Tamiya Brake Sponge Set (Mild, 1/2/3mm Blue)(15512)

A second brake sponge set alongside item 15492, using the same three thicknesses but a softer, milder sponge compound for a gentler braking effect, useful when a car needs some speed control without shedding as much speed as the standard white sponge.

• Sponge thicknesses: 1mm, 2mm, 3mm
• Color: blue
• Compound: mild (softer braking effect than item 15492)
• Compatible chassis: MA, MS, AR, Super-II, Super XX

Brake sponge works by adding friction rather than by acting on the motor: a strip is mounted so it drags lightly against a raised section of the circuit, scrubbing off a controlled amount of speed before a jump or corner, which matters because Mini 4WD cars have no motor braking of their own. Because this mild compound sheds less speed than the standard white sponge, it suits tracks where a car only needs light speed control, letting racers dial in braking strength in smaller steps across the two compounds and three thicknesses rather than jumping straight to a heavy stop.
