The SPL RTA 981 eliminates OEM rubber bushing deflection and provides a wide range of toe and bump steer adjustment that the factory links simply cannot offer. Gun-drilled from 2024-T351 anodized aluminum with Teflon-lined FK Heim joints and SPL's signature rotating clamp design, these arms are engineered for high performance street use and motorsport competition alike.\u003c\/p\u003e\n\u003cp\u003eSold as a pair. Made in the USA.\u003c\/p\u003e\n\u003ch4\u003eWhy the SPL RTA 981 Outperforms Factory Toe Links\u003c\/h4\u003e\n\u003cp\u003eThe factory rear toe links on the 981 and 982 Porsche platform use rubber bushings at the pivot points. Under lateral load, those rubber bushings compress, deflect, and flex introducing inconsistent toe changes that the driver never asked for. Every time the car corners hard, the rear suspension geometry shifts slightly away from where you set it. The result is reduced response, inconsistent turn-in feel, and a rear end that moves around when it should be planted.\u003c\/p\u003e\n\u003cp\u003eWhen a 981 or 718 is lowered, the problem compounds. The factory links are not designed to operate at reduced ride heights and introduce excess toe-in that falls outside the factory alignment adjustment range. You end up with rear toe you cannot dial out, rapid inner tire wear, and a car that pushes into understeer when it should rotate cleanly.\u003c\/p\u003e\n\u003cp\u003eThe SPL RTA 981 solves both problems. The rubber bushings are replaced entirely with Teflon-lined FK Heim joints that rotate freely in all directions without deflection or bind. Adjustment is built into the arm design, giving a wide range of toe correction that covers both factory-height and lowered applications.\u003c\/p\u003e\n\u003ch4\u003eConstruction and Materials\u003c\/h4\u003e\n\u003cp\u003eEvery SPL RTA 981 arm starts as a 2024-T351 aluminum billet. The main link is gun-drilled to reduce weight without sacrificing structural rigidity. The aluminum is black anodized for corrosion resistance and appearance. SPL's engineering team uses Computer Aided Design and Finite Element Analysis on every component to verify strength margins under real-world suspension loads before any part goes into production.\u003c\/p\u003e\n\u003cp\u003eThe rod ends are high misalignment, low friction, 3-piece Teflon-lined FK Heim joints. The Teflon liner eliminates metal-on-metal contact at the pivot point, reduces friction across the full range of angular motion, and extends service life compared to non-lined rod ends. The 360-degree rotation of the Heim joint allows the arm to move freely through the full suspension travel without binding at any point in the travel.\u003c\/p\u003e\n\u003cp\u003eSPL's rotating clamp design replaces the traditional jam nut locking method. Standard adjustment arms require you to hold the rod end in position while simultaneously tightening a jam nut which inevitably rotates the rod end slightly as you tighten, throwing off your adjustment. SPL's clamp locks the rod end in place independently, so the adjustment you set is exactly the adjustment that gets locked in. No jam nut rotation error, no re-checking after torquing.\u003c\/p\u003e\n\u003ch4\u003eFitment for Porsche 981 and 982 Chassis\u003c\/h4\u003e\n\u003cp\u003eThe SPL RTA 981 fits all variants of the \u003cstrong\u003e2013-2016 Porsche 981 Boxster and Cayman\u003c\/strong\u003e and all variants of the \u003cstrong\u003e2017 and newer Porsche 718 Boxster and 718 Cayman (982 chassis)\u003c\/strong\u003e.

The rotating clamp locking system and gun-drilled aluminum construction are signature SPL engineering features found across their entire suspension lineup.\u003c\/p\u003e\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the SPL RTA 981 fit the 2013-2016 Porsche 981 Boxster and Cayman?\u003c\/strong\u003e\u003cbr\u003eYes. The SPL RTA 981 is a confirmed direct fit for all variants of the 2013-2016 Porsche 981 Boxster and Cayman. No trim exclusions apply within the 981 chassis family.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the SPL RTA 981 fit the Porsche 718 Boxster and Cayman?\u003c\/strong\u003e\u003cbr\u003eYes. The SPL RTA 981 fits all 2017 and newer Porsche 718 Boxster and 718 Cayman models on the 982 chassis. SPL lists fitment as open-ended for the 718 generation, covering all trims and variants through current production.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the SPL RTA 981 fit a lowered 981 or 718?\u003c\/strong\u003e\u003cbr\u003eYes, and this is specifically one of the primary use cases for these arms. When a 981 or 718 is lowered, the factory toe links create excess toe-in that falls outside the OEM alignment adjustment range. The SPL RTA 981 provides the adjustment range needed to restore proper rear toe geometry at lowered ride heights.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the advantage of Heim joints over rubber bushings in the SPL RTA 981?\u003c\/strong\u003e\u003cbr\u003eRubber bushings deflect and compress under lateral suspension loads, creating inconsistent and unpredictable toe changes during cornering. FK Teflon-lined Heim joints have no deflection and rotate freely through the full range of suspension travel. The result is a rear suspension that responds exactly where it is set and stays there through hard cornering, braking, and acceleration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is SPL's rotating clamp design and why does it matter?\u003c\/strong\u003e\u003cbr\u003eTraditional adjustable arms use a jam nut to lock the rod end after adjustment. The problem is that tightening the jam nut rotates the rod end slightly, shifting your alignment setting as you lock it in. SPL's rotating clamp locks the rod end independently of the jam nut tightening process, so the adjustment you dial in is the adjustment that stays locked. This is especially important when chasing precise alignment targets on a track setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the SPL RTA 981 fit the Porsche 718 GT4 or Cayman GT4 RS?\u003c\/strong\u003e\u003cbr\u003eSPL lists the RTA 981 for all 718 Cayman and Boxster variants on the 982 chassis without specific trim exclusions. The 718 GT4 and GT4 RS use the same 982 chassis. Verify your chassis code before ordering and contact SPL Parts directly at splparts.com if you have questions about a specific variant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the SPL RTA 981 require an alignment after installation?\u003c\/strong\u003e\u003cbr\u003eYes. Any time rear toe arms are replaced or adjusted, a full four-wheel alignment is required. These arms are designed to be set to a specific toe value during alignment. Always have the car aligned on a proper alignment rack after installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the SPL RTA 981 suitable for track and autocross use?\u003c\/strong\u003e\u003cbr\u003eYes. SPL rates the RTA 981 for high performance street and race applications. The aluminum construction, Heim joints, and rotating clamp design are all features that perform in demanding track environments. The arms are used in time attack, HPDE, and wheel-to-wheel racing on the 981 and 718 platform.\u003c\/p\u003e","brand":"SPL Parts","offers":[{"title":"Default Title","offer_id":45939296698447,"sku":"SPPSPL RTA 981","price":718.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/spl-rear-toe-arms-2013-2016-porsche-boxster-cayman.png?v=1781905923","url":"https:\/\/www.blackopsautoworks.com\/products\/spl-rta-981-rear-toe-arms-porsche-981-982-718-boxster-cayman","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
