VERY VERY impressed. The car actually has traction now, can't believe it. The whole rear of the car feels like it's tightly attached instead of hanging on rubber bands. And I'm still running with old/tired stock shocks, the new springs/shocks get installed next week. Can't wait!!
There is marginally more road/drivetrain noise than before, but it's barely noticable... like 10% difference. (you'd have to be a freak like me to notice the difference in noise)
