it says in the Eibach springs installation manual that after the installation of the rear springs, the fasteners (/sth bushing related) need to be re-torqued with the full weight of the vehicle to avoid pre-load.
They recommend a drive on ramp to do this.

Would I be able to use a jack to jack up the suspension link and torque it that way?
Would I also need to do this for the front springs, front sway bar, and rear sway bar to avoid pre-load?
