DESCRIPTION Mass dampers are a common upgrade for Mini 4WD cars. They add stability by helping to absorb impacts after a jump. This set expands the line-up of mass dampers with smaller (14mm long) block weights than were previously available, giving you more setup options to take on tricky circuits. At 3.6 grams each, they are 4.7g lighter than 6x6x32mm blocks. Includes: • 6x6x14mm Brass Mass Damper Block x2 • 2x20mm screws and small parts for attachment included. • Compatible with MA, FM-A and AR chassis cars. • Note: Some bodies may require modification.
