anyone adjusted the pedal height for easier heel toe shifting? can this be done?

I am interested in the answer as well

I don't have a problem...
 

Just cheat your foot over to the right side of the brake and rotate/bend your foot to blip the throttle with the lower right side of your foot. The shoe you are wearing will affect the ease of the procedure. I wear size 13s, so you who are small of feet may have a different story.

I can tell you that on the track the process does make for gentler, more balanced downshifts and smoother transitions.

Doing a STFA, and came across this as I plan to do this.
 

I had a spacer on my B5 S4 and plan on trying something similar to space up the throttle a bit. I had it setup under the pedal so it still looks and feels like factory.
