Need help, Air or Coilover for LS430

Here's the problem
I have some 8.5x19 +37 F and 9.5x19 +37 wheels with 225/35 F and 235/35 R tires
25mm spacers all around

So the front and back wheel stick out about 1 inch.
I'm planning to slam it but not sure what to do.
If I have coilovers then I have to buy camber which cost about $3000 just for the cambers Nagisa. :sad:

Just want to confirm if LS430 has OEM front camber and can go about -2 degree?

Is it true that if you have airbag, you don't need camber arms? And if I get Airbag is about $5000. I don't know if I get that Airbag, then when I low my car, will the wheel automatically tuck in?

Please help

how about getting some smaller spacers

I imagine he using that big of a spacer to clear the caliper.  Otherwise, get a smaller spacer.

Smaller spacers will do the trick,unless you're using it to clear your claipers, there is 
no need to buy camber arms. 

Also its not true that having airbags alone will solve your problems.
