Hey Guys...I recently installed a Swarr Bar on my 08 GT500...(547 rwhp pulls)I do get less wheel spin and got no hop on hard launches (did install Steeda Billett LCA's long ago which took out most hop but is even better now)... the car launches straighter and the rear just feels tighter...just thought I would pass my observations along.

 

I found a major improvement with the Steeda upper and lowers too!
