I didn't say it actually twists the chassis, but do this enough times, and you'll start to experience new squeaks and rattles. This is true even with race cars, with all their cages and added bracing. That's part of the reason teams retire them after just a season or two, then sell them on the cheap. You won't find Turner or BimmerWorld running the same chassis for three seasons, even if they've never been wrecked.

I suspect jacking the race car is only one small part of why the chassis of a race car fatigues. Although, to be fair, I have heard Bill Auberlen complain on the Continental Series broadcasts that the car is squeaking!
Saying that, I hate corner jacking, even if it is doing minimal damage.
