Well in that case, if it's Subspace then you have to use Warp Nacelles like that on Voyager (Intrepid Class). Someway unknown to me the folding Nacelles don't cause damage to subspace (Subspace allows warp travel but is damaged by Dilitium waste, right Ian?). Anywho, yeah without the enhanced warp drive found on Voyager any warp factor is hazardous to Subspace, it all depends on how fast you want to go and how badly you want the future to be warpless.
EDIT: In fact I think that warp nodes or gates or points (So on and so on) are way better than free roaming warp capable vessels. Of course it's not like the damage caused by Warp travel is enormously signifigent, most damaged Subspace blends in with unharmed subspace (like sugar in water), but if everyship in the galaxy were to go to warp at the same instant subspace as we know it would cease to exist and warp drive would only be a dream once more!!
So remember that when to super charge your asses home kiddies.
