depending on if the throttle is top or bottom hinged makes a huge difference aswell.
Personally I use the ball of foot on bottom hinged brake, and heel on a top hinged throttle. This requires greater heel movement which provides better throttle control. This is in all the
Sakers that I have driven. Its also the same method that I've seen by any GT racer in NZ/Aus/Europe whener the footcam has been shown.
Couple of
V8 Supercar foot cam vids.
Greg Murphy - Single seater style, this is using a "dogbox" H-pattern with clutch, no auto-blip/cut or anything either.. there IS a clutch in there still
Mark Skaife - This is more of the classic heel-toe imho, he does however have one thing different, he usually downshifts 2 gears at once for better braking control in the hard braking areas.
Neil Crompton - The most classic of the three (imho)
In the V8 Supercars clips above you will notice the brake tap with the left foot before hard braking, this is due to having floating calipers, and as such suffer from pad knock-back causing a longer pedal than normal. The small brake tap is to bring the pads into place (minimum gap) before hard braking. Pretty much every V8 Supercar driver develops this habit.
When racing online, I use the Greg Murphy style, when driving a Saker, I use the Neil Crompton style (except for flat shifting).
My road car has ridiculously powerful boosted brakes, so i cant heel-toe in it without locking up
