Mazda MX-5 is a great sports car, but it always suffered from the lack of enough power. Some say it shouldn’t have big power, because effortless performance will take all the fun out of driving the MX-5. That might be true, but there’s no denying the car’s straight-line performance needs a bit of tweaking. Luckily, BBR-Cosworth supercharger kit is at hand to address that problem.
