D2 Drift Series suspension kits provide you with ultimate control over your drfit when you need it most. These coilovers feature an inverted monotube strut design and 55mm pistons which allow them to maintain peak performance under extreme conditions while maintaining 36-way adjustability. Specially designed mounts, helper springs, and drift-spec spring rates with matched valving result in a high performance coilover that is the standard for many of todays top drifters.
