Whether you are chasing optimal alignment for track use, correcting camber loss after lowering, or dialing in a motorsport suspension setup, the SPL RUA NC arms give you the adjustment authority that the factory eccentric washer system simply cannot provide. Sold as a pair, these are a must-have upgrade for any seriously lowered or performance-oriented NC Miata or RX-8 build.\u003c\/p\u003e\n\n\u003cp\u003eThe factory rear upper lateral arm on the NC Miata and RX-8 uses an eccentric washer for camber adjustment, but the range is too limited to restore proper alignment geometry after significant ride height reduction or to achieve aggressive camber settings for track work. The SPL RUA NC arms eliminate that limitation entirely with a rotating clamp design that provides wide, precise adjustment without requiring you to access hard-to-reach fasteners. SPL also includes stainless steel spacers in the kit to help correct roll center height on lowered vehicles, addressing a secondary geometry problem that most alignment solutions ignore.\u003c\/p\u003e\n\n\u003cp\u003eSPL Parts builds the RUA NC with gun-drilled 2024 aluminum alloy main links, blue anodized titanium hardware, and stainless steel spacers: a combination that reduces unsprung weight without compromising the structural integrity needed for high-load track use. FK Spherical Rod Ends with PTFE-lined Teflon races replace the soft OEM bushings, eliminating bushing deflection under hard cornering, braking, and acceleration. The Teflon liner is chemically bonded to the inner race diameter and operates reliably from -65 to 325 degrees Fahrenheit, making these arms equally at home on a daily driver and a dedicated time-attack car.

Vehicles running wider wheels and tires, aggressive alignment setups, or track duty will also benefit significantly from the increased adjustment range.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy do I need adjustable rear upper camber links on my NC Miata or RX-8?\u003c\/strong\u003e\u003cbr\u003e\nThe factory rear upper arm uses an eccentric washer that provides only limited camber adjustment. Once you lower the car more than a modest amount, that range is no longer sufficient to bring rear camber back into spec. The SPL RUA NC arms provide a much wider adjustment range to correct alignment and allow you to dial in camber for your specific application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the rotating clamp design?\u003c\/strong\u003e\u003cbr\u003e\nThe rotating clamp design means the locking mechanism can be accessed and tightened without requiring the arm to be in a specific position. This makes alignment adjustments faster and easier compared to traditional designs that require repositioning tools around the arm.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo these arms correct roll center?\u003c\/strong\u003e\u003cbr\u003e\nYes. SPL Parts includes stainless steel spacers with the SPL RUA NC kit specifically to correct roll center geometry on lowered vehicles, addressing a common secondary issue that most camber link solutions do not account for.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre FK Spherical Rod Ends louder than OEM rubber bushings on the street?\u003c\/strong\u003e\u003cbr\u003e\nSPL Parts uses 3-piece Teflon-lined FK Heim joints, which are designed for low-friction, quiet operation compared to solid uniball designs. Most street users report acceptable NVH on daily driven cars, though some additional suspension noise relative to rubber bushings is normal with any spherical bearing design.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use these for both street and track?\u003c\/strong\u003e\u003cbr\u003e\nYes. The PTFE liner in the FK Rod Ends operates from -65 to 325 degrees F and is rated for high dynamic loads, making the SPL RUA NC suitable for both street driving and track events including time attack and autocross.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre these sold as a pair?\u003c\/strong\u003e\u003cbr\u003e\nYes. One order of the SPL RUA NC includes both the left and right rear upper lateral arms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre replacement rod ends available?\u003c\/strong\u003e\u003cbr\u003e\nYes. SPL Parts offers replacement rod ends in both right-hand and left-hand thread configurations for future maintenance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre these compatible with the Mazda RX-8 as well as the NC Miata?\u003c\/strong\u003e\u003cbr\u003e\nYes. The SPL RUA NC arms are designed to fit both the 2006-2015 Mazda Miata MX-5 NC and the 2003-2012 Mazda RX-8, which share compatible rear suspension geometry for this application.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003cp\u003eInstallation of the SPL RUA NC Rear Upper Lateral Camber Arms requires removal of the rear wheel and the factory rear upper lateral arm. The SPL arms install in the OEM mounting locations using the included hardware. After installation, the vehicle must be aligned on a four-wheel alignment rack to properly set rear camber. Full installation instructions are available from SPL Parts. Professional installation is recommended to ensure proper alignment settings are achieved.\u003c\/p\u003e","brand":"SPL Parts","offers":[{"title":"Default Title","offer_id":45974137274447,"sku":"SPPSPL RUA NC","price":358.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/spl-parts-rear-upper-camber-links-miata-nc-rx8.png?v=1782654301","url":"https:\/\/www.blackopsautoworks.com\/products\/spl-parts-rua-nc-mazda-miata-nc-rx-8-rear-upper-camber-links","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
