Does the Firebird trip the mph clocks with the tire or the nose?

looks like the chin spoiler tripped the light BUT it also looks like the driver "tapped" the brakes causing the car nose to dip helping trip the light-- so much for the 3 inches-- FED 387

6 inches is the correct answer ----all others are all supposed to be at 6 inches--however some 60 foot lights may be set between 6 and 13 inches for cars that wheel stand long distances- I was thinking about static height of the vehicle of 3 inches--actually the starting line lights height I believe is closer to just over 2 inches--regardless looking at the picture the red car tripped the finish line light with something other than the wheel-- how he did it is for future discussion

Yep, finish line light tripped by the nose is very common.

Myron Piatek Yep, the CD for the pickup is better, but look at the last column. The CD X sq ft of frontal area is the real deal.

This was an issue with long nose ProStockers of the 80s.
Especially the Camaros!
