1990–1997 Mazda MX-5 Miata Suspension & Handling FAQ's

Please read our FAQs page to find out more.

What coilover spring rates work for a dual‑purpose NA?

Common street/track rates are ~7–9 kg/mm front and ~5–7 kg/mm rear with digressive damping. Add front camber (‑2.0°+) on 200‑TW tires to protect shoulders.

Do sway bars reduce body roll without hurting ride?

Moderate bars control roll; avoid oversized front bars that induce push. Balance with alignment and rebound settings to retain compliance on bumpy roads.

Should I add chassis bracing on an NA?

Yes—front subframe braces, frame rails, and a butterfly brace tighten the 30‑year‑old tub, improving steering precision and reducing cowl shake.
