Product Details

The BLOX Racing Drag Pro Plus Series Coilovers are drag coilovers for the 1988-1991 Honda Civic Si (EF). Engineered specifically for the EF Civic Si platform, the Drag Pro Plus system pairs 24 levels of damping adjustment with purpose-built 12/18 kg/mm spring rates to maximize launch traction, lower 60-ft times, and improve high-speed stability. For 1988-1991 D16A6 Honda Civic Si builds chasing faster quarter-mile ETs, the Drag Pro Plus is the serious drag-duty coilover upgrade.

Every kit ships with 24-level adjustable struts, specifically weighted front and rear springs, pillow ball upper mounts, adjustable billet aluminum lower mounts, dust covers, bump stops, and a spanner wrench set. Dual ride-height adjustment (independent spring-perch and lower-mount heights) preserves full shock stroke at aggressive ride heights. Whether you're running all-motor D16A6 or a boosted build on the EF Civic Si, the Drag Pro Plus geometry is tuned to put the power down.
