Box and No Box

has as much to do with the convertor as it does the quality of your brakes.
2k, 2.5k, 3k it’s unlikely your gonna see much if any difference in 60 foot/ ET from any chance of those spots, it’s still gonna hit at where the convertor latches. Bigger effect is reaction time
Definitely something I'll have to figure out in my driveway, I'm thinking my convertor will be around 4800
