Could be, but it is a possibility the torque shock from a hard shift can do it. I've just seen way too many to think people are that ignorant. I mean, I've had 7 of these little cars, and of the current flock 3 are bent, counting the Poupe'. 2 of the others I have had and are gone were bent too. I mean, if there are that many people out there that would not know enough about their cars to bend that many of the same pieces!! Sends shivers down my spine! Besides, it's been the right side only that I've seen so far. So just for the sake of my own sanity, I'll go with weak components. I'd rather reinforce a part for a competition, and be safe! Although the only real thing that goes out of whack is the caster, not sure if that would affect the rear suspension as much as the front. Better safe than sorry y'know.
