Understand, I use this as a
substitute for, NOT simulation of, real driving feedback.
After acquiring my ShakeSeat, SRS released
Shake Plus seat+back pad,
which I would probably buy instead, if starting now,
using the back pair for engine and acceleration feedback. As it is,
SimHub engine is tuned to shake bottom sensors only at low revs, e.g. in the pits.
Otherwise, it confounds lateral loading and tire slip sensing.
Thing is, I really don't recall getting much stimulation thru heels in real track cars
and expect it would be distracting.
I moved a well-fitting Momo seat from car to car and could mostly relax my torso while strapped in tightly, so plenty of sensation thru back, bottom and thighs.
Heel-and-toe position with right foot and left foot either on dead pedal
or over clutch. Responsive brake pedal rumble is wanted to help judge brake lockup,
at least until I cease resisting the seduction of G-Belt.
Practically, in order to shake heels, a heel plate should be
isolated from chassis and/or whatever locates pedals relative to seat.
Otherwise, with a pedal plate e.g. on rubber isolators,
throttle would also deflect with brake pressure, confounding heel-and-toe.
Perhaps that is a non-issue for left foot brakers using paddle or sequential shifters.
At any rate, some folks use
SRS ShakePedal as an active heel rest.
Again, by directly stimulating heels, those exciters do not need much power.
