If you have bolts and not studs I wouldn't risk the impact wrench on them. Such a short amount of threads to get through and they are designed to expand. The impact wrench seems like overkill.

With studs there is such a long way to go - and they are tougher then normal wheel bolts - a good impact wrench is great. I always break the nuts loose first though and I only spin the bolts on with the IW. I do final torque with a torque wrench.

I only bought a 14V Bosch so it couldn't loosen and torque the bolts anyway.

Just my reasoning and way of doing it.
