Wheel wells are ugly places, aerodynamically speaking. The wheel is whipping around in there, there are vortices squirting off the front of the tire, there's high pressure and it's hot. If you can extract air out of there, you'll get improved brake cooling, better engine cooling, lower tire temps and better organized airflow.
There's never been a really clean way to do that with a Miata. There have been various replacement fenders over the years, but the suppliers come and go. You can do a lot of careful work with an angle grinder and braces, but it's not easy and often looks a little...homemade.
Enter the Left Lane Designs fender vents! They're constructed from powdercoated laser-cut aluminum. Simply use the existing template as a guide, cut away your fenders, and rivet in the vents. The end result is probably stiffer than stock and will extract large amounts of air from your front wheel wells.
The NB style is a single large vent. The NA style is split into an upper and lower section because of the groove in the stock fender.
While the two-piece version was designed around the NA and the single-piece was designed around the NB, both work well on NCs and NDs, as well as other cars. You can also use the NA vents on an NB, although you can't use the NB vents on an NA (there's a body line in the way). Note that we no longer offer the uppers and lowers individually.
Sold in pairs. Each kit includes a vinyl template, rivets, and rubber edge trim. Watch out on installation, there is a left and right side!
If you'd like to see how these would look on your car, you can download a PDF of the template, print it, and test-fit it on your fender.
