I've got an air one too, but the electric is awesome trackside for tire swaps.

The electric ones are obviously going to be larger than the pneumatic ones. However, what bolts require >150 ft/lbs of torque on the Z? Prior to purchasing my Makita (rated at 260 ft/lbs) I didn't find anything above that number in the manual. I did just check bolt specs for the CBE, suspension, wheels, and anything related to front-end work (front strut tower, end links, mass dampener, etc.).

You do know you need more torque to take something off vs putting it back on right?

taking off the strut would probably require quiet a bit of force

Ideally though you'd use an impact wrench for removal and a torque wrench for tightening. With a torque wrench you can set it to the desired ft/lbs and just rotate until it clicks.

That said, most people just zap it with the impact wrench and call it a day.

Agreed. I usually use the impact if there's a stubborn nut/bolt, but for the tightening, just a normal wrench and then tighten to spec with the appropriate torque wrench.

Fair enough. My comment was aimed at questioning the upper bound of how much torque you need for an impact wrench. If a bolt is rated at 150 ft/lbs, then having 2x that amount on the tool seams reasonable.

If an electric impact wrench won't cut it, that's why they make $20 breaker bars.
