Myself and 3-4 others at the NSX modified shop have had problems with the Eibach springs. Mine is leaning to the right and the fronts are collapsed. However the car is still drivable. It developed over a period of time. Some others even had problems right when they installed new springs. I have talked to Eibach in person since I live down the street from them and they acknowledged that the car is sitting funny are going to do a test on the springs sometime this week or next week. I've been told to get everyone's names who have been having problems with their springs so that they can pinpoint the problem and fix it. Leave me an e-mail if this applies to you.
