BMW G20 330i & M340i Body Kits
3 products
Each G20 body kit here works like a menu: you choose the pieces for your 330i or M340i sedan instead of a fixed set. There's a listing for the 2023-on LCI and separate listings for pre-LCI cars from 2019 to 2022.
Every piece is pre-preg dry carbon with a 2x2 weave and a gloss UV-resistant clear coat. They're add-on parts for your factory bumpers, sills and trunk, not a widebody conversion.
BMW G20 330i & M340i Body Kits buying guide
Start with your G20's model year
BMW gave the G20 new front and rear bumpers at the facelift for the 2023 model year, so the kits are split by version. The LCI kit is listed for 2023-on cars, and the pre-LCI kits for 2019 to 2022. Every listing names the 330i and M340i sedan. Aftermarket G20 aero like this is generally made for the M340i and for 330i sedans with the M Sport package, so send us a photo of your car first, as each listing recommends.
What each G20 body kit listing offers
- LCI, 2023 on: a V1 or V2 front lip, front canards, side skirts, a diffuser with no light (V1), a horizontal light (V2) or a vertical light (V3), and a V1 spoiler or a DF-style V2 spoiler.
- Pre-LCI, TK listing: a V1 or V2 front lip, canards, standard or long-wheelbase side skirts, a rear bumper trim, a diffuser on its own or with rear splitters, and a spoiler. It uses the factory mounting locations where they apply.
- Pre-LCI, KB listing: a front lip, canards, side skirts, a diffuser, a rear bumper trim, and a DF-style spoiler or a second spoiler design.
Between the pre-LCI listings, the TK gives you two lip designs and a diffuser with splitters, while the KB gives you two spoilers. Choose the standard side skirts for a US car.
Fitting it in stages
Because you order by the piece, you can start with a front lip and canards and add the rear parts later. With several parts to fit, a professional installer is the sensible route. Test-fit every piece before it goes on for good: installed parts can't be returned, while a part that doesn't fit the car on its product page is covered by our fitment guarantee if you contact us first. For a spoiler on its own, see the G20 spoilers, and for the rest of the car, all G20 3 Series parts.
Frequently asked questions
Is the G20 body kit a widebody kit?
No. The pieces are add-ons for the factory bodywork: lips and canards on the front bumper, side skirts along the sills, a diffuser and trims on the rear bumper, and a spoiler on the trunk. None of the listings includes fender flares or wider panels, so your car keeps its factory width.
Which side skirts should I choose on the pre-LCI TK kit?
The standard side skirts. The long-wheelbase version is for the G28, a 3 Series stretched by about 4.3 inches in wheelbase that BMW sells in China and some other Asian markets. Every G20 sold new in the US has the standard wheelbase, so the standard skirts match its sills.
Can a 330i without the M Sport package take these parts?
Ask us before ordering. The kits are listed for the 330i and M340i, and aftermarket G20 aero like this is generally made for the M340i and M Sport 330i bumpers. A 330i with the standard bumpers may need different parts. Text photos of the front and rear of your car to 609-525-4865 and we'll confirm which pieces fit.
What are the light options on the LCI diffuser?
The LCI listing offers the diffuser as V1 with no light, V2 with a horizontal light or V3 with a vertical light. The listing doesn't explain how the light is wired or what it does, so ask us before choosing V2 or V3 if that matters for your build.
