Improvements to the car physics simulation model and assist settings have been made with Gran Turismo 7's Update 1.31. Please see below for details.

■ Suspension Physics
　・The calculations model of the suspension geometry has been adjusted. This will improve stability of the car orientation during braking, and traction during acceleration.
　・The damping characteristics of the suspensions has also been adjusted. This will improve stability of the car when driving over bumps and curbs.

■ Tire Physics
　・ Stability when turning in low speed corners and over curbing has been improved.
　・Tire heating and wear model have been optimized.
　・The aquaplaning effect on wet surfaces has also been optimized.

■ Aerodynamics
　・The aerodynamics data for formula cars has been updated.
　・The downforce and air resistance in relation to the vehicle ride height has been optimized.

■ Anti-Lag System
　・A limiter to prevent the engine RPM from rising too much while stopped has been implemented.

■ Car Initial Settings
　・We changed the initial settings of the suspension and aerodynamics on race cars and certain road cars.
　・The Performance Points (PP) of various cars in the game have been adjusted.

■ Wireless Controller Handling (Steering)
　・The handling of cars have been improved by adjusting the steering algorithm when using the controller's stick or directional buttons.

■ Wireless Controller Handling (Force feedback)
　・The handling of cars while steering and information gained from the force feedback should now be improved by adjusting the force feedback algorithm.

■ Assist Settings
　・We changed some of the default settings for the Assist Presets in the Assist Settings as follows:
　　INTERMEDIATE
　　　Countersteering Assistance: changed from Strong to Weak
　　　Traction Control: changed from 5 to 3
　　EXPERT
　　　Countersteering Assistance: changed from Strong to Off

　　If "Intermediate" or "Expert" was selected prior to Update 1.31, the settings will not be overwritten, but the Assist Preset will change to "Custom" instead.

　・Controls for the Traction Control (TCS) have been adjusted. The amount of intervention when set to "1" has been reduced, and increased when set to "5."
　・Controls for the ABS (Antilock Brakes System) have been adjusted. This has improved stability under full braking situations.
　・Controls for the Active Stability Management have been adjusted. The amount of intervention when oversteering has been increased to improve stability.
　・Controls for the Countersteering Assistance have been adjusted. The amount of intervention while oversteering has been reduced, now making the amount of orientation change milder.


Thank you for your loyal support, and we hope you continue to enjoy Gran Turismo 7!
