I have global west uppers, stock lowers, granada spindles and stock power steering. I also have 1" lowering springs.
Yes, they bolt on to the originals, then you bolt the wheels up. Mine are aluminum so I am not sure about the stresses of autocrossing. You might want steel ones for that... not sure.
