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.\u003cbr\u003eThe kit enables adjustable track width, camber, rear roll center, and anti-squat for a deeper customization of the rear suspension geometry to better suit your driving preferences and adapt to changes in tracks, aero loading, tires, and more.\u003c\/p\u003e\n\u003c!-- Intro Description --\u003e\n\u003ch3\u003eKit Contents\u003c\/h3\u003e\n\u003cp\u003eThe SPL RLCAK 982 (Rear Lower Control Arm Kit) is a complete front or rear kit which 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\u003eRLCA 987 V2\u003c\/td\u003e\n\u003ctd\u003eAdjustable Rear Lower Control Arms\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRTR 982\u003c\/td\u003e\n\u003ctd\u003eAdjustable Trailing Arms\u003c\/td\u003e\n\u003ctd\u003e1\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\u003eCamber Adjustment\u003c\/h4\u003e\n\u003cp\u003eIncrease Camber for More Peak Lateral Grip\u003c\/p\u003e\n\u003cp\u003eOne of the biggest improvements to rear cornering grip you can make is adding more negative camber. This also will significantly improve track event tire life by reducing heavy wear on the outer portion of the tread that occurs when there's insufficient camber angle relative to body roll.\u003cbr\u003eElongating the lower arm will add more camber without the need for adjustable camber plates or eccentric bolts that could potentially slip. However, pairing the SPL LCAs with camber plates allows you more adjustability options for inner and outer tire clearance as well as elongating the track width while retaining a specific camber angle.\u003c\/p\u003e\n\u003ch4\u003eTrack Width Adjustment\u003c\/h4\u003e\n\u003cp\u003eGet More from the Inner Tire\u003c\/p\u003e\n\u003cp\u003eExtending the rear track width promotes a more stable handling behavior and reduces the overall amount of weight that shifts off the inner tire and onto the heavily loaded outer. The SPL rear lower control arm (included), SPL trailing arm(included), and an adjustable camber plate allow you to properly adjust rear track width and set your ideal camber angle.\u003c\/p\u003e\n\u003ch4\u003eRear Roll Center Adjustment\u003c\/h4\u003e\n\u003cp\u003eReduce Body Roll with Geometry not Spring Rate\u003c\/p\u003e\n\u003cp\u003eRoll center is the imaginary point that the chassis rolls about during cornering. The distance between the roll center and the center of gravity (front-view, vertical) is essentially the amount of leverage the chassis has to produce roll. \u003cbr\u003eWhen you lower your Porsche the roll center drops further than the center of gravity, resulting in a larger roll moment (force). Using the roll center correction spacers to correct the angle of the rear lower control arm brings the roll center back up, resulting in less body roll at the same spring rate and less tendency to oversteer with fast transitions.\u003cbr\u003eWith the front and rear SPL kits, you can adjust the pitch of the roll axis which can have a significant effect on the car's handling behavior with respect to over and understeer, especially through esses.\u003c\/p\u003e\n\u003ch4\u003eAnti-Squat Adjustment\u003c\/h4\u003e\n\u003cp\u003eFine Tune the Chassis Response Under Hard Acceleration\u003c\/p\u003e\n\u003cp\u003ePut simply, anti-squat geometry is similar to roll center, but viewed from the side rather than the front. The more anti-squat (expressed as a %) a car has the less the rear suspension will compress under acceleration.\u003cbr\u003eAnti-squat's effect will improve traction in most cases and prevent additional bumpsteer under acceleration. This can also have a stabilizing effect through rolling esses where you utilize throttle to rotate the car.\u003c\/p\u003e\n\u003c!-- Technical Benefits --\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable Rear Camber, Roll Center, Anti-Squat, and Track Width\u003c\/li\u003e\n\u003cli\u003eLightweight: 4.51 lbs (2.05 kg) per Side (8% Lighter than Stock)\u003c\/li\u003e\n\u003cli\u003eImproved Rear Grip and Tire Wear on Track\u003c\/li\u003e\n\u003cli\u003ePrecise Rotation and Steering Feel from Eliminating Bushing Deflection\u003c\/li\u003e\n\u003cli\u003eSharper Throttle Response\u003c\/li\u003e\n\u003cli\u003eImproved Braking Stability\u003c\/li\u003e\n\u003cli\u003eGreater Adaptability for Wheel\/Tire Clearance\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 Arms and Clevis (Anodized Black)\u003c\/li\u003e\n\u003cli\u003e6061-T6 Billet, Hollow Aluminum Trailing Link (Anodized Black)\u003c\/li\u003e\n\u003cli\u003e6061-T6 Aluminum Spacers and 360° Clamps\u003c\/li\u003e\n\u003cli\u003e4140 Chromoly Steel Double Adjuster (Electroless Nickel Plated)\u003c\/li\u003e\n\u003cli\u003e4340 Chromoly Steel Studs (Heat-treated)\u003c\/li\u003e\n\u003cli\u003eClass 10.9 Metric Hardware \/ SAE Grade 8 Imperial 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!-- 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\n\u003ch3\u003eFeatured On\u003c\/h3\u003e\n\u003c!-- \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 --\u003e\n\u003ch4\u003eChelsea DeNofa's Cayman\u003c\/h4\u003e\n\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/denofa-cayman.jpg?t=1756158451\" style=\"max-width:100%\"\u003e\n\u003cbr\u003e\u003c!-- 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\u003eThe rear lower control arms are an important part of mitigating NVH. By eliminating all bushing deflection the rear suspension will transmit more road noise, felt energy from bumps, and can increase tramlining in some cases. However, the reduction of bushing bind and reduced friction will improve ride quality over smoother roads and allow the shock to work more effectively over moderate bumps.\u003cbr\u003eTire choice, tire pressure, spring rates, and shock quality will have significant influence on ride quality as well. For daily driving, felt energy and noise can be reduced moderately by running a more compliant tire, either through reduced pressure (suitable for the load and tire) and\/or taller or softer sidewalls, as well as optimized compression dampening on a quality shock.\u003cbr\u003eMost drivers will find the NVH to be present and tolerable, similar to an OEM GT3 or GT4.\u003c\/p\u003e\n\u003c!-- NVH Rating --\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003e2017+ Porsche Boxster, Boxster S, Boxster GTS - Rear (718 \/ 982)\u003c\/p\u003e\n\u003cp\u003e2017+ Porsche Cayman, Cayman T, Cayman S, Cayman GTS - Rear (718 \/ 982)\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003eCayman GT4 uses a Different Kit: RLCAK 982 GT4 (Coming Soon)\u003c\/p\u003e\n\u003c!-- Fitment List --\u003e\n\u003cp\u003eADDITIONAL FITMENT INFO\u003c\/p\u003e\n\u003ch4\u003eWILL THIS FIT A ...\u003c\/h4\u003e\n\u003cp\u003eWe limit the above applications to known fitments from testing and research.
