Fitting and delivery

The MTS S-klasse W126 replaces the original dampers and springs and fits on the original mounting points.

• The stated lowering applies relative to the standard suspension. If the car has a factory sport suspension, the lowering will be smaller.
• When fitting, check the clearance between tyre or wheel and the strut: at least 5 mm. If it is less, use approved wheel spacers.
• Tip for adjusting the rear: remove the height adjuster, set the spring seat to the new position and refit the adjuster.
• After lowering, have the wheel alignment checked, because camber and toe change as well.

Delivery: 4 to 7 working days while manufacturer stock lasts.
