Misc Vintage Racing Clips

My guess - lowered the chassis and kept full range of suspension movement?
Looks like a "mini" spoiler? NO Wing? Maybe saw a Diffuser in the last frame or 2.
Belly pan? Full qualified cage?
Not quite a GS - Could be much- much fun.

Cheers - Jim

Texas Big Bend Open Road Race:
  • Corvette ZR1 reached 213 mph during its record-setting run.
  • Heat from straight pipes caused the rear bumper to melt.
  • The tuned Corvette produces 30 % more power than stock.

This heavily modified C7/ZR1 claimed a new record. But will need some body work for all the success.
Stories cite a modified exhaust system as the likely cause. But it did the 118 mile run at an average speed of 173.004 mph!
That was a 41 minute run! SWEET. CANNONBALL!

It may not "Buff Out!"

That is an aero problem. That great big, and highly efficient nine lives wing created a ton of low pressure above the deck which drew very hot exhaust gases up the back of the car. The modified exhaust and tune contributed some by creating a hotter than normal exhaust plume, but the aero is the primary contributor.

The exhausts exit inside of a channel (that is part of the diffuser?). Would they have been better off exiting the exhaust away from the body work, Like extending the exits?
 
Auto x. Searched and this one hasn’t been posted. But, the original videos of each car might have been posted.
