One of the great things about Spec Miata is its simplicity, and it starts with the suspension system.
You don’t need to be an expert at spring or shock rates to get the right suspension system. You just sign on with Mazdaspeed Motorsports Development and you order a kit. One part number covers all the suspension bits you need to race in the class.
True, the early cars need the shock hats found on later models and everyone benefits from adjustable sway bar end-link kits, but the process couldn’t be simpler. However, don’t let the simplicity lull you into thinking it’s unsophisticated. The Miata is a brilliant little car, which is something you learn the first time you drive one, and come to appreciate on a deeper level after you have turned a wrench or two on it.
All the right ingredients are present and all components are fairly easy to get to. Independent rear suspension with coil-over shocks for planted cornering. Double wishbone suspension front and rear for camber profiles superior to strut cars. And let’s not forget curb weight. In Spec Miata trim, the car weighs in naturally at about 2,100 pounds.
Those parts add up to something greater than their sum, and they capitalize on an arguably rudimentary suspension upgrade. Installation is pretty easy, too, but after having built two of these cars, we’ve learned a thing or two along the way. If you are planning to build a Spec Miata, we hope this helps.
