Dont know if this has been mentioned before, but if you go to the skidpad now and drive up to the gate it resets the car and you can even "drive" through the gate. Pic attached.
quick description, smash through the bollards, careful not to go through the building, drive around the outside of the building, onto the access road, then "sneak" onto the section that is not drawn properly at slow speed, you will fall down, but fall at an angle, when reset you will be on the grass, drive around the grass up to the said gate, smash into the gate as speed and fly through into the skid pad area.
i do realise the above massive paragraph will not help you in the slightest
and by the time you do all this the car normal has completely spackerd suspension on all 4 corners
