Buildjournal Sideskirt Splitter – E46


Increase downforce with our E46 Sideskirt Splitter. The sideskirt is a complementary aerodynamic component to split the wind on the sides of the car to above and below the chassis. The sideskirt splitter extension reduces wind spill so you retain faster moving air on the bottom of the chassis while the slower moving air stay above. Fits on E46 M3 and non-M models.

E46 M3 Sideskirt 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.

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.
