Urethane engine mount spacers made for the 1.5L and 2.0L ND MX5 Miata. It’s made to improve the shifting feeling and prevent mis-shift during racing. The hard rigidity version will add slight vibration at idling, but will improve shift feeling more. The soft rigidity version will virtually not add any vibration (just slight one during fluctuation of the engine) and improve shift feeling and comfort. Please note that one picture shows the product and the other picture shows the product installed.
