RGR NB Miata "SPORT" Chassis Mounted Front Splitter Kit

RGR NB Miata "SPORT" Chassis Mounted Front Splitter Kit
Fitment: 1999-2005 NB Miata

The RGR Sport Splitter bridges the gap between purely cosmetic splitters and full track-oriented aero. It provides real aerodynamic performance while remaining completely bolt-on, requiring no drilling, cutting, or permanent modification.

Designed for easy installation and removal, the Sport Splitter leaves no marks on your car and offers a lightweight, 4-way adjustable design. Smaller than our Ultra Splitter, it’s more practical for everyday use while maintaining high performance and a clean, functional look.

*** Please note that the Red Miata in the pictures has an aftermarket lip above the splitter that we do not supply ***

Mounting Options

• Forward Mounts (NBA-FMS): Mounts further forward; ideal when space allows.
• Standard Mounts (NBA-SMS): Mounts further back for more space up front, includes additional reinforcements, & may require splitter rods depending on vehicle setup.

Different cars have different space constraints—such as oil coolers or intercooler piping—so mount choice should be based on your configuration.

The Splitter blade is also optional in case you wish to make your splitter from another material. We can cut you a template in carboard or you can go the DIY route (reach out for more info).
