Under hard acceleration and braking, the arm will see hundreds of pounds of force that causes the OEM arm to deflect several millimeters, which when combined with the OEM rubber bushing deflection causes instability due to rear bumpsteer.\u003c\/p\u003e\n\u003ch4\u003eReduced Weight\u003c\/h4\u003e\n\u003cp class=\"tech-sub-text\"\u003eImprove Suspension Control and Response\u003c\/p\u003e\n\u003cp\u003eWeight is critical, it affects every aspect of the vehicle's performance. In the suspension, the control arms contribute to the total unsprung mass, which is weight that is more difficult to control, particularly over bumps. More unsprung mass leads to more wheel hop, less stability over rough roads, and a greater need for compression dampening to manage it. Even a couple of pounds can be significant when you consider that bumps will impart anywhere from 3 to 30Gs of acceleration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"benefits-list\"\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eImproved Suspension Rigidity\u003c\/li\u003e\n\u003cli\u003eReduced Unsprung Mass\u003c\/li\u003e\n\u003cli\u003eLightweight: 0.75 lbs (0.34 kg) per Side - 35% Lighter than OEM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"materials-list\"\u003e\n\u003ch3\u003eMaterials\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e6061-T6 Billet Aluminum Arms (Anodized Black)\u003c\/li\u003e\n\u003cli\u003eZinc Plated Class 10.9 Metric Hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"made-in-usa\" class=\"usa\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv id=\"NVH-rating\"\u003e\n\u003ch3\u003eNoise, Vibration, and Harshness (NVH)\u003c\/h3\u003e\n\u003cimg class=\"NVH-image\" src=\"https:\/\/cdn11.bigcommerce.com\/s-xn4bghc5\/images\/stencil\/original\/image-manager\/nvh-rating-0.png?t=1723245776\" alt=\"Product NVH Rating\"\u003e\n\u003cp\u003eThe arms have no impact on NVH.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eOE Part#\u003c\/p\u003e\n\u003cp\u003e33-32-2-406-291 \/ 33 32 2 406 291 \/ 33322406291\u003c\/p\u003e\n\u003cp\u003e33-32-6-763-477 \/ 33 32 6 763 477 \/ 33326763477\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eMFP# \u003cspan\u003eSPL RTR E9X\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"SPL","offers":[{"title":"Default Title","offer_id":50664331804865,"sku":"SPL-RTR-E9X","price":332.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/SPL-RTR-E9X-L1-0-Rear-Traction-Arm-HiRes__88533.webp?v=1790697647","url":"https:\/\/www.urotuning.com\/products\/spl-parts-rear-lower-trailing-arms-anodized-black-bmw-e8x-e9x-spl-rtr-e9x","provider":"UroTuning","version":"1.0","type":"link"}
