Say that the anti-roll bars

Say a personal opinion: I think the top of it even though it can strengthen the body stiffness, but it must be, and other measures to strengthen the body at the same time applications, such as: installation of vehicle chassis;h beam connecting rods top bar after installation, etc., in order to achieve good results.
If you install a separate "top bar", it just increases the rigidity of this part of the body between the car around damping tower. At this time, the power generated will be distributed to the wheels other "soft" parts of the body, resulting in deformation of the other parts. In fact, this time positioning data suspension system will still appear biased. At the same time, should have been deformed by the whole body to withstand the force of the part of the body to bear, this part will certainly accelerate the aging structure.
Say that the anti-roll bars.
Anti-roll bar is connected to two wheels and underbody coaxial and elastic metal rod, which is part of the suspension system. Through its flexibility, limiting the movement of the two wheels,h beam conrods said the body is inclined to suppress. Plainly, that is produced when the body tilt, balance bar high side of the body will down "pull", the shortest side of the body up to "push."
I put my Jetta front anti-roll bar of the original 18MM 22MM thick replaced by a thick shaft VW factory in Germany, and the rear axle fitted with a 25MM thick NEUSPEED rear antiroll bars. EIBACH dwarf with spring and damping SACHS PERFORMANCE movement. Now the car when cornering roll is relatively small, the steering reflect quite flexible, flexible to be able to use the "thief" to describe it.
