NC Roadster NCEC KONI SPORT + Flying Miata Lowering Springs, Front/Rear Set, ~20k km
NC ロードスター NCEC KONI SPORT+Flying Miata ダウンサス 前後4本 減衰調整 約2万km

This is a used front-and-rear coilover set removed from a Mazda Roadster NC (NCEC), consisting of 4 KONI SPORT (KONI Yellow) shock absorbers paired with Flying Miata lowering springs for the NC chassis (2 front, 2 rear, marked FMSNCFRONT and FMSNCREAR). The kit includes upper mounts, 2 damping adjustment knobs, and KONI's instruction manual. According to Flying Miata's published data, this KONI SPORT/spring combination yields a ride height of roughly 343mm front and 330mm rear (wheel center to fender arch), which the seller estimates as about a 4cm front and 5cm rear drop versus stock on an early 2005 NC Roadster; actual drop varies with grade, equipment, spring sag, and wheel/tire setup. The parts were used for approximately 20,000 km, then removed and stored long-term. The seller cannot guarantee current damping performance, shock seal condition, oil leakage, or the state of bushings/upper mounts after long-term storage, and recommends inspection/maintenance before use.
Seller notes scratches, dirt, paint peeling, rust, and dullness from use and long-term storage; damping performance, possible oil leaks, and bushing/mount condition are unverified.
