Griding noise in the front end.

[SHO n GO]

Hey guys ive noticed when on snow and i get the rear end to step out on the SHO i get this nasty grinding noise from the front end. It happens with the TCS on or off. Any ideas of what it could be? The first time i thought it was a tire catching dry pavement but after it happened two other times on solid ice it has let me to wonder what it is.

Stability control applying brake pressure upon detection of wheelspin?  A rapid on/off could cause that grinding/crunching sound.

That could be it. Also i noticed if i dont try to correct the slide it dosent do it only when i turn the wheels to correct it will crunch/grind.
