HKS Hipermax IV GT 20SPEC Coilovers - VAB WRX STI / VAG WRX S4

This is a full set of HKS Hipermax IV GT 20SPEC coilovers, a limited variant of the well-known Hipermax IV GT line tuned for a more compliant ride while retaining Subaru handling characteristics. The kit is full-length adjustable (front and rear) with 30-way damping adjustment. Spring rates are 88 N/mm (front) and 69 N/mm (rear). Approximate lowering range is -19mm front / -14mm rear on WRX STI (VAB), and -21mm front / -16mm rear on WRX S4 (VAG). Primary fitment is VAB WRX STI and VAG WRX S4; the seller notes it may also fit VM4/VMG Levorg and GRB Impreza with modification, though direct bolt-on fitment is not guaranteed for those applications. This is a complete set for one car (front and rear). Only the parts shown in the photos are included — wearable items such as rubber bushings, boots, bolts, and nuts are generally not included and should be sourced separately if needed.

Seller grades this B, excellent condition, used for roughly 4,800 km with no bending or oil leaks; shocks compress and rebound properly and the lower seat, shell case, and damping dial all move freely with no seizing.

Shipping: Ships via Sagawa Express. The seller does not offer combined shipping with other items and does not offer local pickup. Cash-on-delivery is available for an additional 440 yen fee if selected.
