BMW 3 Series G20/G21 Tuning Parts

Here you’ll find model-specific facelift and body kit sets for BMW 3 Series G20 (sedan) and G21 (Touring) from 2018: body kits, bumpers, lips, diffusers, side skirts, spoilers, kidney grilles, mirror caps, lights, hoods, exhaust tips, mats, and mud flaps. Choosing the right part depends on three things: pre-facelift 2018–2022 or facelift (LCI) 2022+/2023+, bumper type (Base, M-Sport, M-Performance, M340i), and body style—sedan or Touring.

How to identify your BMW G20/G21: year, bumper, body style?

• Pre-facelift or facelift. In product names, pre-facelift is marked “2018–2022”, facelift is “2022+” or “2023+”. Kidney grilles, lips, diffusers, and bumpers are different for these versions. If the car has already been converted, go by the bumper that is actually installed, not the production year.
• Bumper type. Lips and diffusers are made for a specific bumper: standard (Base), M-Sport, M-Performance, or M340i. The label “for G80” means the part is for the M3 G80 bumper—if you have a regular G20, choose options marked Base or M-Sport. A style name alone isn’t enough to choose a lip: send the manager a photo of your bumper.
• Sedan or Touring. Trunk lid spoilers and rear window trims are made for the G20 sedan (some also fit M3 G80); for the G21 Touring there is a separate DPT spoiler. Trunk mats and the stainless rear bumper protector are also sold separately for G20 and G21—the body style is stated in the product name.

What facelift kits, body kits, and bumpers are available for the G20?

To convert a pre-facelift car to the facelift look, there are facelift kits: “to 2023, M-Sport” and “to G80 M3 2025”. The 2023 M-Sport kit includes front and rear M-Sport bumpers, side skirts, M-Sport kidney grilles, the active air shutter, Laser front headlights 2023+, and M340i exhaust tips. If you buy lights separately (Laser headlights 2023+ or taillights 2023+), confirm with the manager whether any wiring modifications are needed for your specific car.

Among the body kit sets there is M-Sport for 2018–2022 (front and rear bumper, side skirts) and M-Sport for 2023+ (bumpers, side skirts, M340i tips). Also sold separately are front bumpers: M-Sport for 2018–2022 and for 2022+, M340i 2023+, and an M3 G80 design bumper for 2018–2022. For the M3 style, there are aluminum hoods, steel M3 Style fenders, and carbon hood and trunk lid. Bumpers and kits install into factory mounting points and are supplied unpainted—before painting, parts are test-fitted and panel gaps are checked. You can install the kit at DD Tuning’s network of certified service centers—your manager will recommend the nearest one.

How to choose a lip, diffuser, side skirts, and spoiler for the G20?

Front bumper lips (also called “lip”, “splitter”, or “skirt”) are available in gloss black ABS plastic—DPT, EuroCap, AC, CS, MP and FD styles—and in carbon fiber, separately for Base, M-Sport 2018–2022, M-Sport 2022+, and M-Performance. Rear diffusers are selected both for the bumper and for the exhaust: for M-Sport 2018–2022 there are versions for round tips and for rectangular tips; separate ones for 2023+ and for M340i; and options with LED. For M-Sport side skirts, ABS and carbon add-on trims are available.

Trunk lid spoilers are available in M3, M4, MP, PSM, P, V and OEM-Style designs—in gloss black, paint-ready, or carbon fiber; there are also rear window trims. The installation method is listed in the specs of each spoiler.

What kidney grilles, mirror caps, and accessories are available for the G20/G21?

Kidney grilles—M-Look, 1 Bar, Diamond Black, Diamond Silver, and M-Color—are available separately for 2018–2022 and for 2022+; for the facelift there are LED versions and the active air shutter; for G28 there is a separate option. Mirror covers come in two types: self-adhesive covers that mount over the OEM cap, and M-Look caps that replace the OEM ones and clip in; carbon versions are also available.

For the interior and daily driving: floor mats—EVA in several colors, textile, rubber Carsuit and Stingray (trunk mats are sold separately for G20 and G21), model-specific rubber-plastic mud flaps for both body styles, LED modules for headlights, M340i and M3 exhaust tips, and roof cross bars.
