SCCA Time Trials Mazda MX-5

By: Chris 05/28/2021

Owned since new, my 2006 "3rd gen" MX-5 was my daily driver and weekend SCCA Solo (autocross) toy for 8 years. In 2011, I trophied (4th) at the SCCA Solo National Championships in the C Street Prepared class, after leading Day 1. In 2014, I bought a Ford F-150 FX4 3.5L Ecoboost Super Crew as a tow vehicle along with a trailer, and it's been a track-only car since then. I finished on the podium at the SCCA Time Trials Nationals in 2018 and 2019.
