{"product_id":"track-performance-rear-big-brake-kit","title":"Track Performance Rear Big Brake Kit","description":"The Paragon Track Performance Big Brake Kit is engineered to significantly enhance braking performance for track day enthusiasts using the 2007+ Subaru WRX (GR\/GV\/VA) and 2007+ Subaru WRX STI (GR\/GV\/VA) rear applications.\n\nThe kit includes Paragon PA025 4-piston calipers CNC machined from billet 6061-T6 aluminum, offering outstanding rigidity for a consistent pedal feel and improved responsiveness. The calipers feature titanium nitride (TiN) coated pistons that enhance durability and service intervals, along with stainless steel pistons that act as a thermal barrier to prevent brake fluid boiling. High-temperature piston seals and internal dust seals are employed to withstand extreme heat and extend caliper life. The calipers are finished with a hard anodizing for superior wear resistance and will not deteriorate under extreme heat.\n\nThe fully floating 2-piece rotors are constructed from CM-250 special formulated high carbon alloy cast iron and measure 355x32mm. The rotor hats are CNC machined from 6061-T6 aerospace grade aluminum with a Type III Mil-spec hard anodized finish for increased resistance to wear, corrosion, and discoloration.\n\nThis kit includes Paragon P3 “Street\/Track” semi-metallic brake pads, manufactured by Winmax Japan, offering superior stopping power, modulation, and high fade resistance. It also comes with caliper mounting brackets, all necessary hardware, Goodridge DOT approved stainless steel braided brake lines, and caliper anti-rattle clips, providing a complete pre-assembled axle set. The system retains OEM E-brake function.\n\nImportant considerations for installation include verifying wheel fitment. The 355mm brake kits generally require 18\" or larger wheels. All Paragon big brake kits are custom made\/packaged to order, and cannot be returned due to wheel fitment issues. Users must verify fitment using the provided wheel fitment template.","brand":"Alcon","offers":[{"title":"Default Title","offer_id":52686879359288,"sku":"PBK.04.170.355.320.TL.01.02.P3.R","price":2700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660181461.webp?v=1784877943","url":"https:\/\/store.motormia.co\/products\/track-performance-rear-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
