The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub.\u003cbr\u003e","brand":"SPEC","offers":[{"title":"Default Title","offer_id":47852390318338,"sku":"SPECSB354","price":539.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/sxc-sa064_80.jpg?v=1784961142","url":"https:\/\/www.lethalperformance.com\/products\/spec-87-91-bmw-m3-2-3l-stage-4-clutch-kit","provider":"Lethal Performance","version":"1.0","type":"link"}
