try sitting a little bit on your left hip, not so much that your uncomfortable, but enough so that you dont have to twist your knee/ankle that much untill you get the flexibility & coordination down.
I found the gt-s pedals a bit more difficult to heel toe (at first) due to the gas pedal height not being the same height as the brake pedal.
also if you ever need to use a 1st gear turn and have to gear down under hard breaking heel toe is the only way to get it in because you have to rev match to get it in gear in 1st at higher rpms, very helpful on auto x
