I've run the same pair of Monocoque "Aluma-Lites" for about ten years now. Weighs about 7.5#'s. I've never had a problem. My car is approximately 52% front weight and it almost always has the front wheels off the ground with it's share of bouncing around also.
Now I do refrain from the road race antics on the return roads like I see a lot of racers do because a wheel like this is not designed for ANY side loads such as fast cornering.
