Just FYI: the stock pedals are fully adjustable and if they are uneven then the stop in the back of the pedal has just been kicked at an angle. It is easy to place them in a better position and level them out...
That said, if you are just after a different pedal altogether then there are several that we have used.
As Lane mentioned individual Tilton pedals are a possibility, as are individual Wilwood pedals. Wildwood also make some pedal sets that can be fit to the car.
Any of these will generally require a change in the master cylinder, some of them require running dual masters on the brakes with a balance bar. They are all going to require a hydraulic clutch.
I have fit the Fibersteel pedals into a Speedster, and it wasn't that hard. Unless you are just after the look of the Fibersteel pedals then I'd stick with Tilton or Wilwood. The build quality of the Tilton and Wilwood pedals is just much better than the Fibersteel ones.
You can also do direct VW replacements from places like Pedalwerks. Scott builds a very nice pedal set, and will make them to your specs, plus add spacing if you'd like the clutch father tot he left or whatever...
