Pretty sure spacers are illegal in all states.
When looking for spacers, try to get hub centric spacers. Puts less strain on your wheel studs, but I guess that really depends on how wide the spacers are going to be.
It's illegal, but what modification to your car isn't these days...

Page 2, there's something about HID lights. Pretty sure there was something else, but that's what I found first so...
Ah that's not too bad. From people's response in another thread, those specs would stick out quite a lot (at the front), but it's perfect in my opinion.
Kings springs are usually soft as well aren't they? Something like 2.5kg/mm? Being that low I would it imagine it bottoming out over every ditch/pot hole.
Here are some photos to compare from standard lights to 6000k HID kit lights.
Look at those hot spots, glare and shocking cut offline.
Edit:
Here are some pictures to show you how good some retrofitting lights can be.
He's running,
"Acura TL Bi-xenon projectors
BMW E46 (ZKW) clear lens swap
4300k OEM Philips D2S capsules
OEM Hella Gen 3/Philips LVQ-212 ballasts"
Putting HID's into a car that came out of the factory without HID's is illegal. Doesn't matter what temperature the globes are. They're illegal. Even those who have retrofits. Without cleaners and some balancing thing I don't know and engineering, it's illegal.
Don't go for anything above 6000k in my opinion. 6000k is blue/rice enough for me. If I bought another kit, it would definitely be 4300k.

There's a post made by someone with 18x10 +10 all round. I don't think the 18x10.5 -23 will fit without some major work done.
My advice is that if your wheels fit in the guards without stretched tyres, don't get stretch tyres. Get tyres that are best for the wheel's widths.
Stretching tyres when it's not needed is becoming the new 'rice' mod in my opinion.
How much more do you want the wheels sticking out from what it is now? What widths do you want the new wheels to be? What are the current wheel's specs?
Give me those details and what you want then I'll tell you what offsets you'll need for that fitment.
Cheers
