{"product_id":"single-mass-billet-aluminum-flywheel","title":"Single-Mass Billet Aluminum Flywheel","description":"The JB Racing Aluminum Lightweight Flywheel is engineered to significantly reduce the high rotating mass found in stock E30 325i flywheels, particularly those from 12\/86 onwards. This reduction in static weight and Moment of Inertia (MOI) allows the engine to rev more quickly, facilitates faster shifting, and makes rev-matching considerably easier.\n\nJB Racing flywheels are CNC machined, zero-balanced to eliminate vibration, and feature a replaceable hardened steel clutch surface that is bolted on, not riveted. Standard inclusions comprise a factory starter ring gear, heli-coil inserts for the pressure plate to prevent stripping during clutch replacement, a hardened steel gaul plate, captive design 10mm dowel pins, all metric pressure plate hardware, and flywheel, pressure plate, and dowel pin bolts. The new weight is 8 pounds compared to the stock 16 pounds.\n\nThis flywheel is specifically designed for E30 325i models from 12\/86+ and E30 325ix models from 8\/87+. We recommend using a sprung-hub clutch disc with this lightweight flywheel to minimize noise and drivetrain stress.","brand":"Rogue Engineering","offers":[{"title":"Default Title","offer_id":52663525572920,"sku":"520-060-228","price":581.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687614195.png?v=1784327718","url":"https:\/\/store.motormia.co\/products\/single-mass-billet-aluminum-flywheel","provider":"MOTORMIA","version":"1.0","type":"link"}
