Direct Clutch and their “Sir20B” Mazda RX-7 returned to Lakeside International Raceway in Kurwongbah, QLD, Australia for Rotary Revival 2026. The RX-7 is powered by a turbocharged 2.0 L 20B three-rotor with different boost levels. Behind that is a Holinger six-speed sequential transmission with a Direct Clutch Services 8-inch billet twin-place clutch. The rest of the drivetrain uses a Driveshaft Shop carbon fiber driveshaft and a Cusco 1.5 way limited-slip differential. Watch eight laps of the 66 lap race from the view of the front bumper in the video below.
