DESCRIPTION

A fully functional diffuser for the ND Miata that reduces lift, reduces drag, and looks great too. We're big fans of aerodynamic parts that WORK, and Velox motorsports designed this unit in CFD specifically for the ND. If you're like us and want to geek out over all the technical details, you can view the full write-up at the link at the bottom of this page.

The unit is adjustable vertically to fit multiple aftermarket exhausts. Produced from aluminum, the unit can take quite a beating and still retain it's functionality and shape.

FITMENT NOTES: Fits with all of our RoadsterSport muffler options EXCEPT the Twin Tip Super Street. To fit this diffuser with the TTSS, you will need to add longer hardware with additional spacers to space the diffuser down enough to clear that muffler.

Construction:
5052 Aluminum
Durable black powder coat
Stainless hardware throughout
All brackets/hardware included for a full install

Design Features:
Organic Shape
Flat head riveted strakes (No rivet heads visible, flat bottom)
Simple Bolt on installation, no cutting required
Reduces drag
Significantly reduces lift

Verus Motorsports ND Rear Diffuser

Very happy with this diffuser, more than expected. I'd seen one at the track and thought it looked kind of flimsy, but man oh man this is a nice piece. Excellent instructions, if I recall I supplemented some of the hardware because I'm a bit OCD on that kind of thing. "Seat of the pants testing" it feels like it does indeed work, the car certainly seems to move around underneath me much less than before (80MPH or so and up). Track Day on August 6th will tell me more, but if nothing else it definitely closes off the "parachute" formed by the bumper facia, and it looks just cool as Hades. Summary: Dude, I'm stoked! I dropped some pics in the Gallery if you want to look.

Pretty straightforward install and fitment is good. I did it myself but an extra set of hands would make it easier. You will have left over fasteners when you are done. I used the largest nylon spacers in the back. I didn't need to in order to clear my Roadstersport race muffler, but wanted to get the diffuser as low as possible. No vibration or contact with the muffler. It definitely makes the back of the car look better, which is why I bought it. I can't comment on improved aero as I don't track my car. But based on my racing experience, it looks like it should generate legitimate downforce. It's a little pricey but it looks good, much better than a wing.
