Upfixin, I actually understand your explaination. Thanks for posting. I wonder if an indication of this damage might be suspect if the front rub guides on suspension are beat up bad. Carl/928motorsports carries the chin protectors)

Thanks JoeJoe. I'm going to repost this, but in reply to your question: yes and no.

They could be knocked about by scraping over speed bumps or kerbing at low speeds, or by higher speed impacts eg grounging the nose @ 60 going through a sudden dip in the road.

If the impact(s) have been severe enough the gap between the top of the front guard and the panel at the base of the windscreen will be narrowed. This means there is a slight but permanent upward bend in the chassis rails at the base of the firewall.

I think the great majority of cars that have been 'driven' on a variety of roads will show some signs of this. They'll also have hatch latch problems.

Carl's chin protectors will only prevent the 'chin' of the each chassis rail from being scraped, as well as keeping the spoiler from scraping.

They won't protect from impact damage as they're bolted solidly to the chassis.

I've thought about a variation on these eg as a shock absorber: bolt the protector against a friction plate with a pre-determined tension, so that the protector can move once a damaging impact occurs. Correctly designed, this could cut the impact g's by 50%.

After a walloping impact (and you'll know when you've had one ) the friction plates will have to be unbolted, realigned, and bolts re-torqued.

Just an idea I've been mulling over.
