those will Stillen sways...what's your setting?
 

For the rear? There's only 2 holes, soft or hard. What is your experience with each? what do you recommend with stock non sport suspension and OEM 19s?

Thanks.

There are only 2 holes but that gives you 3 settings:

Both sides in the soft holes
One side in the soft hole the other side in the stiff hole
Both sides in the stiff hole

My rear is set to the softest setting and the front is set to one hole above the softest setting. With my Tein SSPs this yields a nice neutral setup. I can get the tail out with the gas pedal if desired but it is easy to reel it back in. It took me a few test drives to dial in my Damping and sways to get a setup that I liked. I would recommend that you experiment until you get it dialed in to our taste. Stiffer in front increases understeer (decreases ovrsteer). Stiffer in the back increases oversteer (decreases understeer).

Here is a suspension setup quick reference:

There's only 1 hole in the front.
