BMW 4 Series (G22, G23 & G26) Performance Parts & Upgrades
Performance parts for the BMW 4 Series G22 Coupé, G23 Convertible and G26 Gran Coupé, built from 2020 onwards, including the B58-powered M440i. Our range focuses on sound, braking and handling upgrades with proven fitment.
G22 Suspension, Coilovers & Geometry
The G22 is a heavy, refined coupé tuned for comfort. Lowering the car and a bespoke geometry setup reduce body movement and make it feel more agile on the road. We stock coilovers and dampers from AST.
G22 Exhausts & Sound
Choose from Akrapovic titanium exhaust systems.
G22 Brakes
Endless brake pads in compounds to suit fast road driving through to sustained track use.
MMX Upgrades for the G22
Precision-engineered, UK-made MMX parts for the G22, including hubcentric wheel spacers, billet engine bay parts and oiling, cooling and chassis upgrades.
G22 Engine & Ignition
Supporting upgrades including Mantis performance ignition coils and MOTUL engine oil to keep your engine healthy under hard use.
G22 Wheels & Tyres
Nankang performance tyres to complete your build.
Fitting & Geometry Setup for Your 4 Series
Parts are only half the story. At our workshop in Stratford-upon-Avon we fit everything we sell and finish the job with ride-height setting, corner weighting and a bespoke geometry setup tailored to how you use your G22. It is what we are known for, and it is how you get the full benefit of every upgrade.
