Lowering For Handling

For road racing, autocrossing, or just taking that curve in style. Oh yea, and stopping!

Hi Red hot,

With a driver and full fuel tank, your front trailing arms should sit nearly level. "Nearly" usually means a slight downward slant toward the rear if no luggage or load is present in the trunk.

Lowering the front ride height too much has the same bad side effects on a VW as any other car, loss of ground clearance and loss of suspension travel ... but on a VW it also affects roll, effectively stiffening it, and caster, reducing it.

Too little caster and you wander as you try and drive straight, and you lose your self-centering correction as you transition from a turn into a straight.

Lowering the front end on a swing axle car without an equal drop in the rear promotes dangerous braking and cornering instability. The effect is less on an IRS, but still exists.

Well said FJC, the part about the caster angle change is so important and is all too often forgotten about especially when dealing with the lowering and raising of a vehicle.
