My car is basically slam with no camber kits. In the pass, technicians usually set my toes to factory specs, and it seem to do the job with wearing evenly, but recently i lowered my car MORE and the front was wearing fast on the inside and rear was doing OK. Yesterday a tech that aligns nothing but lowered/slammed cars and high end model cars suggested that my toes should not be at factory specs due to no camber kits. He suggested a spec that would wear my tire out evenly and not the insides first, but without a camber kit he said it would wear out faster.

My question is... are the specs suppose to be adjusted (on lowered cars) per factory specs without camber kits?

here are the results in what he did.

BEFORE:

Left Front:
Camber - (-2.1˚)
Caster - (3.6˚)
Toe - (0.04˚)

Right Front:
Camber - (-2.1˚)
Caster - (3.6 ˚)
Toe - ( 1.01˚)

Left Rear:
Camber (-3.2˚)
Toe ( 0.36 ˚)

Right Rear:
Camber ( -2.9˚)
Toe (0.40˚)


CURRENT:

Left Front:
Camber - (-2.1˚)
Caster - (3.3˚)
Toe - (0.22˚)

Right Front:
Camber - (-2.1˚)
Caster - (3.9˚)
Toe - (0.23˚)


Left Rear:
Camber: (-3.2˚)
Toe: (0.36˚)

Right Rear:
Camber: ( -2.9˚)
Toe: (0.42˚)

 

By looks of it, only thing that he did was even out your toe in the front.. But my guess is that you will still wear out your front inner's faster.

in a simpler term, when you increase your camber, you are putting more pressure on the inside of the tires. So, naturally, you inner tires will wear out faster.. and combine with more toe (which helps with your car going straight by tires fighting each other) your inner tires will wear even faster.

Alignment is also personal preference... changing it will make the car drive totally different. Also, I try to find the best machine in your city. Alignment is a precision thing and cheap mis-calibrated machine could also cause to mis dial in.

Usually alignment shouldn't change much and also for daily driven car, not necessary to get it done every year unless you see clear signs of tire wear. Like I preach to other people, inspecting and measuring tread depth regularly will best determine if you need alignment or have any issues with the tires or suspension.

Hope this helps..
