How much are you expecting to pay for your wheel? They come in all types of prices. From $39.00 to $2000.00. My experience with race wheels is you generally get what you pay for. Are you looking for forse feed back?
Thomas-Super Wheels is one of the best you can buy. They are a little pricey, but will last forever.
Act-Labs Forse RS is one of the best forse feed back wheels you can buy. A little bit more reasonable in price.
Of coarse there are the Microsoft and Logitech wheels which come in both forse feed back and non-forse feedback versions. Both are good basic wheels but do not hold up as long or as well as TSW's or Act-Labs.
I am in the middle of building my own homemade race wheel. If I ever get it finished, I will post some pics of it.
Nascar 2002 was just released this week. It is the ultimate and most advanced stock car simulation game available.

Grand Prix Legends is also a great race game.
All the Need for Speed titles are fun.
Dirt Track Racing is ok.
Nascar Heat is not bad, but N4 and N2002 is much better imho.
Edit: I believe this qualifies as general hardware; along with some suggested software to use with the hardware
