Philippe, we call these speed bumps here in the US. However, this sounds like
a much longer speed bump than we have here.
If the problem is in the rear overhang, raising the front may make the problem
even worse. If the problem is in the front, you may want to consider
installing stiffer gas shocks in the front.
Raising a car 1" higher above stock may not be a big deal. It might mess up a
bit with your alignment setting, but that's it. Trying it will not hurt
anything. It could however make your car a bit more unstable in cross winds,
and if you like to drive fast, it will raise a bit your wind drag.
