Rear axle feels like it's twisting!!!
 

ok when i shift and then get on the gas right away......i feel like the rear of the car go a different way then the front half of the car would be going!!!!!!is maybe a rear axle mount broke or something or what?????

Sorry, but the axles break when they twist. You lose traction for a sec when you let out the clutch, right? It sounds like youre car is just spinning the tires a little and the back is stepping out.

What model and mods do you have on your car?

If you have the spare time, you might want to jack the rear up and see if the lateral links have excess play. Lateral link is a bar running b/t the hub carrier and fwd. Its I think about two feet long. Has ball joints on the ends that can go bad or be installed wrong. Take the fwd and aft end of the tire and pull with one hand and push with the other. Should have squat in the way of play.
EDIT: You can go to this thread https://www.rx7club.com/forum/showth...threadid=51998 and MIKE L has a schematic posted there and you can see the lateral links on the left and right sides running from the hub carriers to the subframe in a lateral fashion. If they are real sloppy the rear wheels will toe out and self steer.
