$3000 LMAO, that's a huge-azz waste of money, when you could spend that on say JRSC or Turbo, or whole engine rebuild. And yes, I know someone who had them installed on his 5th gen, a sponsor hooked him up with them, and they do not hold up under normal driving. If you are planning on using them on a daily driver, they will most probaly break under normal "wear and tear" stress.
