Foot brake drag racing

Still not clear to me what the goal is. Are you ever planning to race at the track? If no, then why?, street racing?

Lots of response regarding reaction time, but if you’re never racing, it will never matter.

If it’s about best potential et, i.e best 60’, the only place to make that better is at the track where you can trial different launch methods and collect data. It is car specific. No one can tell you what will work or do best for your car.
