The standout point to me is that you need to control your brakes more. You're applying too much/100% pressure on the braking trigger and its causing you to lock up. When you start to brake, you want to be 'progressive' on the brakes by squeezing gently at first, and then when you get further into the braking zone, squeeze more and more until you're slowed down enough for the turn. If the controller starts vibrating when you're braking, its telling you that you're skidding on the track. This costs you time and wears your tyres. Also, you are braking and turning the wheel at the same time due to coming in too fast to the turns. It will definately help you to stay on the racing line more often if you brake first, then turn second. Always easier to speed up through a corner, rather than slowing down. Then when you're ready, start looking into trail braking. This is where you gently release the brakes as you accelerate, but this is for much more advanced drivers. All these things will help you to control the car, and not burn out your tyres from skidding all over the track! Hope this helps!
