Luciano. That kit is just a copy of the old Tamiya kit. You will find that the fit is poor, particularly around the rear hull panel and exhaust. The Suspension is basic, the dampers are completely innaccurate, the under part of the hull is incorrect, the return rollers are not correct for either the rubber lined or steel version, and the overall detail is poor.
There are much better Panzer IV kits out there, if you are prepared to pay a little more. Tamiya's latter offering as well as the retooled DML J(?) being the obvious choices.
