Your choice of rims are nice. However, I personally think going 19's on either a P10 or P11 is too much.
I have a hard time believing the rims ride just like 17's, especially since you have essentially no rubber there. Have you hit a pothole yet? With my current setup, I brace myself when I see a bump or pothole on the road, I can't imagine how I would react riding on 19's (not that I ever would). You hit a pothole and I'm sure your rims would be damaged.
With 19's, you're taking away the focus of the car as a whole. You are putting too much emphasis on the rims. 17's with a nice drop is perfect in my opinion. The P10's body is higher off the ground than the P11's and so the rims make the car look like it's on it's tippy toes, or rather the rims are holding up the car. Even the P11 owner that had 19's - even his car was dropped, but it was still high off the ground and it just didn't look right.
Remember, I'm not here to bash - I am here to state what I honestly think. I'm not going to say, "wow, those are sick" etc, when I think that 19's are over doing it. You can get enough respect riding on 17's with a drop.
As long as you're happy :rambo:
