Alright here it goes
I bought a Cusco rear strut bar a few weeks ago and installed it. After I installed it I noticed that when I would floor it in first and then shift hard to second and third there would be a loud bang like the suspension bottoming out coming from the rear end of the car.

Lets just say it wasn't something I liked to hear every time I tackled an on ramp. So I thought it might be the strut bar so I removed it and the "loud bang" stopped. Any thoughts on why this would happen?
