{"product_id":"wilwood-powerlite-4-piston-caliper-kit","title":"Wilwood Powerlite 4-Piston Caliper Kit","description":"By replacing stock cast iron calipers with lightweight aluminum Wilwood Powerlite parts, the kit sheds approximately 4 lbs of weight per front wheel. The four-piston caliper design ensures consistent pad pressure and improved braking performance.\n\nThis kit utilizes Wilwood's compact aluminum radial mount Powerlite caliper, which fits around smaller Miata discs while remaining stiff and providing even pressure across its 5 square inch pad. The pistons are sized to maintain the stock pedal feel. It comes with Wilwood BP-20X compound pads, suitable for street and autocross use.\n\nWhile effective for street, autocross, and light track applications with better heat management than stock, these are not intended as heavy-duty track brakes. For more demanding track use, Flyin Miata recommends their four-wheel big brake kit with Dynapro calipers. Compatibility varies with rotor size: the 10-inch rotor setup may require wheel clearance checks, especially with 14-inch factory wheels, while the 11-inch (10.6 inch) rotors should fit most wheels. Rotors must not exceed 22.1 mm in thickness. The hard-anodized finish ensures durability but may result in slight variations in caliper color shade.\n\nIncludes calipers, BP-20X pads, mounting brackets, and stainless steel lines. Rotors are not included. The kit fits 1990-1997 and 2000-2005 Miata models (including MSM trims).","brand":"Flyin Miata","offers":[{"title":"Default Title","offer_id":52688389833016,"sku":"14-16151~10","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662660952.webp?v=1784889439","url":"https:\/\/store.motormia.co\/products\/wilwood-powerlite-4-piston-caliper-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
