RGR NA Miata "ULTRA" V2 Chassis Mounted Front Splitter Kit

RGR Sport Splitter (NAA-FMU / NAA-SMU)

The RGR ULTRA Splitter is our more track-oriented and largest splitter offering. It provides real aerodynamic performance while remaining completely bolt-on, requiring no drilling, cutting, or permanent modification.

Designed for easy installation and removal, the ULTRA Splitter leaves no marks on your car and offers a lightweight, chassis-mounted, 5-way adjustable design.

Designed to take a beating, the mounting setup is constructed from high-grade aluminum, while the blade is made from HPDE Plastic.

Other unique features are the inclusion of threaded inserts on the Splitter Brackets
and new Chassis Mounts designed for easy slide-in-out splitter install and removal

Mounting Options
Forward Mount (NAA-FMU): Mounts further forward; ideal when space allows.

Standard Mount (NAA-SMU): Mounts further back, includes additional reinforcements. Provides more space directly behind the front bumper.

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).
