RGR TURBODISCO for 4x100 - 15" Wheels

SKU: TD.6U1588.36 / TD.FP158.28 / TD.KO159.36 / TDS1158.25

Introducing the RGR Turbodisco, the first wheel covers designed to truly bolt-on to your existing wheel.

Inspired by the "Turbofan" wheel covers from the 80s, the RGR Turbodisco is designed to provide the aerodynamic benefit of having a wheel cover while allowing hot air to escape the wheel.

Designed like the original Turbofans, the Turbodisco uses fins that are exposed outside of the wheel to create a pressure difference that aids in the extraction of hot air from the wheel area and just like the original they provide drag reduction benefits by allowing the air to run smoothly around your wheel/tires.

On preliminary CFD testing the Turbodisco have reduced drag on our NB Miata model, with and without our aero parts.

In order to make sure that the Turbodiscos did its job, it underwent extensive testing, CFD simulations, and several iterations. Feel free to visit our Instagram or Facebook page (links at the bottom left corner of our website) to check out the engineering process of this part.

The Turbodisco gets mounted to the wheel using Allen bolts, these bolts thread onto open-end lug nuts.

This kit includes the necessary open-end lug nuts, we use our RGR Titanium M12X1.5 lug nuts. PLEASE MAKE SURE YOUR CAR USES THIS SIZE LUG NUTS BEFORE ORDERING.

We got 4 Turbodiscos available, each one designed to fit each specific wheel

1. 15x8 - 4X100 - ET28 Enkei RPF1
2. 15x9 - 4x100 - ET36 Flyin' Miata Kogeki
3. 15x8 - 4x100 - ET36 949 Racing 6UL (Gen 1 - 3)
4. 15x8 - 4x100 - ET25 Advanti Storm S1

Two (2) Turbodisco finishes are available; Bare Aluminum and Carbon Fiber.

If you wish to get a more customized look, RGR has partnered with SpinnyWoosh to offer custom TURBODISCO graphics, you can get them here:

The Turbodisco can be ordered assembled or disassembled.

The disassembled option allows for easier customization (custom graphics, powder coating, anodizing) and since it saves us money in packaging and assembly, we transfer those savings to you.

Notes:
- As of September 2025 every Turbodisco includes our updated center covers with CNC machined inserts. This update is available for existing Turbodisco owners, please reach out if you wish to get it.
- Wheel covers are not replacement for brake ducts. They are not brake cooling devices, they are aerodynamic devices.
-Price includes shipping to the continental USA, for anywhere else reach out for a custom quote before ordering.
-Turbodiscos are sold as a set of two (2).
