I installed Alcoa's last summer. I love them. They are super nice stuff. A good price is even better.
The one thing I did find was that when you install the wheels make sure you center the studs in the holes drilled out in the new wheels. The holes are slightly larger than the stud and do not like to be off-center. I had a terrible vibration I chased for months until I found out what to do. The wheelsa re neither hub centric or lug centric. The factory steel wheels are lug centric and generally will not vibrate too bad.
Good luck.
