Moton 1-Way Series Coilovers – BMW M2 / M3 / M4 (G87 / G8X)

OVERVIEW

The Moton 1-Way Series is the entry point into Moton's motorsport-derived coilover range for the G87 M2 and G80 / G81 / G82 / G83 M3 / M4. It is a single-adjustable (rebound) non-inverted monotube damper with ride-height adjustment, built by Moton (AST Suspension) in the Netherlands with application-specific valving and springs. It delivers serious street and track-day performance without remote reservoirs — ideal for drivers who want one knob to tune, or race classes that prohibit canisters.

Moton splits the G8X by driveline: rear-wheel-drive cars (M2, M3, M4, M3 / M4 Competition RWD) and xDrive cars (M3 / M4 Competition xDrive) use different part numbers and are not interchangeable. Select your driveline from the Application menu above.

SPECS

• Monotube damper, non-inverted, 1-way adjustable (rebound) with 15 click positions
