If you are indeed going for a max. performance, setup, then I would do SportLine versions springs, struts, swaybar & bushings, AND control arm bushings.

The rear shocks & accummlator cannot handle SportLine rear springs, so have 500E rear springs and 500E rear swaybar with 500E swaybar bushings.

I had H&R's with Bilstein Sports in the front, and they didn't handle nearly as well the full SportLine setup up front and 500E rear spring & swaybar in the rear.

You'll like it.
