The result is a range of parts that install like factory equipment and hold up the way factory equipment should.\u003c\/p\u003e","brand":"FORM Industries","offers":[{"title":"Default Title","offer_id":55620907041108,"sku":"FO-BG80RDPECF","price":649.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/0425\/3268\/files\/bmw-g80-g81-m3-g82-g83-m4-pre-preg-carbon-fibre-oem-style-rear-diffuser-by-tre-2021-tre-574842_68a032c3-c034-4646-b495-967c2ff462be.jpg?v=1778501795","url":"https:\/\/fifty9performance.co.uk\/products\/bmw-g80-g81-m3-and-g82-g83-m4-pre-preg-carbon-fibre-rear-diffuser-by-form-2021","provider":"Fifty9 Performance","version":"1.0","type":"link"}
