Splitter+Lip Options
Splitter sizes can be generally adjusted +/- 1
| Lip | Front | Side |
|---|---|---|
| Bimmerworld Riser | 6.5" | 3.5" |
| ACS Poly | 4.5" | 1.5" |

Alumalite
Aluminum composite panel with a high-density corrugated polypropylene core
Alupoly
Aluminum composite panel with a solid polyethylene core
Sturdy, Light Construction
Lightweight aluminum composite material that is highly water resistant. The unique core design makes it light, but very rigid.
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.
<a href=”https://thebuildjournal.com/shop/all-products/aerodynamics/mounting-hardware/buildjournal-splitter-brace/” target=”_blank” rel=”noopener noreferrer”>Splitter Brace</a> (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.

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.
