Product Details
The BLOX Racing Street Series II Coilovers are the street-tuned full-bodied coilover system for the 1990-2005 Mazda Miata (NA/NB). 7/7 kg/mm spring rates and purpose-tuned twin-tube damping give the NA/NB Miata a comfortable daily ride, adjustable stance, and enough performance headroom for spirited weekend driving. It's the daily coilover of choice for owners who want a step above lowering springs without committing to a stiff track setup.
Every set ships with fixed-damping twin-tube shocks, 7/7 kg/mm springs, height-adjustable spring perches, included top mounts, dust covers, bump stops, and a spanner wrench set. BLOX has pre-tuned the damping for a balance of street comfort and sporty response — no knobs to adjust and no compromise for daily drivers. If you're stepping up from lowering springs or tired factory struts on a NA/NB Miata, the Street Series II is the honest coilover upgrade that doesn't punish you on long commutes.
