Good topic.

I've measured my home track at 5". The body work on most tube cars will trip the beam with the nose. I saw a finish line photo of two comp cars (I believe Arnie martel was one of them) with one nose clearly in front but at full throttle it was high enough that didn't trip till the tire. The opponent's car was lower, a good foot behind, but because he tripped with the nose, got the win light. It's a quirk of the system.

Full suspension cars such as stock and superstock will trip with the wheel unless the driver drops hard, which collapses the suspension and trips the beam (often) with the front spoiler...this gets complicated because now the driver has tried to kill some et and actually picks some up. Makes for some funny numbers.

I believe it's actually pretty rare that it happens.
