Car goes sideways?

When ever I leave a light and break traction my car wants to go sideways. Usually it grabs until the rpm's get under him and then it's tries to walk into the other lane. (just the rear tires) I have to let up to avoid a serious fishtail and loss of control.

Would the suregrip clutches cause this? It almost seems like one side is grabbing more than the other. I'm pretty sure the car is straight and I don't think I have any alignment issues.

I don't think the suregrip is the problem. My 67 GTX does this when I "break traction" and wants to skate in the other lane. I just dial it back and check the looks on their faces when you drive by!!! Could be any number of factors, but I would say it's all external, as my car doesn't do it every time. I would blame road conditions. In case you get a ticket for "losing traction", don't go with the.... "those spectators egged me on, and they dumped cooler water on the road and I "lost traction"... Didn't work for me and probably won't work for you either!!! Good luck, Geof
