DIY Racer Swap Kit

  • The only significant difference with our new low cost flywheel adapter is that it is not a bolt-on solution like our normal adapter. This new version requires the end user to modify their existing Miata flywheel. Don't worry, no machine shop or specialty tools required. You'll need a drill press, and a 7/16” drill bit. Instructions are included with the kit. This is essentially the same piece we have been running on our race car for two years.
