Should I have an alloy foot rest?

I've got a FF 200 with the cup chassis, but I don't have a metal foot rest next to the clutch, just carpet.

Should my car have one or is it an extra I have to get hold of myself?

If anyone has anywhere I can get one that would be great.
 
As far as I am aware its an accessory that does not come with the car, was the case with the 197 anyway.
