My undertanding if you use spring you have to get camber kit for front and rear. But, for coilover is already included?.......i just want to get rid of space between the fender and tires also, with the good ride. And what brand should I go to? I am going for 20' wheels later.

 

Camber kits aren't included in coilover for the G platform. Some coilovers say they come w/ camber plates but that only includes some applications, camber can't be adjusted that way for our suspensions.

I've been recommending Tein Basis coilovers for those wanting a mild drop but wanting more flexibility when it comes to dialing in just the drop you want. You won't be running on OEM dampers which will shorten their life quite a bit depending on the drop and how it's driven. And if you keep to the milder drop for the coilovers your camber may be aceptable or you may only need a rear kit, but every G seems to be different in that regard so YMMV. The Tein Basis can be found for just a bit over $600 so about 2x what a spring drop will cost but IMO it's worth it.
For Springs, Eibach & Swift seem to be the most common and get overall good reviews.

 

I want to drop maybe 1 to 1 1/2....do I need camber for that if I use springs (swift or eibach)...i really want my wheels to be straight instead of butterfly hahahah or is it negative camber?

 

Like I said, every vehicle drops differently or at least different alignment shops/techs get the G to align differently. Some get by OK w/ nothing, although I'm fairly certain that most that make that claim will have quicker tread wear. And it's negative camber that will increase as you get lower.

If you get either of those springs I'd get the rear kit for sure, and you don't need the rear camber arms, if you can elongate the rear toe slot yourself you can also elongate the rear camber bolt slot. That kit will cost about $25 per kit and you need two of them for the back (4 bolts total).
