All about your springs. The stock springs are a little too spongy to add lift and chop the bump stops without creating more body roll. The 913 coil springs would help your VX feel more stable with the bumps chopped.
I only get a little body roll on hard turns with 919 coil springs, no rear sway bar & chopped bump stops. I remember having handling issues when I had 1" spacers on my stock coil springs.
