Default ladder bar adjustments

how do you adjust ladder bars to get your 60' times down.... do you raise the bars or lower them.... whats each way do the car as far as reaction and handling?

Are your 60 fts varying about as much as you ETs?

Raising the ladder bar one hole will make it hit the tire harder. Whether that will make it faster or more consistant is an experiment to find out.

Default Ladder

The higher the bar, the more tendancy to wheel stand. The lower the bar, the more tendancy to spin.

I would go up 1 hole from where are now, a big percentage of vegas with ladder bar, tend to wheel stand easy, thats my oberservation, so take baby steps, as not to miss the sweet spot, you are changing ic as you make these adjustments.

I would adjust it to maintain, what ever angle you have now. it may only need a degree or two down if any, but check to make sure.
