Dude, you have nobody to blame but yourself. Get a life and stop insulting people over the internet. If you want to learn, use the search button, and learn the basics. We'd all be happier if you left rx-7s to people who can handle sports cars and DO actually buy that mustang.

 

OK, I think that's quite enough of this thread.

Fair enough. Please read up some more so that you at least have some base knowledge on the subject. These are some good links:

If your friend has a 600hp car, then he will probably will be able to help you better than the internet peanut gallery.
