For the past two plus seasons, Mazda Motorsports and Ron Bauer have been developing together a 2016+ ND (4th generation) MX-5 Miata for autocross. The pairing started early on at the 2015 National Championships with Ron driving a car as an exhibition in Street Touring R (STR) along with fellow Mazda drivers, Erik Strelnieks and Tara Johns.
After two seasons of developing the car for C Street (CS) and STR, Ron is now moving to the next category, Street Prepared. Unlike most of the previous generations of Miata, the Sports Car Club of America (SCCA) has classed the ND in B Street Prepared (BSP), rather than C Street Prepared (CSP).
Street Prepared has been around for much longer than Street Touring, but the rules have many similarities. The good news here is that it allows us to take what we learned in STR, and build on it. Key differences include the ability to run E85, flare and/or cut fenders, update/backdate (we’ll cover this more in a later article,) clutch changes, and the big one, tires.
“Street Prepared was the obvious next step in developing this platform. Coming from Prepared class in my previous NC MX-5 Miata, it’s going to be awesome to get back on actual race tires. Hoosier makes incredible tires and I’m looking forward to working with them also on this project. We’re planning to test out their new for this year 295/35/15 tire using 949 Racing’s new 15×12 6UL wheels,” says Ron.
“I have already added a number of parts from the Mazda Motorsports catalog along with other upgrades. Early season testing has been limited, but looks promising. Of course, the only way to see for sure is to travel to National level events and compete directly with the benchmarks,” he adds.
