Judging from your trap speed you probably could drop more than the .2 my guess is closer to a second. The 60' foot time suggests you are having traction issues. I think if you replaced the bushings in the rear with either Nismo bushings or get the SPL parts, the suspension would have more linear control and stability. You will definitely need one or the other when you put the T04E on.
The install looks really good by the way.
