Is that an assault trigger?
I think Keith Richards and Mopar_Rich both tried them at one time or another. Don't know how long that lasted?
Maybe one of them will add their .02... What's the motivation here? More consistent reaction times? The trick here is to get as consistent as YOU can be with whatever you are using for a "trigger" and adjust the car from there. As dumb as this sounds, if you are wearing safety gear in the car you should practice while you are wearing the gear. The Biondo delay boxes are great for their big screens and built in practice functions!
