all depends what sort of suspension you have, if they are adjustable platform coilovers then you can wind them up but still have the risk of them not going through becauase coilovers are illegal, however when my 33 came over from japland my coilovers went through ok.
most of them time, if your guages are below the dash line then theyll be ok, keep tread on your rears, not too low, not too loud, dont be stupid on the road and they'll be ok about it
