What kind of spring rate would you couple with this for the rear leaf spring package/shock as well as sway bar rate for a car that is driven to a local road course event .... a true road and track car. This would be in a RB powered E body that has not been lightened up much so around 3800# wet without driver.




In this situation, it depends on what, if any, rear anti-sway bar is used. With no rear bar, 175#, with a body hung .75" bar 155#, with a 1" axle hug bar, 135#. This should at least get you in the ball park where you can then use tire size, pressure, or rear bar adjustments to dial things in closer.
