Warmseth, big props for being able to heel-toe in a car. I find that way harder than "heel-toeing" on a bike.
Anyway, other than practice, what helped me get good at it was to just use my plam to match the revs while applying the brake. It kinda keeps things simpler than actually gripping the throttle and any leather glove will be sticky enough to do this. The 2 fingers that I don't use for braking are just there for decoration.
Well, now that I think about it, I do this cause I've got small hands, so maybe if you've got average-big hands you won't have to do this...
Good Luck anyways
