Now, to the noticeable differences. I hope you will all know what I am talking about when I mention the cracks on the freeway from one interchange ramp to the other (like the big swooping interchange turns). Before, I did a test to see how fast and how comfortable I was throughout the turn. I noticed that the rear end liked to kick out or jump a little bit when every I hit those (I am lowered on Eibach Sportlines but it was just like this before I had the springs installed) and I could maybe go 80mph before it was a noticeable jump. After the x-brace, I came into the same turn at 80..left the turn at 110+ without a single kick out or jump..it planted the rear end and I could just keep on going. It was awesome..even my brother in the passenger seat noticed a difference so we are also going to go drive his car (same turn because he doesn't have the x-brace and he is also lowered on Eibach Sportlines) and then come back with my car and feel the difference and then I can give a better analogy of what it is like.
