When i start backing off gas the back of car steps out . Rear end is straight and square in car brakes not hanging . It will do it if going down straightaway and half to get out of gas its almost like some hit me in lr thats how quick it happens. Its crazy feeling

broke axle? rear end shifting as it relaxes? check rear end control arms for bad bushings, bad heim ends whatever. Don't know your setup.

have you switched to a direct drive trany like a bert or brinn from a conventional flywheel set up? reason i ask is a person i was helping with a nesmith street stock switched to a bert when the rules allowed it and the engine would brake the rear tires loose when dumping the throttle, once he learned how to ease off the throttle he got faster and faster....

Chassis bind or locked/ sticking shock will give that feeling.

Check to see if axke stripped in spool or drive plate. All left rear will make act like that also.

Again are bushings in control arms or rear end good? What do you have for trail or lead? Where do you have the lower control arms bolted on rear end mounts i.e.: all the was up or down on the left or right.I assume that this is same car as last year and weight is in the same place? Or new car? Are you sure you have enough rear % bite seems to be about right compared to a lot of people I know that run metric cars.

Drive shaft bottoming out in the trans? Just a thought.
