BMW 3 Series (E90, E91, E92 & E93) Performance Parts & Upgrades
Performance parts for the BMW 3 Series E90 saloon, E91 Touring, E92 Coupé and E93 Convertible, including the 335i with its N54 and N55 twin-turbo and turbo straight-sixes, and the V8-powered E92 and E93 M3. The E9x is one of the most popular BMW platforms to tune.
E9x Suspension, Coilovers & Geometry
The E9x has a fine chassis, but standard and even M Sport suspension can feel soft and floaty when driven hard. Quality coilovers or lowering springs tighten body control, and a bespoke geometry setup sharpens turn-in and stability. We stock coilovers and dampers from KW and AST and Eibach lowering springs.
E9x Cooling & Intake
The N54 and N55 in the 335i are famous for heat soak once tuned, and cooling is the foundation of a reliable build. Upgrade with AIRTEC intercoolers and cooling upgrades.
E9x Exhausts & Sound
Choose from Akrapovic titanium exhaust systems.
E9x Brakes
Endless brake pads in compounds to suit fast road driving through to sustained track use.
MMX Upgrades for the E9x
Precision-engineered, UK-made MMX parts for the E9x, including hubcentric wheel spacers, billet engine bay parts and oiling, cooling and chassis upgrades.
E9x Engine & Ignition
Supporting upgrades including Mantis performance ignition coils to keep your engine healthy under hard use.
Fitting & Geometry Setup for Your E9x
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 E9x. It is what we are known for, and it is how you get the full benefit of every upgrade.
BMW E9x Upgrade FAQs
Do these parts fit the E92 M3?
Some do, but the V8 M3 uses M-specific suspension, brakes and engine parts. Look for M3 (E92 | E93) in the fitment list. Fitment is listed on every product, and if you are unsure, send us your registration and we will confirm.
Which intercooler do I need for my 335i?
N54 and N55 cars use different intercoolers and charge pipes. Check your engine code, or send us your registration and we will confirm.
