Does the JCW sport suspension work like the upgrade OEM sport package where a button is needed to be pushed to activate these features? Or is the JCW sport suspension always active?

I am one of those who likes to use the button, because I don't always like the bumpy ride (for those of you in Chicago, you know what I mean!)

 

If you are talking about the Sport button, it does nothing to the suspension. It affects throttle and steering response. My understanding is that steering is just a change in the power steering assist level.

 

He's talking about the JCW suspension kit, not the sport button.

To answer your question, no, the JCW suspension does not offer a button to make it more or less firm. It's a "hardware" swap. New springs, shocks, sway bars, etc., and from what I hear, it is firmer and more harsh than the factory sport suspension.
