See if you can find OEM Subaru Impreza WRX Pedals/Pedal Covers.
I had an 02 WRX and the pedals have a sporty aluminum and rubber design but it's simple and functional without being some kind of cheesy "fast and the furious" style.
I liked them so much that I found a set of pedal covers to replace the stock, plain rubber on my Nissan.
These are
real pedal covers in that they're a rubber base designed to be stretched around the factory medal pedal platform... NOT the stupid clamp-on stuff you get with aftermarket pedal covers.
the matching dead-pedal is not OEM, it's aftermarket, made of reasonably thick aluminum with rubber inserts for the grippy bits... the black circle at the very bottom and very top are actually plastic fasteners and thats how it attaches to the floorboard in the car... the OEM pedal attaches the same way but it's just cheep plastic.
The clutch and brake pedals are like normal rubber pedal covers but they have a piece of sheet-metal aluminm that's been formed over the top of it, obviously the rubber pedal below has the grippy bits that are designed to stick up through the sheet aluminum.
the gas pedal is actually plastic, the whole pedal is plastic and connected to the arm by a pin. it has sheet aluminum like the brake and clutch but there's no rubber.
these all hold up incredibly well, I had that car for 5 years as a daily driver and aside from the nubs getting warn down a little bit they never fell apart or anything like that... should be good for a lifetime in a home arcade cab.
EDIT: you can buy them here:
