general rules for my quick runs:

1. Car. I have repeatedly noticed that only 2 cars are needed for quickly passing levels these cars are lunar rover and grim rods. grim rods are slower than lunar rover ,but have better handling. Each turn must be skidded, this is done simply by pressing the turn button + single pressing the brake (I noticed that with a skid the race is always faster)
2. Driver. There are 2 quick drivers El zippo iand Roxy roller. it is these 2 drivers that have maximum speed when using superpower + have protection against bat missiles.
3. some levels ( shark harbor, spooky shores , crab cove , fiesta village) must be started with a delay at the start. This is done by pressing the brake at the start. This is necessary to obtain nitro in the amount of 3-2 pieces, this will help to improve the running time by 3-2 seconds. (This method is not obtained the first time, usually you have to restart 3-4 times to get nitro)

4.the use of glitches. I know only 4 levels, misty marsh, paradise beach, dino jungle, death bat alley. the most difficult glitch is at the dino jungle level, its execution depends on successfully getting into a certain frame, (I managed to use this glitch only once).

glitch at the paradise beach level - its execution is in a u-turn at the start of the race, while it is necessary to touch the house, for more details you will see in the video.

a glitch at the level of death bat alley is a ski jump while reducing the track. you need to jump exactly as shown in the video, this will reduce the race time.

a glitch at the misty marsh level is the easiest glitch, it is done as shown in the video

5 Use of short cuts. there are short roads at each level, training to complete the race perfectly will help you finish the race faster in 3-5 seconds

minor roadside aids:

shark hardor - the main thing is to perfectly follow the short path and perfectly perform the cut at the last turn (the easiest way is on the grim rod). use superpower on the last lap on a long straight

crab cove- ideally without dropping the speed to pass the bumps, you need to do this carefully, improper passage of the bumps affects the speed of the race. the use of superpowers on the last lap on a straight line

dino jungle - the most important thing is to perfectly execute a short path through a body of water

fiesta village - ideally perform a short way through the tunnel, use superpower on the last lap after entering the tunnel

spooky shores - get nitro at the beginning and use superpower on the last lap on a long straight line

Red planet -use the big jump in the last lap using superpowers
