i know i cant really quote anything online, and i know i said mazda itself has won many titles, but i was actually refurring to the rx7.
Mazda began racing RX-7s in the IMSA GTU series in 1979. That first year, RX-7s placed first and second at the 24 Hours of Daytona, and claimed the GTU series championship. The car continued winning, claiming the GTU championship seven years in a row. The RX-7 took the GTO championship ten years in a row from 1982. The RX-7 has won more IMSA races than any other car model.In the USA SCCA competition RX7s were raced with great success by Don Kearney in the NE Division and John Finger in the SE Division.
