its not dangerous for the rigors of daily driving. track with 350+ hp/tq then maybe.
but im running pbm coils and i had the same issue with 16x8.5 ... its bc you need a lower offset on your rim.. or a 25mm bolt on spacer. they are safe as long as they are not "slip ons" and torque them to about 80-85 ft-lbs. then about 75-80 for the rim studs or what ever you normally do.. thats how ive been running but im slammed on the powered by max coils and with a 38mm hub-centric ichiba spacer... and shitty budget enkei rims... good rims bad rims/safe dangerous.. blah blah. its not like widening the track of your tires with a mostly stock suspension arm set up as well as lack of race stiffness despite having coils,, will make a noticeable if at all dangerous set up. in other words the more suspension mods you have and the lower and stiffer you are the more dramatic the effects of your geometrical changes will be noticed. and easily dialed in. but always beware of pot holes and debris as the impact may lead to failure of any sort not limited to spacer strength.
