pro/sportman brake red light green light
Has anyone went from a sportsman brake to a pro or pro/sport
What kind of difference did you see in reaction times?
I’m running in no box bottom bulb class with a hipster pro brake in a glide running low 10’s
When I see the first yellow I put it against the brake/two step then drop my eyes to the bottom yellow so that I don’t anticipate
I cannot leave at first sight of bottom or I will be red
Thinking about trying a sportsman brake to see if it helps
Lights so far this year

If you have to sit on the bottom bulb to avoid going red, that's why your lights are erratic. That's a really tough thing to do consistently. A sportsman brake will help slow them down some but an additional hole is usually drilled in the rear of the case for a pro brake. I'm not sure if you'll have to plug it......other things you can try if you haven't already:
stage REALLY shallow
lower launch rpm
taller front tire
Does your car yank the front up out of the beams? If so, then maybe higher slick pressure or some suspension adjustments would help.......

Typically a normal pro brake isnt that way, I know the hipster isnt, I also know the hipster is a aggressive brake.
