Precision machined from billet 6061-T6 aluminium, it also adds chassis stiffness for improved dynamic performance, with no modifications required for installation.\u003c\/p\u003e\n\u003cp\u003eThe MMX Underbody Chassis Brace has been developed specifically for the BMW G8x M3 and M4 platform, providing an additional 15mm of exhaust clearance over the factory brace. This increased clearance helps accommodate larger diameter aftermarket exhaust systems, reducing the risk of contact whilst maintaining the original ground clearance. Beyond providing additional clearance, the MMX Underbody Chassis Brace also contributes to increased chassis rigidity, helping to improve overall dynamic performance. By reinforcing a key structural area beneath the vehicle, the brace aids stability and responsiveness, making it a worthwhile upgrade whether on the road or track. Precision CNC machined from billet 6061-T6 aluminium, the brace combines exceptional strength with low weight. Its carefully optimised profile removes a considerable amount of unnecessary material whilst retaining the rigidity required for demanding use, delivering the premium finish and engineering expected from every MMX product.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eVehicle fitment\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e G-Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis code:\u003c\/strong\u003e G80, G81, G82 \u0026amp; G83\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine code:\u003c\/strong\u003e S58\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel variant:\u003c\/strong\u003e M3 \u0026amp; M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel year:\u003c\/strong\u003e 2021+\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MMX","offers":[{"title":"Default Title","offer_id":55328887472469,"sku":"MMR13-1601","price":299.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/3327\/0357\/files\/mmx-MMR13-16018-0073f1.webp?v=1791967560","url":"https:\/\/shop.regalautosport.com\/products\/mmx-underbody-chassis-brace-bmw-m3-m4-g80-g81-g82","provider":"Regal Autosport","version":"1.0","type":"link"}
