Please do not cut up your front crossmember!

As mentioned above, you need to detach the rear ends of the lower control arms from the frame. You also need to:
-- Remove the "skid bars" between the crossmember and radiator
-- Disconnect the steering column from the rack
-- Detach the shocks from the lower control arms, or just remove the shocks
-- Detach the brake calipers from the spindles, or detach the hoses from the calipers
-- Detach the coolant tubes from the crossmember (10mm bolts, hard to reach)
-- Disconnect the sway bar end links
Hopefully, I didn't forget anything.
