There both good they both drop over 2 inches in the front and the back. But I've heard about eibachs sagging in about 2 years. Havent heard anything bad about intrax except you take a risk when you put them on 9C1's cause of the rear shocks being longer in length. And they can fall out if the tires come off the ground. Only in the rear though. But dont listen to just me wait till other people reply Im just going by what was said on the boards never from own personal experience.
