I have 03 sedan with eibach sportline drop, i put the drop on about a year ago. When first installed had a 2 finger gap after settling a year it tucks a little tire now, I had my alignment set when i lowered it and ate all 4 tires on the inside in 6 to 7 months, now ive chewed thru my second set. I know I need camber kit but thought with toe set right would get a little more life out of tires than that. Does this sound right to get about 10k out of a set with neg camber. I am ordering a rear camber kit but the front a little costly. Wondering if my alignment guy was off from the start. I figured Id wear the fronts but not all 4 evenly that fast.

 

Toe has much more effect on tire wear than camber. Maybe if you post your alignment settings we could offer more advice. It seemed that when I lowered my sedan an inch the tires all went toe out, so your car may have done the same when it settled. Any toe out in the front will wear the inside of the tire rapidly. It is probably best for wear to set front toe to max toe in spec. At least that was what the 350Z service bulletin recommends.
