E46 M3 Front Splitter

Sturdy, Light Construction

Our splitter is made with 0.25" Alumalite material which is an aluminum composite with a high-density corrugated polypropylene core that is highly water resistant. The unique core design makes it light, but very rigid which is important for high wind resistance.

Extended-Length Design

Get smooth airflow with our extended-length design and increase downforce with faster moving air below the chassis.

Weighs Less Than 10 lbs

The Alumalite material core is made with a corrugated plastic with 2 thin aluminum sheet sandwiching the core. If you're trying to reduce weight, this is a better option than wood, ABS plastic or Alupoly.

U-Channel Kit (Optional)

Our splitter is designed to work in conjunction with our Quick-Release Adjustable Front Splitter Brackets. The splitter extends all the way back to the front brace plate making a seamless connection for smoother and faster airflow underneath the chassis.

Splitter Guard (Optional)

For those that want an extra layer of protection from road debris, our plastic splitter guard is a great add-on. It also improves the aesthetics of the lip.

❗ Additional reinforcement for the Race Splitter is recommended to ensure stability during high-speeds. It is also critical to set the angle-of-attack (AOA) of the Race Splitter so there is not excessive downwards angle at high-speeds. We recommend slightly positive (facing upwards) AOA from neutral 0 degrees.
