This is our BimmerWorld E46 M3 Carbon Undertray -- as used in our complete E46 M3 Splitter/Undertray Kit, offered for purchase separately as a race replacement or spare. The matching splitter (sold separately) is intended as a track/race part and reduces ground clearance - not suggested for street use.  We offer this piece as a replacement part, available separately for more convenient damage replacement.

Effective - When used with our carbon splitter (sold separately) this fully enclosed undertray helps maximize downforce and maximizes efficiency by smoothing air flow under the car as far back as possible.

Lightweight - Reducing weight in front of the front tires has a huge positive effect on handling.

High Quality - The undertray is constructed as a honeycomb core composite by a manufacturer rooted in ALMS, Rolex, and other race parts. These parts will take a beating!

Damage Replacement - In the event of damage, this piece can potentially be repaired (send pictures for quote).

Fits E46 M3 only. 

Made in USA

BimmerWorld race carbon parts are designed solely to improve performance. Surface finish and appearance are not priorities in our racing parts. Carbon may be unfinished or sometimes with a minimal clearcoat (for UV protection). You will not find high gloss finishes here for style points. If your priorities are a show car shine there is no shortage of cheaper carbon-wrapped fiberglass or plastic pieces on the market. These are usually loaded with fiberglass, filler, resin, and many clearcoat layers that make them too heavy or not rigid enough for real world competition use. If you wish to apply a finish we suggest vinyl wrap or a light filler skim coat and then paint. In any case, professional prep and installation are strongly advised.
