I am running the 1SS, so I only have the options of on/off for the nannies. I turn off traction control, but leave the stability control on. It does heat up the rears quite a bit, but the safety margin is more important to me overall.

Have you ever run full stability control with the 18" setup and did it feel fine or was it tripping more than it would normally?
