Edit.
Rear suspension metallic clonk - #3 by Woodford.

Might work for an NC too.

NC Rear Suspension Banging - what to check next?

Hi All, First post here so hope I get everything right, apologies in advance if not. My model of MX-5 is: 2011 NC (MK3.5?) I’m based near: Bath I’m looking for technical help or recommendations on: Rear Suspension I’m after some advice on what to check next on the (all standard) rear suspension, which is making a banging noise on both sides whenever I run over a bump. I’ve replaced the drop links and ARB bushings but am still getting the banging noise. Oddly it seems to get worse when warmer…
