I’ve got EV Base, which are basically Hansshow. I’m perfectly happy with these, since they’re used as steps and not sliders. These are not retractable, however. I self-installed and modified my panels to fit around the brackets. EV-base sells their own panels that fit around the brackets as well. As far as removal of TP55, def breaker bar over impact for sure. You are far more likely to strip and damage your bolt with impact than with the breaker bar.
I have Weistec rock sliders. I like them. Easy install, super sturdy. They completely cover the area exposed by the plastic panel removal. They keep mud and dirt from the tires off the paint, and help protect from parking lot door rash.
This is a bad idea. Most torque wrenches (other than beam deflection type) are calibrated in only one direction. Using them under load in the opposite direction can result in damage and calibration loss.
You have to check the documentation that comes with the wrench.
You are correct, you'll have to remove some panels. It is not sealed and is already exposed so you'll be ok. I left mine off as it was easier than trying to manipulate them to put back on. Some manufacturers have replacement panels. Rock sliders should not reduce your ground clearance, depending on the ones you select, as opposed to most running boards - so that is something to keep in mind.
