I chose my 18x8.5 BBS RK II's based on the following reasons:
1. Looks - They looked much better than stock AVUS
2. Wieght - More than 5 lbs lighter than stock per wheel
3. Strength - Ability to handle Colorado's worst road conditions
4. Repairable - Ability to replace outer rim if badly damaged
I have hit some nasty potholes and badly damaged road surfaces in the last two years and have not had any damage or warping of these wheels or any problems with balancing them. I also have been using Goodyear GS-D3 tires which have a large lip protector which has helped keep scaring off the lips of these wheels. GS-D3's way-out perform the stock Michellin Pilot Sports in many ways. I would suggested them to anyone who can afford them every 20-25k miles (maybe less if you track a few times a year).
If your car is driven 50% or more of the time I would suggest a little function over performance in the wheel area; unless you like dropping money on wheels every couple sets of tires or every few pot holes
