Bump stop selection
After lowering & changing suspension, spring rates etc., we are often faced with a multitude of different modifications that require different bump stops, either in rate or height.
After installing a new rear end, the factory stop no longer functions. I would like to add one on a different frame mount or to the shock location.
There are different foam & rubber combinations, plus high rate "bump springs" that can be used in the top of many shocks for travel limiting.
Obviously, running over a road imperfection mid corner & landing on a solid bump stop can end badly.
I'm assuming the stops should never come into play under normal conditions.... even though many aftermarket lowering kits make the bump stops part of the normal working suspension.
Does anyone have a starting recommendation as to the spring rate & amount of compression you shoot for with respect to the final suspension limit?
Should you start with a percentage of the vehicles spring rate & have it come into play at say 1" from maximum travel?
For example with a 250lb rear spring, do you choose a stop with a 500# rate starting at 1" from mechanical interference?
