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.

Weighs Less Than 6 lbs (Alumalite)

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.

Splitter Guard (Add-On)

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.

Splitter Brace (Optional)

It is highly recommended to reinforce the front splitter with a Splitter Brace. This provides maximum frontal support of the splitter over hang without having to use splitter rods.

Splitter Brackets (Optional)

100% compatible with our splitter brackets.

Splitter Extension

Extend the rear of the splitter by an additional 9" and accelerate low pressure air underneath the chassis. This is a separate panel that bolt's on to the E46 M3 Quick-Release Splitter Bracket Full Kit with Rear Support.

❗ Additional reinforcements for the Race Splitter, such as front splitter rods, are recommended to ensure stability during high-speeds. It is also critical to set the angle-of-attack (AOA) of the Race Splitter to eliminate excessive downwards angle at high-speeds. We recommend slightly positive (facing upwards) AOA from neutral 0 degrees.
