Rear anti-roll bar bush. Mazda MX-5 & Eunos Roadster mk1 1.6 all models with 11mm anti roll bar. Genuine Mazda part. 2 required.  If your suspension is starting to feel a little less taut than it ised to, try changing these bushes before spending out on shocks and springs.

Note that the 11mm anti roll bar was only fitted to the early mk1 1.6 models from 1989-93 with standard (ie. not Bilstein) suspension.
