What you need to know
Measure the straight bar section with calipers and match axle, generation, option package and bar manufacturer. NA/NB front-link geometry differs; Racing Beat specifies 54201 for NB front while 54200 covers NA front/rear and NB rear. Inspect brackets, mounting flanges and holes. Set adjustable links without preload at ride height and preserve adequate thread engagement and suspension clearance.

No universal supersession chain is claimed. The listed OEM bars and bushings are application/option branches. Match the installed bar and measured diameter; do not convert a family list into an interchange claim.
Fitment
Measure the straight bar section with calipers and match axle, generation, option package and bar manufacturer. NA/NB front-link geometry differs; Racing Beat specifies 54201 for NB front while 54200 covers NA front/rear and NB rear. Inspect brackets, mounting flanges and holes. Set adjustable links without preload at ride height and preserve adequate thread engagement and suspension clearance.
Aftermarket options
Checked paths include diameter-specific bushings, Racing Beat 54200/54201 adjustable end-link pairs, Advanced Autosports NA/NB link options, AWR bar kits from Planet Miata, and generation-specific Flyin' Miata links. Aftermarket bar diameter and geometry may differ from stock; match the actual bar and mounting layout rather than ordering by model year alone.
Before you buy
There is no universal NA/NB sway-bar bushing or end link. Match generation, axle, factory option or aftermarket bar, measured straight-section diameter and bracket condition. NB front uses different checked adjustable-link geometry from NA front/NB rear. Install links without preload at ride height and verify thread engagement and clearance. Seller prices and availability are dated observations.
