Description

Wing
The GT250 is APR s low-drag airfoil, with an excellent lift/drag ratio, and lightweight pre-preg carbon fiber construction. Integrated carbon fiber gurney flap is included. This wing has already proven itself at a high level, but until now has always required entirely custom work to put on a Miata. These are built by APR to Singular’s dimensional specs, with custom mount spacing and an overall width of 64″, the maximum allowed by NASA (max width of the car). The wing is finished with a UV-stable clear coat.

*Wing can be made at a different overall width upon request, up to 72″ wide.

Endplates
Over the past several years we’ve done extensive testing with dramatically increasing the efficiency of the wing (more downforce with less drag) with optimized endplates. Naturally, this kit includes our latest V3 endplates that incorporate all that has been learned, with optimized size, integrated gurney flap trailing edge, and vortex generating profile on the upper edge.

Note: pictures of the wing on cars show the previous version endplates, but now you are getting our latest V3 endplates included with this wing.

Uprights
The main uprights are 6061 aluminum solid units for strength and low drag. Powdercoated in a signature “chrome” finish. Adjusting the angle of attack of the wing is done via a series of holes for the front two bolts which creates less drag than a turnbuckle adjuster. Available range: -5 to +15

Mounting
The uprights join to the body in the rain rail of the trunk. This is a rigid part of the chassis which transfers the wing s force directly to the chassis rather than onto the flexible trunk lid. This also eliminates the large mounting “foot” that is usually needed on top of the trunk lid, resulting in super smooth airflow over the trunk and under the wing. You simply drill the mounting holes for the bolts and trim the edge of the trunk lid to clear the mounts.

*Once the trunk lid is trimmed, the trunk is completely functional, and the trunk lid can open fully on its hinges*

Wing position
The higher and further back the wing is placed, the “cleaner” the airflow to it, and the better it performs. The uprights are back-swept dramatically to achieve wing positioning similar to what is usually only possible with rear frame rail mounting solutions, but with less weight/complexity and more rigidity. The rear of the airfoil is 5″ behind the rear-most point of the bumper. Airfoil height is optimized for most competition classes – just a hair below the highest point of the hardtop.

Shims
This ideal mount location usually creates difficulties because the sides of the trunk sit at an angle, which makes mounting a wing’s upright to them require multiple bends. Included in the kit are a pair of small 3D printed shims to solve all of this. This 3 dimensional shim corrects all the funky angles of the trunk edge to give the uprights a solid and vertical mounting surface. The angle corrections in the shims are an average between the NA and NB, so that the same shims and corresponding bends in the uprights work for all 1990-2005 Miatas.

Hardware
Every nut and bolt needed for install included. All hardware is metric class 10.9, with corrosion resistant coatings or stainless steel used throughout.
