oh no. trust me. u're surpassing nothing. u're not putting all
emphasis on skills training.
besides, i don't think u know what a hard time and an easy time in
racing skills training is. u start in a sports car, i can tell u
you won't be progressing very far. the power flatters your lap
times on the straights, and masks any cornering mistakes. As a
result, u're not learning as much as u should, not being forced to
think as much as u should.
If u want to progress fast, my challenge to u is to start training
in something that doesn't have a lot of power(so no advantage on
the straights), is very lightweight(so u have to make up all your
time in the corners), RWD(emphasis on throttle control), no rear
differential(more emphasis on throttle control), only rear
brakes(easy to lock up and spin, hence emphasis on braking control)
very short wheelbased(thus prone to snapping into a spin easily,
more emphasis both on braking and throttle control).
u start training in something like this, u will have a harder time
than u ever will in a skyline, i promise u, and u will improve MUCH
faster too.
