    Bump stops lenght

    Hello there,
    I understand the concept of the bumpstop, been reading through Nighttiger's excellent guide. What I don't understand is how you determine the right lenght of the bumpstop. From what I get even a 5mm bumpstop will prevent the chassis from bottoming out, but then whats the point of having it at 2-3mm or 10, 15, 20mm?

    To run the lowest ride height and fine tuning your clearance to minimise scraping.
    For bigger bumpstops, its to limit suspension travel, as some cars have greater travel than they have ground clearance leading to situations where they can bottom out. So the bumpstops can be used to limit travel and run a low ride height.
    And lastly with large bumpstops I believe you can use that almost as a secondary spring with a greater stiffness to limit roll or crashing over kerbs, where high spring stiffness isn't available as an option.

    Thank you for the explanation. So do bump stops don't change the ride characteristics while not engaged but they only work while the suspension hits them, right?
