pullbar spring

[Deish98]

We always run good at 3/8 mile tracks that are dry slick we struggle at 1/4 banked heavy tracks if I soften the pull bar spring could that help get more bite quicker since the straight aways are shorter

I believe it would be just the opposite , someone correct me if I'm wrong.

softer spring slower reaction,,stiffer spring quicker reaction..windy..

depends on how far the pull bar is mounted off centerline of the rear end.
typically you would stiffen to help with traction, or raise the mounting point up in car. both on chassis and rear end.

agree deff stiffen

stiffen to the point of bust the tires loose then back off a little
