Why is the clutch pedal so abnormally thin on the Lexus GT3 car in IMSA? Because they wanted the widest brake pedal possible.

“That’s something I introduced when I came to the team,” Lexus brand ambassador and former Vasser Sullivan Racing driver Townsend Bell says. “[It’s] because I wanted the fattest brake pedal face. We couldn’t move the pedal arms. …

I guess the clutch just doesn't take much effort, which is to be expected. I would have thought leaving the left half of the pedal face would have helped, but if it is not needed and doesn't help, it is just extra weight.

Left foot brakers and sequential gearboxes are shrinking our clutch pedals!

Similar setup is in WRC cars.

 

Can't find a video of it, but I think it was a Grand Am GT RX-8 that needed the clutch pedal with an EMCO sequential box. The driver still had to heel-toe downshift.
