Neil after looking at your petals again the gas might be better if you moved it over to the right for more room, since you are not going to be ' heeling & toeing this beauty ' they don't need to be this close together
And maybe have the toe pads all at the same place so it is easer to slide your right foot over if needed, you sure don't want your right foot hitting the side of the brake petal just on top where it counts
Do you have a throttle stop on the petal as I don't see one, very important to help keep the throttle from binding - sticking - going over center etc even bending the fuel injection linkage
