Camber problems

OK i need some clarification on camber kits. Im planning on getting the H&R sports that say they drop 1.5-2 inches. Some say that a camber kit is not needed and will have no effect and some have said it is cridical to your tires. So i figure it wont hurt to just get some, right? Now i looked around and seen ingalls has two type; ball joint and mount kits, whats the diffenrence or better of the two.

put the springs on, let them settle, and if the camber is within reason dont worry about it. What do you mean by "mount kit"? controle arm?

i have a camber kit, but i dont really like it much, im probably gonna sell it when i sell my coilovers, its unused by the way.

Im not sure, but it sounds like one uses a new control arm that has a upper ball joint that is adjustable. The other one probably adjusts where the upper controll arm mounts to the body. That is the type I have and it works fine. Cheaper than new tires every 6 months
