clutchless up shifting, heel and toe double declutch down

Demonstration performed in a group N Impreza rally car with dog-engagement gearbox - do not attempt cluchless upshifts in your road car it’ll just wear out the synchros. Here I am cluchless up shifting (except first to second). On the downshift I am using a heel and toe/double declutch technique to ease the engagement of the dogs.
