Sometimes I see people have this metal bar above the engine. I heard it stables the car more or something.. What does it do... I think it is pluged to the point where wheel stuff is.
i think you are refering to a strut bar goes from strut tower to the other strut tower its just a brace to stiff'in the towers for cornering at higher speeds and looks cool
Strut brace? They reduce body flex and stabilise camber.
so it makes car more stable at higher speed?
