Solid Delrin transmission mounts for your 86-91 FC RX-7. Replace your warn out & sagging OEM rubber mounts. All mounting hardware included, all you’ll need is the tools to install.
We have these on our project ’88 T2 swapped vert, and don’t notice a difference in road vibration, though launches are felt a bit more. Recommended for any and all race cars/cars you can live with an ever so slight “discomfort”.
