Coilovers for Mazda Miata / MX-5 (NA, NB, NC, ND)

Mazda has built four generations of the Miata/MX-5: NA (1989-1997), NB (1998-2005), NC (2006-2015), and ND (2016-present). Coilover manufacturers typically sell NA and NB as one shared fitment, since both chassis use the same front and rear strut mounting points, then move to separate SKUs for NC and ND. The table below lists current kits from Godspeed, BC Racing, and Fortune Auto pulled from manufacturer and retailer listings, with the exact source linked for each row. See the full by-car fitment list and brand overview for other platforms.

Drop on a Miata coilover kit depends on the spring rate chosen, corner weight, and how far down the owner threads the lower perch - it is not one fixed number for every kit. Entry-level kits for the NA/NB, NC, and ND chassis commonly ship with front spring rates around 8-10 kg/mm and rear rates around 6-8 kg/mm, based on the manufacturer listings above; stiffer rates are sold for track-focused builds. Because the usable drop range for a specific kit is set by the manufacturer and can change between revisions, check the current listing linked in the table before ordering, and see our guide to adjusting coilovers for how ride height is set after install.

Any ride height change on a Miata alters camber and toe, so budget for a full alignment right after installing coilovers, and again once the springs have settled over the first few hundred miles. Owners running a noticeable drop on the NA/NB and NC chassis often add adjustable front camber plates to pull excess negative camber back into a usable range, and the ND tends to need the same correction once lowered more than a couple of inches. Lowered Miatas on stock-width wheels rarely rub at the fender since the car's footprint is narrow, but owners running wider wheels or more negative offset should check strut-to-tire clearance through full steering lock before settling on a ride height.

The NA and NB share a chassis platform closely enough that most brands, including Godspeed and BC Racing, sell one coilover kit across both generations. The NC is a heavier, stiffer chassis, and Godspeed's own listings show it running a lower spring rate than its NA/NB kit (8 kg/mm front and 6 kg/mm rear on the NC MonoSS versus 10 kg/mm front and 8 kg/mm rear on the NA/NB MonoSS), reflecting the different factory suspension geometry rather than a simple carryover. The ND, Mazda's lightest Miata since the NA, lands on the same 8 kg/mm front / 6 kg/mm rear rate as the NC in Godspeed's lineup, but uses its own part number and top hat design, so NC and ND kits are not interchangeable even where the rates line up. Specialty retailers such as Flyin' Miata also sell generation-specific coilover packages built around this same platform-by-platform split.
