That sounds backwards. You sure it's your camber? You use these camber bolts to increase negative camber, which would make tire wear worse. Not vice versa.
I have tokico hp blues and progress 2" lowering springs and my front tires are wearing on the inside. With that Said would these fix that or should I get and alignment and see if that fixes it? I'm about to buy new tires and don't want to rewin them.
Front/Back: +/- 1.75 degrees of adjustment
as long as it's not more than that you should be able to adjust accordingly
as for alignment charges... firestone charged me an extra $100 to adjust camber bolts with alignment
