I will be ordering a lowering kit for my 3 very soon. I am debating on the Eibach Pro Kit or Sportline Kit. I am afraid the Pro Kit won't give the look I am looking for, but the Sportline might be too much. Either way, I know I am going to need a camber kit. Do I just need to order the rear camber kit or both front and back?

Also, if anyone knows where I can get some instructions to do an R8 LED conversion in my headlights lights, if anyone knows, please let me know.

 

This is Basically the Pro Kit on mine, repackaged for MazdaSpeed

The Camber kit is for the rear only, the front drops Straight down, but the Caster will need to be adjusted.
To me the Sportline would have been way to low for any wider tire and wheel combo, and mine was done for handling as well as looks.
As you can see, I am running right out to the lip on the wheels
