{"product_id":"roll-center-ball-joint-kit","title":"Roll Center Ball Joint Kit","description":"This is ideal for racing classes that do not permit aftermarket control arms. Should you choose to upgrade to SLR tubular arms later, you can retain these spherical-jointed OEM arms.\n\nThe kit replaces your original outer balljoint with a teflon-lined spherical bearing and incorporates the SLR steering plate. This setup corrects the roll center by 35mm, adjusts the bump-steer accordingly, and allows for fine-tuning of both. It also quickens the steering ratio by approximately 40%, reducing the need for custom quick-steer racks. The adjustable Ackerman system enables configuration for race, autocross, or drift use.\n\nFitment is determined by the steering knuckle used; for instance, if using E36 knuckles on an E30, the E36 kit is required. The kit is pre-configured for race or drift use out-of-the-box, with adjustments possible after installation. Lollipop selection depends on the control arm: factory E30\/E36 and SLR Chromoly control arms use a round insert, while factory E46 arms use a hex insert. Note that standard Delrin Lollipop bushings may not work with factory E46 control arms without modification. Installation instructions for control arm ball-joint removal and bearing installation are included. This kit is manufactured and assembled in the USA.","brand":"SLR Speed","offers":[{"title":"Default Title","offer_id":52663690461496,"sku":"C.00.E30.0033","price":766.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687139924.webp?v=1784329022","url":"https:\/\/store.motormia.co\/products\/roll-center-ball-joint-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
