I gather that the default setting will be off with the ability to turn it on. I wonder if this will turn off the DSC and the Traction control or just one.

Thats what the button is for. Why spend 25 dollars on something that your fingers can do for free.

It is better to have the DSC on all the time and the ability to turn it off when you please then to have it off and have to turn it on. I mean, how many times does it really interfere with everyday driving? How many times have you read a thread on here about someone turning it off like an idiot and wrecking their car?

interferes on a daily basis.....on the track that is wink wink nudge nudge ;) If you are used to driving RWD performance cars, it is easy to judge the limits of the car. Since it is not a requirement to keep the TC on all the time, Mazda amongst other maufacturers prevent lawsuits by including this granny. Bypass is simply a relay.
