Yes you need fender flairs and your alignment spec sheet print-out.
I just moved here, I have (on my 3rd gen) 3" toytec springs(emu) and 2" spacers and 16x9 offset rim w/ 285x75 BFG's
you need an appoint with the reconstruction inspection station,

I didnt need fender flairs, because my 4runner Limited stock flairs covered my tires. (i was told that the part of the tire that touches the road must be covered.)
But I needed mud flaps to cover the back, rear tires. Half way down the back of the tire.
I just got Lex Brodies to do the alignment, they can handle larger trucks.
They charge $125 for an alignment.
You also have to claim any engine, exaust, intake, or drive train mods.
The only inspection station is under the H1 over pass at 1112 Kapahulu Ave.
hope that helps.
