I have a King Cobra clutch and I love it. Its great for street use, however if you plan on any heavy mods in the near future (like before you go through another clutch) I would look more towards a dual friction clutch of some kind. They aren't that much more expensive than the King Cobra, and they can handle a lot more power. Might as well toss it in there now instead of having to pay for another clutch install in the future.
If you just plan on mostly street driving though (or are low on cash), you can't go wrong with the King Cobra, its good for what you pay.
