Which do you guy think would look better with my stock formula rims? Does the Pro kit really only drop it an inch, or does it settle and get a little lower?

I am thinking the pro kit will look best with the stock wheels because it isn't too low. But will it settle to lower it more than an inch?

No, and you may not actually see a 1" drop if you are still running the factory springs on your car now. Factory springs sag and often times ive heard of people adding pro-kit and keeping the same ride height.
I have pro-kit on my car, satisfied with the front but my rear didnt lower enough.

I have the WS6 suspension and it is very firm, I dont think it is sagging at all.

How did you like it slammed with the stock wheels. Which kit would you get will the stock wheels since you already had one kit. So would you stick with the sport lines with stock wheels or get the pro kit?
