{"product_id":"supercomp-8-piston-400mm-x-36mm-big-brake-kit","title":"SuperComp 8-Piston 400mm x 36mm Big Brake Kit","description":"The Ksport SuperComp Big Brake Kit represents a significant upgrade for your BMW E46 330i, delivering ultimate stopping power through advanced brake technology. The SuperComp caliper, forged from aircraft-quality billet aluminum, is extremely lightweight and features a differential bore configuration with larger pistons than Ksport's ProComp calipers. It includes aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates, along with stainless-steel brake lines that prevent expansion under pressure for improved pedal feel and response.\n\nThe kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight while preventing thermal stresses from warping the disc. The unique slot design on the rotor aids in reducing braking noise and expelling gas and pad debris, while cross-drilled rotors are recommended for daily-driven vehicles as they tend to run cooler. Standard equipment includes Ksport SC5 Street Pads, designed for optimal braking performance under street and occasional track use, offering reduced brake dust and noise. Optional RC5 Race Pads are available for extreme track conditions.\n\nThis big brake kit is made to order and non-refundable. The kit is compatible with the BMW E46 3 Series (1999-2006) 330Ci and 330i models equipped with the M54 3.0L engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868430823736,"sku":"BKBM031-961CO","price":4586.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986879.jpg?v=1787914080","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-400mm-x-36mm-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
