I had 2" spacers on my FJ cruiser with no problems at all. i went light off roading, but mostly took it on the beach alot. Never had any issues with the spacers ever. I also have some 2" spacers on my '66 dodge A100 van, again all good.
I sold my Fj about 2 months ago and now am the proud owner of a '99 VX... first thing i did was put some wheels and tires on it. the reason y i am telling u this also, is because i found a sight online which is very reasonable with their prices...
i bought the 16" Rebel Racing Outlaw II, black wheels which have 2" of neg spacing(cmpared to oem vx wheels), wrapped in 275 65 16 bf goodrich mud terrain km2 tires. they poke out, look freakin so dope n only cost $1066 delivered to my door.
So either way u go, feel confident n know that u won't have to spend too much money, if u do decide to go with new wheels....

oh, i will be posting pics tomorrow with the new wheels and tires. i was waiting til i refinished the cladding with gatorback spray, which i did today, and the results were un ******-believable... and permanent!
so look for my pics tomorrow for sweet wheels n BLACK cladding examples!
