Description

Details

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. We offer the upper and lower parts separately because the upper sections work well on other cars such as the NB, NC, E36 and S550 Mustangs - and some people might just like the look of just one part.

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.

Great look
Installed on an NB Miata, with the bottom of the vent about 1" below the rock guard line. It seems impossible to rivet the middle part of the vent nearest to the door as the fender curves but the vent does not. If you do manage to squeeze the vent and fender close enough to rivet them, you will dimple the fender. If you just put a rivet in the fender hole to complete the look, no one will know and it won't affect the performance as far as I can tell.

I'd be concerned about removing the fender liners on a daily driver that sees rain/snow, but that isn't my car.

Otherwise took about 1.5 hours per side. The hole for the vent could be a tad larger (1/8" total) so you don't run into issues getting the vent fins to clear. Don't forget to drill the holes before you remove the template ;-)

Great look, especially with Singular hood vents and a red cowl stabilizer brace peeking out.
