I've gone from knock-offs (Diablo) to JDM wheels (Weds) all sorts of Lexus OEM wheels and now BBS.
By FAR the BBS wheels are the strongest and I don't see myself buying another brand. Having driven the same roads, tracks etc with the same car (GS 400/430) with different wheels, I KNOW the BBS wheels are worth it and are built to a higher standard.
I do agree wheel failure can happen to ANYONE/ANY WHEEL under certain situations but there is a lesser chance with PROVEN wheels.
I find wheel/Tire choices to be among the worst among people. The other thing I don't get is putting great wheels on your car with crap or average tires. WTF?
