On a side note I get better gas milage w/out using it around town as I drive with traffic, but weekends when I can let loose and remian under 100 mph the gas milage drops by a few mpg...just my 2 cents.
When I bought the Z almost 9k miles ago I left the button on 100% of the time which led me to re read this post and see if anyone else had responded about the consecuences of any wear on the vehicle...is there any and where, thanks
