Rear end spins out to the left.

At the risk of dragging a thread back on topic.

I gather from your posts that this car is used on the strip, street, and track. With the multiple uses of the car (and even without), making changes without first knowing exactly where you are starting from is not a wise move. Your first step needs to be a complete four wheel alignment so that you can be confident where each wheel is located, and where it is pointed. This should include a corner weighting, pinion angle, and verifying shock valving on a shock dyno. The alignment figures you use are irrelevant as they are only a baseline. Once you know where you are starting, you need to mark your components and establish a setup log to record the effect of every change you make.

Unless you complete the above, not a person on this earth can accurately help you with setup advice. Someone may get lucky, but it will be luck.

Now, back to the regularly scheduled sarcasm.
