D2 DRIFT Series suspension kits provide you with ultimate control over your drift 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.
