Is it bad form for my heel to slide when using the clutch? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Now, idk if i can equate the accelration of the ball of your foot towards the clutch pedal to the time it takes to disengage the clutch...id need more time to set that up lol.

Who are you lmao

Yes I'll give you the rice noodle😘

No human endeavour can be deemed real science if it does not make use of mathematical demonstration.
-Leonardo da Vinci

Now, the reason your foot is sliding forward depends on number of reason, like pedal ratio, size of your feet, surface friction of your shoe sole, floor mat, etc.

C= 3.146((D/(D-d))^2)((D+d)/(D-d)-2/ln(D/d))
Fn= (4ECeX)(h-X)(h-(X/2)+e^2))/((1-v^2)D^2)

Fn= Axial Compression Force
D=Your shoe size (length)
d=Your shoe size (width)
C= Coefficient of friction of surface (floor mat)
E= Elasticity module of the metal (clutch pedal)
e= Pedal Ratio
v= Poisson Coefficient
X= Clutch Pedal Travel

Now, if C is more than Fn, its ok for your feet to slide, else we got a problem.

Throw the floor mat away and just use the base carpet.

I was going to comment on this subject but got lost in the math, got my **** stuck on the clutch pedal.

Oh god I hate it when that happens. Better then under the brake pedal though I will tell ya.
