Viermalvier.de, das Geländewagenportal Forums Marken talk Land Rover Fahrwerk - OME / Caster Kit - Abstimmung

Besonders pfiffig ist, daß in der Summe das Desert-Rover-Auto und RockWare-Auto die meisten Punkte bekamen bzw. am ausgewogensten!! waren. Diese Autos war (wie alle anderen) ein 90", aber mit RangeRover Federn vorn und OME hinten bzw. rundum OME-Federn. Und besonders beim Desert-RoverAuto erinnere ich, daß die Nähe zu Serienteilen am größten war.
Alle anderen Extreme punkteten mal irgendwo besonders viel, aber Nachteile in anderen Disziplinen machten das wieder wett.

Vehicles with balanced articulation front and back can also afford more total articulation than those that generate most of their articulation from one axle.

Articulation improves off-road performance if there is not so much of it as to negatively effect the stability of the vehicle

Another effect of the suspension lift is it changes the kinematics of the suspension. Raising the front can increase the bump steer because the drag link is no longer parallel to the ground, and decreases dynamic stability because caster is deceased. Most people understand the effect of these changes. A more esoteric change is the possible change in height of the roll centers for each axle. A roll center of an axle is the point that the body appears to be rolling about, in the same vertical plane as the axle. Standard practice is to design the suspension such that the rear axle roll center is higher than it is in the front because this improves straight-line stability of the vehicle. When a D90 is lifted, the rear axle roll center stays the same height (i.e., at the center ball joint), but the front roll center is raised because the center of the Panhard rod also raises. The result is a decrease in directional stability, resulting a bit more darting about on the road in response to road irregularities.

One is the increased tendency to produce body roll because of the longer vertical lever arm between the cg and the roll centers. One can control dynamic body roll through stiffer shock valving, and dynamic and static body roll through stiffer springs. Unfortunately, stiffer springs and shocks reduce ride comfort, and stiffer springs reduce articulation. Other more serious disadvantages of large lifts are the decreased angles at which the vehicle is stable and the increased weight transfer to the down slope wheels. Vehicles tend to climb better if they can keep as much weight as possible on the front tires. Finally, lifting a vehicle increases the angles in the trailing arms, which leads to the jacking effect discussed earlier.
