i just ordered h&r 12mm wheel spacers. the h&r spacers are hub centric and are made for this specific application. (12mm = about 1/2") new lug bolts are also included.

since i lowered my crossfire...i feel the rims/tires sit too far in the wheel well. i like the wheels to be close to flush with the wheel well edge.

i will take some side profile pictures before and after install.
