If you can’t use the brakes, use machine gun shifting, or
double-downshift.. if you are using a gear 5 car, quickly double
down-shift to gear 3 and then quickly back up to 5th..all must be
done very quickly..if you are using a 6th gear car, do the same but
only shift down to 4th..for iro, you might have to use third for
some of the turns if you using 6 gear..hope that helps..
