I took the car for a spin, yesterday. I was a little concerned about adding ride harshness from these. Much to my surprise it was not an issue. I think the added ride height helped with the slight bump steer I was getting. I also dialed out some of the neg. camber the car had and gave it the most detailed toe alignment I could muster with strings and jack stands. It feels really good right now. The car is straight as an arrow and the steering is nice and light. It could use a little more neg. camber to get that bite on corner entry for the track, but at the moment it perfect for the street. I'm not sure I'll mess with it any further.
I definitely recommend you guys do this mod. You can definitely get your camber dialed with precision using these. I'm very happy with them.
