First Time Drag Racing Video

This is where I will show my ignorance. I always thought you wanted the rear of your car to squat as that means you got proper weight transfer to the rear.
If you own a Chevy, then yes.

Would you please explain to me why you want the body to separate from the tire? The more I think about it and the more I watch the video of that challenger, what you said sort of makes sense but would I think I may be missing something. Thanks!
Rear the MoPar Chassis book.

A MoPar on leaf springs should do what that Challenger did.

You might want to try less air in the tires. S/S springs or cal trac set up. Drag shocks in the rear. Frame connectors.
