I'm wondering if you change the camber on the camber plates that come on the Cattman coilovers, will it change the camber drastically? enough to screw up your tires? Since my Cattman camber plates came with no numbers or lines on it, can you just eyeball it in the middle and will that be good enuf? or does it have to be exact?

 

Just take it to a reputable alignment shop preferrably the ones the has experience aligning lowered vehicles. They usually offer some type of warranty just incase it feels/drives different after the alignment. They will check it again for free.
