While you may enjoy spending countless hours experimenting, testing, tuning and making your own parts in the pursuit of suspension perfection on your race car, this tends to be an expensive and time consuming proposition. In fact, it took years for Jesse Prather to perfect a shock and spring package that has proven not only reliable, but one that wins National Championships. At the SCCA National Runoffs in 2014, Matt Reynolds took the win in E Production (and again in 2016 & 2018) and Brian Laughlin finished second in STL – both equipped with Jesse Prather Motorsports AFCO shocks. This same package is available through Mazda Motorsports.

The shock package includes AFCO aluminum threaded-body coilover double-adjustable racing shocks. The shocks have custom valving designed specifically by Jesse Prather for the NA first generation and NB second generation Miata race cars. The AFCO shocks have separate rebound and compression adjustment knobs and bolt on to the stock control arms. The front upper spring perch hole has to be opened slightly on NB Miata cars.

“The beauty of these AFCO shocks is the progressive valving. You can adjust them for any number of different cars and any number of different tire compounds and construction, whether it’s a D.O.T. tire, a slick, radial or bias ply,” stated Prather. Many top contending Solo competitors use this shock package, as well.
