here, this is what "civic hatch" said about it, and it makes perfect sense: "the best way to descride camber, toe and caster, is put your hands open infront of you with you plams facing each other. now tilt your thumbs inward or outwards, this is camber. now go back straight, put your finger tips closer or further together keeping your hands straight, so that they point inwards or outwards, this is toe, and if you point you fingers upwards of downwards this is caster.
if you look at the rear of a car and see the top of the tire leaning in or out then that is camber
if you look at the car from above and the front of the tires are pointing in or out then this is toe
if you look at the front steering knuckle and it point forward or to the rear then this is caster, caster isnt adjusted much unless you get into a accident the throws it off."
Personaly, i would think that if you camber was off, the inside of the tires would wear very quickly. if the toe was off, the tires would also wear quickly, but not as uneven. Plus, when do you rreally see toe being off by that much? Just get an anlignment at a shop and they will give you a print out saying what your camber is and they will correct your toe. If you camber is then off, which they can't adjust without a camber kit, go ahead and buy one
