Been watching Lucas Oil raced amongst others out in Florida. I'm noticing alot of the cars are locking up the left front on entry as well as sparks coming from only the LR? Are teams only utilizing left side braking now? They use to turn off the RF and that could still be what's going on with the left front lock up but how about just the sparking LR? Are the turning off both Right side calipers now? Just some observations that I've noticed??
