It depends on how good you are at "feeling" 70 ft-lbs torque. They all need to be tight enough, but not too tight, and all kind of the same so as not to warp the rotors. I'd go ahead and get a torque wrench - the beam-type ones are fine and not very expensive. 20 bucks in the latest Sears catalog. Good enough for lug nuts. Really a good thing to do on ALL your cars.
