Stability Control install?

[MyPrixGT06]

I was wondering, my car didn't come with stability control, but found a stability control unit for my year car for $60 and wanted to know if its a plug and play or does it need a lot of mechanical upgrades to accomplish stability control? I figured since my car has abs and traction control it would be almost plug and play, because they do the some thing, give brakes to the tires that needs it and less to those who don't.

you need ALOT more than that one sensor...

short answer, its easire to sell the car and buy a different GP that already has the Satbility control
