G87 M2

Unit 17's M2 aero program

Each piece answers something about the stock car. The factory M Performance spoiler stops short of the trunk ends, so the OEM++ spoiler carries the shape edge to edge; it's the M2 part we sell most. The rear bumper looks high next to the low nose, so the 3-piece diffuser wraps around the exhausts to keep a low line across the back. The SPL1 splitter has vents molded in to let air through, mounts on OEM points with no drilling, and is sized to the bumper so it isn't a curb-scraper. The SPL2 is a one-piece alternative with a more aggressive front ledge, and the side skirts with winglets tie front and rear together. See them all under G87 M2 exclusives.

Grilles, ducts and trunks

Grille options include CS-style and CSL-style kidney grilles, a gloss carbon front grille, a dry carbon center grille and a lower center grille valance for the bumper. The front ducts come in V2 and V3 shapes, and the MP-style air inlets add carbon to the lower intakes. At the back, three CSL-style dry carbon trunks (V1, V2 and V3) replace the factory lid; check each listing for shipping, since large panels can be quoted separately.

Rear bumper trims

If you want carbon on the rear bumper without changing the diffuser, the rear bumper trim, rear bumper splitter and rear arch trims are add-on pieces with 3M tape pre-applied. Clean the surface and warm the tape during fitting, as the listings describe.

G87 or G42?

The M2 is based on the G42 2 Series coupe, and some rear spoilers here, including the OEM++, MP-style and CS-style, are listed for both. Grille, skirt and diffuser parts are listed for the M2 only, because it has its own bumpers and wider body. If you drive an M240i, check the fitment line before you order.

Materials and finish

Most M2 parts are pre-preg dry carbon, many with a 2x2 weave and a UV-resistant gloss clear coat. Some engine bay and interior pieces are also offered in matte or forged finishes, and the choices appear on each product page. The side seat covers come in bucket-seat and comfort-seat versions, so select your seat type.

Engine bay and interior

The engine cover, cooling shroud, oil cooler guard and CSL-style strut brace are shared with the G80 M3 and G82 M4, which use the same S58 engine. Inside, a couple of trims are made specifically for 2025-on cars, so match the listing to your model year.

Shipping and returns

Unless the product page shows a longer lead time, most orders ship within 5 business days. Parts marked Coming soon don't have a ship date yet. Test-fit before you paint or install: uninstalled parts can be returned within 14 days of delivery, installed parts can't.
