BMW 2 F23 Parts

The BMW 2 Series F23 convertible ran from 2015 through 2021, and for a lot of us in the Bimmer community, it represents something genuinely rare: a compact, rear-wheel-drive drop-top with a proper manual gearbox option, a lineage tied directly to the beloved E46 and E92, and enough aftermarket support to keep you busy for years. This isn't the G-series with its controversial styling and drive-by-wire everything. The F23 still feels like a BMW should - communicative, balanced, and rewarding when you push it. If you picked one up and you're ready to start modding, you're in the right place.

The platform shares its architecture with the F22 coupe, which is good news because it means the parts ecosystem is deep. The 220i and 228i came stateside with the turbocharged N20 four-cylinder - a capable engine that responds well to tuning, though it does carry some known baggage we'll get into below. The real crowd-pleasers are the M235i and M240i variants. The M235i runs the N55 inline-six, a single-scroll turbo unit that bridges the gap nicely between the raw N54 twin-turbo era and the smoother B58. The M240i then replaced it with BMW's B58, and that engine is frankly one of the best platforms in the modern Bimmer world - dead reliable, big power on bolt-ons, and tuners like Burger Motorsports and BM3 have cracked it wide open. If you're shopping for a project car, the M240i convertible is the one to find.

Before you start building, know what you're dealing with. On N20-equipped cars, the timing chain tensioner is a legitimate concern - BMW extended coverage on this, but on older high-mileage examples you want documentation or a proactive replacement. Valve cover gaskets and oil filter housing gaskets weep on most of these engines by 60–80k miles, so budget for that if it hasn't been done. The N55 cars are generally more robust, but watch the VANOS solenoids and the charge pipe - the factory plastic charge pipe is a known failure point under boost, and replacing it with a quality aluminum unit from Mishimoto or Burger Motorsports is one of the first things you should do. On all F23s, the soft top mechanism is worth inspecting carefully on used cars - the hydraulic cylinders and seals can weep over time, and a full soft top service isn't cheap.

Suspension-wise, the F23 uses a familiar MacPherson front and multi-link rear setup. It's competent from the factory, but the OEM rubber bushings and strut mounts fatigue. If you're putting miles on this car or pushing it hard, a quality coilover setup transforms the chassis. Check out our full Suspension catalog for options from KW, BC Racing, and Bilstein - all well-supported for the F23 platform. While you're under the car, the front control arm bushings are worth refreshing on higher-mileage examples before you start dialing in alignment.

Brakes are another honest priority upgrade, especially if you're running the M235i or M240i and tapping into that power. The OEM rotors and pads are adequate for spirited street driving, but they'll fade under repeated hard use. Drilled or slotted rotors with a quality pad compound like EBC Yellowstuff or Hawk HPS for street, or Hawk HP Plus if you occasionally hit a track day, make a real difference you'll feel immediately.

The daily driver path on the F23 is genuinely fun and doesn't require you to compromise livability. Start with a Stage 1 ECU tune - on the B58, that means 380–400whp on pump gas with the right tuner. Pair it with a quality downpipe from VRSF or Active Autowerke (catted if you need to stay emissions-legal), and an Exhaust system that opens up that inline-six sound without droning on the highway. JB4 with BM3 backend is a popular dual-tune setup for guys who want flexibility. Add a set of 18 or 19-inch forged wheels - the F23 looks aggressive on wider rubber - and you've got a street car that eats sports cars at stoplight pulls while still being comfortable on a road trip. Browse the Wheels & Tires section for fitment-specific options.

For the track-day crowd, the convertible chassis does add some flex compared to the coupe, so stiffening the platform matters more here. A strut brace up front, quality coilovers, and upgraded sway bars should be on your list early. Drop down to a 200-cell high-flow cat or go full catless on a dedicated track car, and pair it with Engine supporting mods - upgraded intercooler, ethanol flex fuel kit if your tuner supports it - to keep IATs in check during extended sessions. A clean set of aero pieces from the M Performance line or aftermarket options in our Body & Aero section pulls the look together and adds genuine downforce at speed.

The F23 doesn't get the hype of the M2 or the E-series nostalgia crowd, but that's honestly part of what makes it a smart build platform right now. Prices are reasonable, the aftermarket is mature, and a well-sorted M240i convertible is a genuinely fast, genuinely fun Bimmer. Build it right and it'll remind you every time you drop that top exactly why you became a BMW person in the first place.
