Cooling
Toyota did a good job with the GR Corolla's cooling system but it is still street focused and intended for stock power. If you find yourself pushing the car at sustained high RPM and load you may find the limits of the stock cooling system. You may even feel the car pulling power. To avoid heat soak and keep the your car at peak power consider upgrading the radiator and/or intercooler. Tuned with increased boost pressure keep that power you gained by keeping those intake temps under control.
