Trying to rake my car.

you could try backing the torsion bar adjusters out a little bit. the adjuster bolts are located on the lower control arms and are accessed from below. they're the big bolts you see sticking out the bottom. but beware, it will affect your alignment and suspension efficiency depending on how much you back them out. better way would be put some XHD rear springs on or have your existing springs re-arched.
