Not trying to point out right or wrong but trail braking is huge is every type of auto racing. At the bondurant school, they have your Shifter hooked up to measure trail braking which of course has front brakes. I do not know a single driver in shifters that do not trail brake. Maybe it’s old school but everyone I have raced with does.
Just my experience,
Ps. I will test this while in Phoenix this week. I will have Alan help me with the data and let everyone know the results when I get back.
