I just installed my eibach sportlines, do i need a camber kit? Can i live without it?

you can live with out it, but it something you should look into later on down the road, but then again the sportline drops pretty low so in my opinion I would get camber kits, in general i would get it no matter what anyways.

yep! you are going to need one sooner or later....

fosho. get a rear one, there pretty inexpensive.

Definitely get the rears

As for the fronts I'd guess youll need it...get an alignment done to see how far off spec you are and judge from that
