The unique shape of the high surface area body creates a caliper with superior brake fluid cooling and allows more airflow through the rotor. Optimized profile high-temperature seals provide better piston retraction resulting in less drag. The unique center X-bridge strengthens the caliper body without adding mass or obstructing airflow to the brake rotor or pads. Computer FEA design and precision CNC machining of the stress-flow forged aluminum body results in a caliper weighing just 4.66 pounds - 1\/2 pound less than a comparable sized Wilwood Superlite caliper.","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":47872237076738,"sku":"WIL120-16467","price":879.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/544d99acfdaac1216ae2133b12fae9dc_b50b4e54-f33d-4ef8-94a4-64a2dc5dc23f.jpg?v=1786047220","url":"https:\/\/www.lethalperformance.com\/products\/wilwood-caliper-type-iii-ano-l-r-xrz4r-1-38in-1-38in-piston-810in-disc","provider":"Lethal Performance","version":"1.0","type":"link"}
