Never used a sequential gearbox, so I'm a bit curious, why wont he push the clutch all the time while switching down? Is he using the engine too to slow down the car?

@MyBoogeryBooger

Actually, it's because sometimes you get "pad knock off" where the brake pads get pushed back by the disc. It means that when you go to brake, the first part of the pedal application does nothing because it's just taking up that slack. Therefore when coming up for a big brake like at Fuji, they'll dab the brake to make sure the pedal will be firm and the pads will be in the correct spot, not a few millimetres from the disc!

whats with 2:25 ay? Pulling the finger!!! hahaha!!!

@MyBoogeryBooger Well that would make sense. Have them primed ready to go.,

[MyBoogeryBooger]

@WiseGuy02 No, um racers do that because it pushes the fluid in the hoses a bit more so they provide more braking power. :)

@jelzin1985 no, he doesn't need to use the clutch to shift down, but most drivers prefer it because it doesn't wear out the straight cut gears.

@izagury Probably checking to see he still has brakes. Don't want to get to the end of the straight and find they've failed at 270kph.

[izagury]

Why he touches the brake with his left foot sometimes??(just touch, not press)

Ecco un bel esempio di come si fanno le cambiate con il sequenziale...ottimo il punta/tacco per tenere alto il motore in scalata...peccato la macchina non sia tra le mie preferite ma al pilota tanto di cappello, very good racer!

@MPI100 Jelzin 1985's point was that it's a sequential gearbox so you don't need a clutch. He's correct. The initial question didn't ask whether there are H pattern gearbox's that can operate in a similar way.
