M5 (F90)

Most owners start with sound and feel: a valved exhaust or midpipe, carbon intakes and SHFT paddle shifters, followed by an ECU tune. If you drive on track, upgrading brake fluid and pads is more useful than extra power, because the M5 weighs close to two tonnes. Lowering springs and carbon styling such as a front splitter or diffuser are popular next steps once the car drives the way you want.

The S63B44T4 is a strong engine and software alone typically lifts output well above the factory 600–625 PS. Established tuners advertise around 700 hp at the crank on the standard turbos with quality fuel, with more possible using supporting fuel and cooling upgrades. Results vary with fuel, weather and the car's condition, and all-wheel-drive chassis dynos read lower than engine figures, so compare like with like.

Often, yes. BMW hard-locked the Bosch DME on many cars with an engine computer produced from around June 2020 onwards, which covers most LCI M5s and the CS. These units usually need to be removed and bench unlocked before flash tuning is possible, while earlier DMEs can often be unlocked through the OBD port. Check your DME production date, not the car's build date, before booking a tune.

Yes. Kits such as KW's height-adjustable springs are designed for the M5 with its factory adaptive dampers, which keep working in all drive modes. They typically allow around 5–20 mm of adjustable drop front and rear. Remember the Competition already sits 7 mm lower than the standard car, so choose a ride height with tyre clearance and alignment in mind, and have geometry set after fitting. Fitment is shown on each product page.

The standard M compound brakes cope well with road driving and many owners report them holding up on track, but the weak points are fluid temperature and pad life, especially at the rear. A high-temperature brake fluid and a track-focused pad are the usual upgrades, and braided lines help keep pedal feel consistent. Cars with carbon ceramic brakes need different discs and pads, so match parts to your system.

Many do. The F90 M5 and F91, F92 and F93 M8 share the S63 V8, eight-speed gearbox, M xDrive and brake hardware, so items such as brake discs, pads, engine parts and some intake components are often listed for both. Exhausts, body panels and aero are model-specific. Save your car to My Garage at R44 and check the fitment listed on each product, or ask our team to confirm before ordering.
