BMW M240i F22 Performance Parts & Tuning Mods

Top Brands For BMW M240i F22 Mods

The BMW M240i F22 is well supported by leading performance and motorsport brands, making it easy to find quality aftermarket upgrades. Below you will find top manufacturers offering proven mods, from suspension and exhausts to intake, braking and styling parts.

Exterior Styling Mods for BMW M240i F22

To sharpen the look of your BMW M240i F22, you can mix and match exterior styling mods like body kits, front splitters, rear diffusers, boot spoilers, custom grilles and trim upgrades. These visual tweaks help your coupé stand out on the road, adding a more aggressive, track-inspired presence.

Handling & Suspension Upgrades

The BMW M240i F22 is a cracking base, but from factory it rides a bit soft, with noticeable body roll and safe understeer when pushed. Start with quality tyres, ditching run-flats for grippy performance rubber, and upgrade to fast-road brake pads and fluid for better bite and fade resistance. A big brake kit is worth considering if you do regular track days, giving more consistent stopping power and confidence at the end of a straight. Next, look at suspension tuning. Lowering springs or a matched damper and spring kit sharpen turn-in and reduce roll without ruining daily comfort, while fully adjustable coilovers let you dial in ride height and damping for proper track-focused agility. Chassis tweaks like uprated anti-roll bars, front strut braces and stiffer bushings tighten up the front end and rear stability, so the M240i feels more planted and eager in corners, with more precise steering feedback and better traction on exit.

Frequently Asked Questions

What are the best first performance mods for a BMW M240i F22?

The M240i F22 is quick out of the box, but the best first upgrades are usually an ECU remap, a high quality panel or intake kit, and a sports exhaust. A stage 1 map alone can give a very noticeable bump in horsepower and torque, while keeping everything within safe factory limits when paired with decent fuel.

Many owners also start with a set of lowering springs or coilovers and uprated anti roll bars. Sorting the handling early on makes the extra power easier to use and gives the car a more planted, confidence inspiring feel on fast road drives.

How much power can the B58 in my M240i handle safely with bolt on mods?

The B58 in the BMW M240i F22 is very strong, so with sensible tuning and proper supporting mods it can comfortably handle a healthy increase in power. A typical stage 1 ECU tune on a stock car, using good 99 RON fuel, usually keeps things well within the safe range for the standard turbo, injectors and internals.

With bolt ons like a freer flowing downpipe, intake, intercooler and a suitable stage 2 remap, you can see a solid uplift in power and torque for fast road and occasional track use. The key is regular servicing, quality oil, proper cooling and sticking to proven tuning packages rather than chasing headline dyno numbers.

Will tuning my BMW M240i affect reliability and daily drivability?

Done properly, tuning your M240i F22 should still leave you with a very usable daily that is smooth, quiet when you want it, and happy in traffic. Good ECU remaps refine the power delivery, sharpen throttle response and keep safety features like knock control fully active.

Reliability depends on how the car is driven and maintained. Warm the engine and turbo before pushing on, use quality fuel and oil, and stay on top of servicing. If you plan on repeated hard use, track days or high power levels, consider an uprated intercooler and fresh ignition components to reduce heat soak and misfire issues.

What supporting mods do I need for a stage 2 tune on my M240i F22?

For a typical stage 2 ECU map on the BMW M240i, you will usually want a high flow downpipe, a performance intake or panel filter, and an uprated intercooler. These upgrades help the turbo breathe more freely and keep intake temps in check, which allows the tuner to safely run a bit more boost and timing.

It is also wise to fit uprated spark plugs gapped correctly for tuned boost levels, and to ensure your cooling and brakes are in top condition. If you are planning regular track use, consider performance brake pads, fresh brake fluid and possibly stainless steel lines for more consistent stopping power.

What wheel and tyre sizes work well on a tuned BMW M240i F22?

The M240i F22 runs well on 18 or 19 inch wheels, with many owners upgrading to lighter rims for better response and grip. A popular fast road setup is 18x8 or 18x8.5 with a 225 or 235 section tyre up front, and 18x8.5 or 18x9 with 235 or 245 tyres at the rear, depending on ride height and camber.

On 19s, something like 19x8 and 19x8.5 or 19x9 is common, with 225 to 235 front and 245 to 255 rear tyres. Always check offsets, clearances and tyre profiles to avoid rubbing, especially if you have lowered suspension or run more aggressive camber for track work.

Will a sports exhaust or decat downpipe cause issues with MOT or emissions checks?

A cat back exhaust on the M240i is usually fine for MOT as long as it is not excessively loud and you keep the factory or a high quality sports catalytic converter in place. This type of exhaust upgrade mainly improves sound and flow, with a modest performance gain.

A decat or some race downpipes, on the other hand, can cause MOT emissions failures and warning lights, and are technically for off road or track use only. A high flow sports cat is often a better choice for a fast road car, giving improved flow and sound while keeping you on the right side of UK MOT rules when combined with a proper ECU tune.

How much should I budget for a sensible tuning package on my BMW M240i?

Costs vary, but for a sensible fast road build on an M240i F22 you might budget for an intake, cat back exhaust, intercooler and a quality stage 1 or stage 2 remap. Parts and mapping combined can easily run into four figures, especially if you add suspension, brake and wheel upgrades at the same time.

The most cost effective route is usually to plan a package rather than buying mods randomly. Decide on your target use, for example daily road car with the odd trackday, then choose performance parts that work together, such as matching springs and dampers, a proven ECU tune and supporting hardware that will not need replacing again when you decide to go a bit further later on.

Final Thoughts on the BMW M240i F22

The BMW M240i F22 is a cracking package straight out of the box, with that strong B58 engine, compact rear‑drive chassis and just enough refinement to daily without feeling like a compromise. Stock, it is quick, grippy and capable, but you can feel there is a lot of untapped potential in the drivetrain and chassis. With sensible power mods like an intercooler, intake, exhaust and software tune, you can unlock noticeable gains in torque and response while keeping things reliable for road and occasional track use. Keep the focus on quality performance parts and proper setup, and the car stays friendly to live with every day. The standard suspension and alignment are aimed more at comfort than committed driving, so the M240i can feel a touch soft and floaty when pushed. Upgrading to coilovers or sport springs and dampers, along with uprated anti‑roll bars and fresh bushes, tightens the whole car up without ruining ride quality. Wheel and tyre upgrades make a big difference too, giving you sharper turn‑in and more confidence in the wet and dry. These handling mods turn the chassis into something that really matches the punch of the B58 engine. There are a few known weak spots that enthusiasts often address early on, especially if power goes up. Heat management is one of them, so many owners fit a better intercooler, improved cooling hardware and use decent quality fluids to keep intake temps and oil temps under control. Manual cars can start to show the limits of the clutch with higher torque, so an uprated clutch and flywheel combo is a smart move for tuned builds. With these areas sorted, the M240i stays strong and dependable even at higher performance levels. Styling and aero tweaks finish the package, from subtle splitters and diffusers to more aggressive wheels and exhaust tips that give the car a bit of presence without going over the top. Put it all together, and a well thought‑out BMW M240i F22 build is quicker, more planted and more engaging, yet still civilised for commuting and long trips. The key is choosing upgrades that work together, not just bolting on random bits. Get the balance right and you end up with a car that feels like your own personal take on what BMW should have built from the factory, tailored to your driving style and ready for whatever roads or track days you throw at it.
