i love the s2 front more than S1
anyway i just did a conversion and was rocking it with S2 bonnet grill and headlights with the S1 front bar for a while till i got the S2 bar and yes it fits fine you will need the S1 reo bar though and only other thing is that the headlights are sharper on the S2 so the S1 bar comes out past them by about 1cm and there is a gap looks ok from a distance but up cose looks like the front dosent line up.
hope that helps
