Depends exactly what you're trying to specialize for. The typical thing to do is treat it like a flanking medium, and use vents, stabilizer, and rammer. The alternative is the active scouting role, for which you could use vents, optics, and upgraded suspension. A number of hybrid builds are also possible, depending on exactly what you're willing to sacrifice. The only trouble is that doing so muddles up your ideal tactics. But just about any choice can be justified so long as you treat the vehicle accordingly.
