Question bout lowering?????

I plan on going with the eibach pro kit and i am also gettin some 17 by 9.5 zr1's and i am wondering if i will need to get a adjustable panhard bar or if stock will be ok?
thx rob

stock should be ok...clearance wise

i think that amount of drop shifts the axle about 1/4-1/2" to one side. but with the 9.5" rims you shouldn't have much trouble. the hassle comes when trying to install 11s with 315s in the back
