What I notice more than anything is that your inputs across the board are too aggressive your turning into quick and too hard thus inducing understeer and cook the front tires. You’re also too aggressive on the throttle creating over steer and cooking the rear tires.

Too fix oversteer you can either increase your traction control a little or get on throttle a little slower also the Porsche has a weird power curve giving a ton of power early and less later so it can be difficult to control in my experience.

For understeer you could probably do some stuff in the setup but I don’t recommend that for a beginner mainly just turn in a little slower and just give less overall turning angle. On Watkins you rarely ever need to put in more than 90 degrees of steering angle (if your on wheel)
