Will this diffuser and splitter fit my BMW M4 exactly?
Yes, this combo is engineered specifically for the G80, G81, G82, and G83 M4 models. Custom fitment ensures a seamless, factory-like finish with no modifications required.

Is professional installation necessary?
While the bolt-on design allows for DIY fitting, professional installation is recommended to guarantee proper alignment, secure fastening, and correct wiring of the integrated brake light. Contact Project Styling in Southend-on-Sea for fitting services.

What finish does the carbon fibre have?
The diffuser and splitter feature a premium glossy carbon fibre finish that enhances the M4's aggressive appearance and adds a high-end, motorsport-inspired look.

Will this reduce weight and improve performance?
Yes. Carbon fibre is both lightweight and strong, so this upgrade reduces overall vehicle weight, which can improve handling and performance, whilst the aerodynamic design increases downforce and stability at speed.
