Unlike wet-layup or hand-laid alternatives, pre-preg delivers a tighter, more consistent weave, superior strength-to-weight ratio, and a show-finish gloss clear coat with full UV protection. The result is a part that looks as good in five years as it does on day one.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment Notes:\u003c\/strong\u003e Built to suit the \u003cstrong\u003eBMW 4 Series G22 G23\u003c\/strong\u003e, model years \u003cstrong\u003e2020+\u003c\/strong\u003e. This is a direct-fit replacement or overlay depending on variant — the part matches the factory mounting pattern and panel geometry of the listed models, so a standard install is bolt-on \/ clip-on with no cutting or drilling required. If your car was built with a non-standard options pack, it's worth checking fitment with our team before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e Fitment is straightforward for an experienced installer using standard hand tools. We strongly recommend installation by a qualified bodyshop or detailer, particularly for exterior components that require panel alignment, adhesive bonding, or painted-surface preparation. Full fitment guidance is provided in the box, and our support team can help confirm the best approach for your specific car.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe FORM Industries Difference:\u003c\/strong\u003e Where many aftermarket brands compete on price, FORM competes on fit and finish. Every part in the catalogue is developed on real cars — not just in CAD — with panel-gap tolerances, material selection, and finishing processes benchmarked against the OEM part it replaces. It's why FORM has become one of the go-to names for BMW M, Audi RS, and Porsche GT owners looking for an upgrade that genuinely measures up.\u003c\/p\u003e","brand":"FORM Industries","offers":[{"title":"Default Title","offer_id":55620908908884,"sku":"FO-BG22CORDCF","price":1319.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/0425\/3268\/files\/tre-pre-preg-carbon-fibre-competition-rear-diffuser-set-for-bmw-4-series-2020-g22-g23-tre-876176_9e6aa19a-fad4-4cbc-bb2e-be8f775f74d3.jpg?v=1778501850","url":"https:\/\/fifty9performance.co.uk\/products\/bmw-4-series-g22-g23-pre-preg-carbon-fibre-competition-rear-diffuser-set-by-form-2020","provider":"Fifty9 Performance","version":"1.0","type":"link"}
