I actually agree with ya Mike . . . I've owned a number of cars now and haven't found the TC3 to be, really, any more or less fragile than any of the others - and they don't call me Boomer for nothin, as our race director just LOVES to say. . .
I would say, though, that the hinge pin holders, both front and rear, are fairly weak and the holes tend to become elongated giving this wonderful "variable toe" effect. . .would love to have alum or adjustable ones. . .
Also the hinge pins need to be stronger. . .
The only other thing that I just don't like, so much, is the steering rack. I would love to find someone who has replaced it with a bellcrank system. . . <hint hint>
