If you check out my post in the Track Day / Motorsports category, there are some track videos. My hood bounces all over the place at speed.
Some model years had an extra rubber gasket on the hood, but I think that was only towards the nose. The easiest way to fix it would be to get ahold of some of that rubber gasket/door seal material and attach at the windshield cowl area under the hood to help support it.
I would caution that anyone doing so to NOT have the gasket span the full width of the hood so as not to impede any potential hot air flow/heat radiation from there. It is a high-pressure area, so it’s not too likely that air flows from the engine bay out to the windshield, but better safe than sorry.
