I got brand new hankook v12 for my g35 lowered on bc coilovers with ichiba rear camber kit and sadly, lasted only ~9000 miles. Flip once after 6000k miles. I didn't install the toe bolt so maybe that is the problem? This can't be normal though! Here are my alignment specs:

Got one alignment when i first installed the tires.

Front: Camber L(-2.3), R(-2.7)
Toe L(.05), R(.02)
Rear: Camber L(-2.8), R(-2.7)
Toe L(.13), R(.14)

The toe is in the Min. Max. specification range. Would you advise me to install them? or is it normal to go through tires if you are running ~-2.8 camber. Thank You in advance!
