If tire wear is your main concern on a lower car, you have to back out rear camber and toe in. Toe and camber move inversely on a 996, so you need a way to adjust both independently beyond what the factory eccentrics allow. While this is an easy fix, unfortunately not cheap. You need rear adjustable control arms and rear adjustable toe steer links. Get your camber closer to -1 with just a touch of toe in if tire wear is a priority.

 

Bumping this up, looking to correct my tire wear. Mine isn't nearly as exaggerated as vglnte1 has, but it's definitely exaggerated towards the inner edge. I bought my car lowered on H&R springs, the tires on it had decent wear but the tire wear I put on them is heavily favoring the inner shoulders. The car has "a lot" of negative camber, I'd have to get it on an alignment rack to find out

Do you guys think that toe links would be the better choice over dogbones? Would one OR the other provide enough compensation for a street car? I was leaning towards the toe links because I'd rather get rid of the slop there as opposed to camber.

 

Toe links over dog bones hands down, any day of the week and twice on Sunday... You can have 0 camber but if your toe is out of spec you will destroy the tires rather quickly.

 

Perfect, glad I was on the right track. Thanks for the quick response!

I was gonna be pretty irritated if $400 lowering springs required $900 in rear suspension modifications lol
