After delivering more than 50 GR Supra GT4 race cars to teams and with more than 50 class race wins in major Championships since its launch in 2020, Toyota Gaza Racing has now released details of the EVO version of the Supra, set for customer deliveries for the 2023 season.
Development engineers focused their efforts on three key areas: brakes, handling and engine.
With an improved brake system design, new ABS settings, updated KW damper technology and updated anti-roll bar specification, the GR Supra GT4 EVO will deliver improved handling and higher cornering speeds.
The EVO also boasts increased power and an optimised torque curve of the 3.0-litre, six-cylinder, turbocharged engine, which also benefits from more effective cooling.
The GR Supra GT4 EVO will make its competitive debut in January 2023 at the 24 Hours of Daytona, the first round of the IMSA Michelin Pilot Challenge season.
Orders for the GR Supra GT4 EVO will be taken from October 28 2022 and an upgrade kit will be available to existing GR Supra GT4 customers.
