Product Details
The BLOX Racing Street Series II Plus Coilovers are an all-around suspension upgrade for the 1990-2005 Mazda Miata (NA/NB). 7/7 kg/mm spring rates and 32 levels of twin-tube damping adjustment deliver a comfortable daily ride on the NA/NB Miata while still offering the adjustability to handle weekend canyons or an occasional track day. Included top mounts make this a complete, bolt-in upgrade — no extra parts needed.
Every set ships with 32-level adjustable twin-tube dampers, 7/7 kg/mm springs, height-adjustable spring perches, included top mounts, dust covers, bump stops, and a spanner wrench set. Aluminum shock bodies resist corrosion for year-round use, and the wide damping range lets you fine-tune the NA/NB Miata for commuting comfort during the week and firmer canyon or track duty on the weekend.
