What happens when the front is spinning but the rear is still?

do I have TCS? It's an '04 WRX

Nope. Traction control wasn't added to WRXs until 2008.

Oh, thanks again. I don't understand TCS on an AWD :/ Oh well, the less assists the better if you ask me

The less the less is there to break. I certainly could do without most of that stuff. I used to have an old GrandCherokee, limited. Most of all that "luxury" stuff was inop... Once it's to that point there is no chance of getting it fixed up, way too expensive. One item at a time, maybe. But for ALL of this junk, that's just nuts. ABS, climate controls, self-adjusting mirrors, seats, light bulb monitors and so on... Plus some of this junk is government required, like now 3rd brake lights, Traction control and TPMS. That only makes cars more expensive than they need to be, and more stuff to brake.
OK, now I'm just getting riled up, better quit right here...
