A $1,000 Miata coilover budget is not one universal product category: NA/NB (1990–2005), NC (2006–2015), and ND (2016+) kits do not interchange. Start with the chassis, then compare spring rate, damper adjustment, ride-height range, top mounts, and the cost of alignment and installation. The list includes exact-platform kits sold at or around the cap; pricing moves with sales and availability, so treat the range as the buying screen, not a promise. Very low spring rates and aggressive drops can compromise travel and geometry, while a better damper can matter more than a bigger adjustment-count number.

- ND 2016–2022 fitment
- 5.5 kg/mm front (308 lb/in)

Buying tips
- NA (1990–1997), NB (1999–2005), NC (2006–2015), and ND (2016+) are separate fitment families. Verify the exact year and part number rather than relying on the word ‘Miata’ in a listing.
- Budget for a professional alignment after changing ride height. A coilover purchase that leaves no money for alignment, worn bushings, or tires is not really a $1,000 suspension plan.
- Near-miss context: TEIN Flex Z NA/NB listings and higher-tier systems can exceed the cap depending on seller and stock. They are not interchangeable with a sub-$1,000 promise merely because a sale or used listing exists.
