Toyo Tire U.S.A. Corp.’s (Toyo Tires) Proxes RR DOT competition tire has been selected as the specified tire for the newly-announced Mazda Spec MX-5 Challenge Racing Series, and Toyo Tires is to be named the presenting partner.
This new series creates a single spec applying to multiple sanctioning bodies including NASA (National Auto Sport Association) and the SCCA (Sports Car Club of America). The symmetric, two-groove Proxes RR comes off-the-shelf with a 4/32nds tread depth.
The series targets the 2006-2015 Mazda MX-5 (the NC-generation Miata). Mazda Motorsports offers “kits” in various forms, whether converting an OE street car or converting a race car already built to meet an existing race class for a specific sanctioning body.
The Spec MX-5 Challenge presented by Toyo Tires will have a series of marquee events run in coordination with both NASA and SCCA. The preliminary 2020 racing schedule and event structure will lead to both regional and overall championships. Other opportunities to compete in the Spec MX-5 Challenge include series such as the World Racing League – GP3; ChampCar Endurance Series – EC; and American Endurance Racing.
