Wheelie question

What's the ET of your car? This might sound stoooopid but I do things that are low cost and when my 10.60 car was coming up too quick and unloading the rears, I took the 90/10's off and threw on some 50/50's. After trying limiters, adjusting the ladders, ride height and throwing the kitchen sink at it, I put everything back like it was and tried the 50/50's low and behold, they worked. They were just some spare street shocks hanging on the wall....
