Yea that's what really matters - but anyhow - VDC off isnt the worst thing ever - unless its wet out VDC stays off in my car - but anytime I get suspension / power mods done - it comes back on until I can drive 95% of the time w/out the lights kicking... once I am aware of the limits of the car and get a good feel for when its going to kick in - I start turning it off - but its a constant exercise in learning to drive the car
