For a "big bar setup" the effective spring rate of the bar needs to be greater than the effective spring rate of your coils. This pulls the inside tire up and will compress the suspension due to cornering loads. Unless you have a silly light spring rate 1.125" bar ain't gonna do it. You will need a 1.375"+ diameter before you get into big bar territory.
