The standard Bilstein 4 seater shock absorber has a large bumpstop.
I had problems with this as the springs settle on it causing handling problems.
I changed to AVO's from Tim Ayers and the ride and handling is much improved. I set them at 3 stops for general use. They have been recalibrated so the normal setting is in the middle of the range.
I have however added my own adjustable Mini bump stops which are attached to the roll bar. This allows you to pass over road humps without feeling the rear axle is joining the rear passengers.
