When considering a performance backbox for your MX-5, high flow and good looks are important, but what about weight? Every little bit of weight loss helps in these low powered sports cars and RoadsterSport understands that. This RoadsterSport backbox weighs in at just 12lbs (5.45kg), which is a huge difference when you consider the factory item weighs over twice that. Made entirely from polished stainless steel, this backbox has a lifetime warranty, uses stock hangers, and includes mounting gasket and all hardware needed for installation.

Please note: This backbox is roughly 30% louder than the factory item.

Fits cars both with, and without the appearance package.
