After installing the new coilovers on my 1g i had some pretty bad negative rear camber. Jovan brought it to my attention that there is a fairly easy and free fix for this
All of the pics are of the passenger side and are taken from the rear of the car
1. Jack up the rear of the car and remove the wheels and take a look at the rear suspension you should see something like this.
2.remove the bolt circled in red from the first picture and move the arm up and out of the way (I tied it off to keep it from getting in the way) I used a jack to take some of the pressure off the bolt to make it easier to get out
3. now all you need to do is take a die grinder and cut back the holes (shown in red) depending on how much your camber is off you may have to cut them back a fair bit, but be careful not to go too far I didn't cut out enough on the first try so i had to redo it, also try and keep ur cut straight and level
here is how much i cut out on the first go (note it wasn't enough to fix my camber completely but it did help)
sorry the pic is a little out of focus but you get the idea
5. reassemble everything and you're all set
PS do this at your own risk, I'm not responsible for any damage you may inflict on your car or yourself blah blah blah
