• Intake and turbo: Dinan and MST cold air intakes, Dinan carbon turbo inlet pipes and charge pipes, and Turbosmart blow-off valves.
• Exhaust: Scorpion sports cat and de-cat downpipes, a Scorpion half system and Dinan axle-back exhausts.
• Cooling: CSF and Dinan heat exchangers for hot days and track use.
• Suspension: AST coilovers and lowering springs, Öhlins Road & Track coilovers, Dinan springs, sway bars and strut braces, plus HARDRACE and SPL arms and bushings.
• Brakes: Alcon front and rear big brake kits.

• Body style: some springs and exhaust parts are made for one body only. Check the title for coupe (G22), convertible (G23) or Gran Coupe (G26).
• Adaptive dampers: cars with adaptive M suspension (EDC) need an EDC-ready kit or a cancellation kit. AST lists EDC and non-EDC versions.
• Engine version: the 2024 facelift brought an updated B58. Some intake, turbo inlet and blow-off valve parts suit one version only, so check the title.
• Not the M4: the M4 uses the S58 engine and different suspension, so its parts won't suit the M440i. Shop the M4 page instead.

Have a qualified workshop fit suspension, brake and engine parts. Get a wheel alignment after any suspension change. Downpipes and intakes usually need a tune to run at their best; ask us if you're unsure.
