when you put a saph anti roll bar on a 3dr it pulls the wheels closer to the front.better handling supposably.
when i first got my 3dr it came with 1 on.
i changed the wheels what it came with and the tyre caught the front bumper so put the standard anti roll bar back on.
the handling seemed no different what so ever to me.
plus as it pulls the wheels forward the wheels dont sit in the center of the arch which does'nt look right.
