Front lips and splitters both mount under the front bumper, and the names are often used interchangeably. They are not quite the same part.
Front Lip
A front lip is a thin extension that follows the shape of the bumper. It lowers the front visually, slightly reduces the air going under the car, and takes the scrapes that would otherwise damage the bumper.
Splitter
A splitter is a flat plane that sticks out forward of the bumper. Air hitting the top of it creates high pressure, while air under it speeds up and drops in pressure. The result is real front downforce, especially when paired with a flat undertray. Track splitters are usually supported with rods to the bumper.
Which One Do You Need?
- Daily driver: a lip. More forgiving over driveways.
- Track car: a proper splitter with support rods to balance a rear wing.
- Drift car: a cheap, replaceable lip you don't mind destroying.
Popular options include the 2021+ Subaru BRZ front lip and the 2016-2021 Honda Civic front lip.
Fitment Tips
- Check clearance at ride height before drilling.
- Use rivnuts or plastic push clips that can break away on impact.
- Approach steep driveways at an angle.
