Hey rooman,
Bracket racing my friend is a different world to win in. Not saying to race in, but to win in.
5 tenths, full tree with no electronics car is not the same as a car with electronics. Have you every built or run a fed to leave on the flash of the third bulb? Where you have to try and keep the front tires in the beams a extra .100, a whole tenth of a second. Jon Hansen (Hayden Wheels) may know the differences here.
A 4 tenths pro tree or electronics car just needs to get out of the beams as fast as possible. So what I meant was consistency of front tires in the stage beams because were in there a long time. If I ever run a 4 tenths tree I would run the smallest possible front tires we could. Less is more, less time in the stage beams the more consistent it will be. Like I said earlier we run 25" fronts bottom bulbing with 18" wheels from Jon
Not saying it cant be done. We won comp eliminator at 74 sportsman nationals running as a b/ed. First year of the econorail. We did it in Kuhl & Olsens last front engine car. Mike has it back now and restored as a top fueler. Only national event that car has won. Learned from that Woody Gilmore car about chassis sag.
Ackerman geometry is set at 1" stagger. But I do add or take out a inch now and then.
Yes sir, the center of our lane is our only concern. Except the last 66' of the race track.
In bracket racing knowing how much time, you and your competitor spent in the last 66'. That's bracket racing
Have fun. Enjoy
