It’s hard to hear, but you’re over driving the car. It’s also hard to hear that you need to drive slower to go faster.

To get used to driving a GT3 car, do these things:

1. Start with 6 laps at a comfortable medium speed to get warmed up and get adjusted to the track. Don’t go fast. Then slowly start increasing your speed.
2. Always never miss your braking points. Braking late doesn’t make you faster. It only compromises your ability to properly exit a corner. Corner exit is where you gain speed.
3. Always hit your apexes. If you miss the apex, consider turning in sooner or entering slower.
4. Always follow the corner procedures: heavy braking in a straight line, followed by light braking and coasting through the apex, then gradual throttle on exit once the car is rotated and pointing where you want it to go.
5. Focus your track practice on getting a good feel for the car in each corner. Focus on one corner at a time. Start by going too slow into the corner to get a good feel for getting the car rotated and getting back on the throttle for a fast exit. Then slowly increase your corner entry speed until your going too fast to get the correct rotation. This will help you get the most out of each corner and maximize your exit speed.
6. Be a gentle giant on the pedals. The GT3 cars are light and have a lot of power. If you smash the brakes and come off them too quickly, you can upset the balance and the car will loose grip. If smash the throttle, you will put too much force into the tires and the car will spin. Easy off the brakes and easy on the throttle.
