Mazda MX-5 Miata Speedster strips the roadster to its essence

For the 2015 SEMA show, Mazda made its MX-5 Miata roadster even lighter with a concept that shaves even more mass in the pursuit of performance.

Dubbed Speedster, this MX-5 concept is more than 250 pounds lighter than the standard MX-5 Club.

Less mass = more performance.

Mazda starts by ditching the folding soft top.

In its place, there's a double-hump tonneau that smooths out the roadster's aerodynamics.

We're told that there's storage for a pair of helmets and two sets of goggles beneath the carbon fiber tonneau's humps.

The Speedster's doors are made from carbon fiber as well, but painted to match the body's custom blue ether color. Frankly, we're surprised Mazda didn't skip the paint to save even more grams.

The grille is a minimalist piece with the word "Speedster" molded in.

An adjustable coilover suspension lowers the roadster by 1.2 inches compared to the stock Miata.

Custom 16-inch Rays Extreme Gram Lights wheels fill the wells and are shod with super sticky Kumho Ecsta racing slicks.
