1999–2005 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 NB?

Common street/track rates: ~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 ruining ride?

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

Should I add chassis bracing to an NB?

Yes—frame rails, butterfly braces, and front subframe braces tighten the tub and reduce cowl shake, especially on convertibles.
