{"product_id":"lightweight-aluminum-single-mass-flywheel","title":"Lightweight Aluminum Single-Mass Flywheel","description":"The JB Racing 520-180-240 is a lightweight aluminum flywheel designed to enhance engine performance. This single-mass unit replaces the stock dual-mass flywheel, significantly reducing rotational mass and Moment of Inertia (MOI).\n\nCrafted from billet aluminum, this flywheel weighs only 10 lbs, a substantial decrease from the stock flywheel's 25 lbs. This reduction in mass allows the engine to spin up faster, resulting in quicker acceleration, snappier gear changes, and more effortless rev-matching. The single-mass design also replicates key OEM dimensions, ensuring compatibility with original clutch components.\n\nThis JB Racing flywheel is specifically designed for the BMW E46 M3 S54 3.2L.","brand":"JB Racing","offers":[{"title":"Default Title","offer_id":52688945840440,"sku":"520-180-240","price":602.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663697103.png?v=1784899039","url":"https:\/\/store.motormia.co\/products\/lightweight-aluminum-single-mass-flywheel","provider":"MOTORMIA","version":"1.0","type":"link"}
