Epping Redlights and rollout change?

Roughly 1-5/8", but that can change depending on what stage beam height is required to come up with the right measurement on the track or sanctioning body's rollout wheel. Ironically, having the same physical rollout distance can result in wildly different reaction times, depending on the timing system. I'm not exactly certain why, but certain timing systems have certain characteristics... probably the type of photocells used, or their sensitivity settings.

A couple of years ago at the Topeka National event the tech official admitted after the fact that the roll out was changed for Saturday after the Friday night qualifying after the Pro Stock Bikes had issues with the roll out. It bit a lot of sportsman racers on Saturday when they hit the track for eliminations.
If changes are made every racer on the site should be informed not just those well connected.
My 2 Cents

The monster Kenworth Jet Truck could have something to do with it. It did blow half the foam blocks off the track. I never like racing after a jet anything.

Oh well, on to the next race!
