Exterior Styling Mods for BMW M5 Competition F90

To sharpen the presence of your BMW M5 Competition F90, you can pick from a range of exterior styling upgrades including body kits, spoilers, splitters, diffusers, custom grilles and more. These visual mods help you dial in a more aggressive, track-inspired look or a cleaner, more individual style on the road.

Handling & Suspension Upgrades

The F90 BMW M5 Competition is rapid out of the box, but it is a heavy car and can push into understeer if you are really leaning on it. Start with quality tyres, going for a more track focused performance compound if you do regular spirited driving, as this alone sharpens grip, turn in and braking stability. Match that with uprated pads, high boiling point brake fluid and, if you are serious about track days, a big brake kit to give stronger, more consistent stopping power and better pedal feel. Once the basics are sorted, look at suspension tuning. Lowering springs or height adjustable coilovers bring the centre of gravity down and control body roll, so the M5 feels more agile and planted in quick direction changes. Performance dampers and stiffer anti roll bars help tidy up the slight floatiness the factory adaptive setup can show on bumpy B roads, improving composure without ruining comfort if you choose sensible spring rates. Add chassis braces and upgraded bushings to sharpen steering response and rear axle stability, and you end up with an M5 that feels much more precise and rewarding in the corners.

Frequently Asked Questions

What are the best first performance mods for a BMW M5 Competition F90?

The most popular first upgrades on an M5 Competition F90 are an ECU remap or tuning box, high quality panel or intake system, and a less restrictive exhaust or OPF / secondary cat delete where appropriate. These give noticeable gains in horsepower and torque without turning the car into a full track build.

Many owners also start with simple hardware like uprated wheel and tyre setups, performance pads, and brake fluid. These do not add power, but they make a big difference to how the car puts its power down and how confident it feels on fast road or occasional track use.

How much power can a stock BMW M5 Competition F90 handle on standard internals?

The S63 engine in the F90 M5 Competition is very strong from the factory. With a sensible stage 1 remap and supporting mods such as upgraded intakes and a freer flowing exhaust, it is common to see healthy gains in power and torque while staying on stock turbos and internals.

For higher stages, such as hybrid turbos and more aggressive boost targets, you are pushing the limits of the standard cooling, fuel system and drivetrain. At that level, we recommend a proper health check, upgraded cooling, and regular maintenance to keep reliability in line with the extra performance.

Is a stage 1 remap safe for daily driving my F90 M5 Competition?

A well calibrated stage 1 ECU remap that stays within sensible boost, timing and torque limits is generally safe for daily use, provided the car is healthy and properly serviced. You should always use high quality fuel, ideally super unleaded, and keep on top of oil changes and spark plugs.

Stage 1 tuning is designed to work with stock hardware, so there is no requirement for big extra mods, but pairing it with a performance intake and freer flowing exhaust can help manage heat and improve drivability. The key is using reputable software and having the tune installed by a specialist who understands BMW M cars.

What wheel and tyre sizes work well on a tuned BMW M5 Competition F90?

The F90 works very well with 20 inch or 21 inch alloys, although many owners stick with 20 inch rims for a better balance of grip, comfort and cost. A common performance setup is a wider rear tyre, with premium UHP rubber to help manage the extra torque from a remap.

Offset and width need to be chosen carefully so you avoid rubbing and maintain proper clearance over the brakes and suspension. If you are going lower on springs or coilovers, speak to us before ordering wheels so we can advise on a safe fitment that suits fast road and occasional track use.

Will fitting an aftermarket exhaust or OPF delete affect MOT or warranty on my F90 M5?

Any change to emission control components, such as removing primary cats or OPF / GPF, can have MOT and legal implications in the UK. Many owners instead go for performance back boxes, mid pipes or OPF back systems which improve sound and flow while keeping key emission parts in place.

Warranty impact depends on your dealer and the nature of the modification. Manufacturers can decline related claims if they believe a mod contributed to a failure. If warranty is important to you, consider more subtle upgrades and keep all original parts so you can return the car to stock if needed.

Do I need upgraded cooling on a tuned BMW M5 Competition F90?

For light tuning such as a stage 1 remap with basic bolt on mods, the factory cooling is usually adequate for normal road use, as long as everything is clean and in good condition. It is still a good idea to use quality oil and allow the car to warm up and cool down properly.

If you plan on regular track days, spirited driving, or higher power levels with stage 2 and above, uprated charge coolers, radiators or additional cooling hardware can help keep intake temps under control and protect the engine and turbos. This supports consistent performance rather than chasing unrealistic power figures.

How much does it typically cost to tune a BMW M5 Competition F90?

Costs vary depending on how far you want to go. A simple stage 1 ECU remap is usually the most cost effective route to extra horsepower and torque, and can often be done in a single visit. Adding intakes, downpipes, exhaust systems, and suspension upgrades will increase the budget but also refine the overall package.

We always suggest planning a tuning path rather than buying random parts. Decide if you want a quick fast road upgrade, or a more serious track focused build, then we can recommend a combination of performance parts that offers good value and keeps the BMW M5 Competition enjoyable and reliable.

Final Thoughts On The BMW M5 Competition F90

The BMW M5 Competition F90 is already a seriously capable super saloon, with huge twin-turbo power, a smart xDrive system and enough refinement to do daily duty without drama. Out of the box it is rapid, comfortable and very grown up, but that also means it can feel a bit muted for drivers who really want to explore its potential. That is where sensible performance mods and tuning upgrades come in, waking the car up without ruining its dual‑purpose nature. Stock, the F90 can struggle with intake temps and heat management when pushed hard, especially on repeated pulls or track time. Breathing upgrades like high-flow intakes, uprated intercoolers and a freer flowing exhaust system help it stay consistent and give more punch, while software calibration brings the S63 to life with sharper throttle and stronger mid-range torque. Many owners also improve the factory brakes and pads to cut fade, and fit quality suspension upgrades or coilovers to tighten up body control without wrecking the ride. Styling tweaks and chassis mods let you dial in the attitude to match the performance, with lightweight wheels, more aggressive tyres and subtle aero giving the M5 Competition a purposeful, motorsport-inspired feel. Kept sensible, these upgrades respect the car’s reliability and day-to-day usability, so you still have a comfortable commuter that can turn into a very serious weapon on demand. With the right mix of performance parts, handling upgrades and tasteful cosmetic changes, your BMW M5 Competition F90 can move from “fast executive” to a truly personal build that feels special every time you drive it.
