Hey Lito, go to my photo gallery and you can see my LS lowered. At the time of the photos, I had 225/45/18 in the front, I now have 235/45/18 (have 245/45/18 rear). It fills in the wheel well better and also a little more gronf clearence.
The V6 and V8 LS use the same struts on the rear, the fronts are based on if you have a V6 or the V8. LS4ME has measured my car and others with the Eibachs and has come up that my car is a little lower the V8 ones. I don't know what it is but I would like to have another Gen2 V6 lower to compare with, but no one around here has one.
