WRC 7 ps4 thrustmaster t300 settings read description for instruction to correct wheel settings.
Plug t300 into pc or laptop. Go to control panel. Click devices and printers. Ensure t300 is in ps3 mode. Right click on the steering wheel icon. Select game controller settings then properties. Update device. Change wheel lock to value that the display shows is 0% and 100 % when you turn wheel fully left and right. My wheel is set to 1020 and this removes wheel deadzone. Next check bottom box for pedals. At the tab at top left Select the 3rd tab from left or right tab. Next increase forcefeedback strength to 100. Put boost on for constant and spring. At the bottom Select 94 for wheel centering and then check the bottom dot to enable game to have control of changing this. In other words allow the software to control the hardware but 94 value will be the value the game works with to make its calculations about wheel centering forces. This value most accurately simulates a road car on my t300. Not every wheel is identical because it Isn't possible but they should be almost the same.
