i have a civic lx and would like to get 17s i need to know if i need a camber kit plus the car is lower 2 inches what size tires should i get

You would need 17x7" with 42-44mm offset and 205/40x17" tires.

Personally I don't think you need a camber kit with a drop 2" or less.

it shouldnt be a big camber diffrence with a 2" drop. but, if you are the perfectionist, and you want to save money, for what its worth, try puting washers to adjust the rear camber, instead of buying the rear camber kit.
