spherical Bushings\u003c\/td\u003e\n\u003ctd\u003e1 Kit (4 Bushings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c!-- Kit Item List --\u003e\n\u003ch3\u003eTechnical\u003c\/h3\u003e\n\u003ch4\u003eImproved Throttle Response and Braking Feel\u003c\/h4\u003e\n\u003cp\u003eDirect Feedback, Instant Response\u003c\/p\u003e\n\u003cp\u003eReplacing the compliant OEM bushings on the two trailing arms (upper \/ lower) with spherical bushings eliminates the slack in the accel \/ braking axis. This means the acceleration and braking forces no longer have to compress or decompress the bushings, they're immediately transmitted into action and without any change in toe due to bushing deflection.\u003c\/p\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\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\u003c\/li\u003e\n\u003cli\u003eEliminates Compliance Steer\u003c\/li\u003e\n\u003cli\u003eNear Zero Sliding Friction\u003c\/li\u003e\n\u003cli\u003eSharpened Rear Suspension Response and Feedback\u003c\/li\u003e\n\u003cli\u003eImproved Braking Stability\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 all of the OEM bushings with sphericals will moderately increase NVH, particularly tire noise and tramlining due to the reduction in compliance.
