Ok here's the way i run TT1 with no assists
As soon as you cross the start line drop from 5th to 4th gear redline it until you get to about 207kmh , then up to 5th again also making sure your gently steering the car towards the rumble before turn 1 before you hit the rumble you should be 2 wheels on and 2 wheels off then brake and drop to 3rd to take the 1st bend flat out (the line will be noticed when you hit it right for the 1st time ) keeping the wheels straight and the car should ride all 3 rumbles situated on turn 1 , leaving the 3rd rumble heading to turn 2 you should redline the car to 163kmh before gearing up to 4th and taking the right left before t1 with the car again using both rumbles (a good T1 if all has gone well should be average 20.7 region if not lower )
Power through the T1 and gear up to 5th when it redlines (you'll only be in 5th for a second at the most ) make sure the car is to the left of the track to take the turn into the tunnel , drop early with brake from 5th to 3rd and keep a nice slide to mount the right hand rumble going into the tunnel ( if braking point before tunnel was precise it should naturally hit the rumble and carry you through with the wheels straight and no skid ...
Stay in 3rd as your heading towards the long sweeping left and get a line which looks like your going off in a straight line and as you get a nice point to mount the rumble just take your thumb off the x button while turning left onto the rumble and get the wheels to grip it without spinning you by tapping the accelerator to run you round the rumble , you'll know when your clear and back onto full power and you should naturally power onto the rumble before T2 gearing up to 4th as you reach 163kmh again crossing T2 hopefully in the 48.0- 48.2 region .
Next section is by far the make or break point YOU NEED TO RIDE ALL THE RUMBLES AGAIN going fairly far onto the 1st one on the left hand side then flick it onto the rumble on the right after negotiating the first correctly power until your wheels are straight then hit the brakes but not full on ! dropping through the gears in a smooth rythm the car should be swinging into the bend going into the tunnel , always making sure your car isn't being flicked erratically you should be making tiny touches on the steering to get your car going onto the rumble inside the tunnel with the car facing straight forward , redline it again but not to much or you'll lose the acceleration !...
...Gear up nicely and you can take on the following rumbles taking you up the hill and onto the final straight with nice speed always trying to keep the wheels in a straight line , heading towards the last dash you should gear up to 4th at 163kmh again for the final time and stay in 4th redline all the way to the the end of your lap
Hope this helps Pedro
find this rythm and you'll be in the 1.20.s before you know it 👍
