NASA has updated the ST/TT Car Classification to reflect the new year. No other changes were made for this year.

Instead of submitting a whole new form this year, ST and TT competitors have an option to edit their 2020 form via the link, which was emailed to them and verify that all of modifications and dyno information are still current, and to update them as necessary. The dyno is good for three years from the time of the official test.

Once you have updated your submission, it will appear under your specified region. It might take up to 10 minutes for the system to process the request. You also will receive an email with the PDF version of the form, which you can print and give to your ST/TT leader along with your dyno compliance paperwork.

If you have lost your Edit Link to your form, you can request it via the process outlined in the NASA Forums.

Some notes on the changes to the form from 2020:
1. The form only asks for Minimum Competition Weight input. The Max Average Horsepower (Max Avg HP) is calculated automatically based on the class selection and the Total Mod Factor. This is done to get you as close as possible for the class’s Weight/Power ratio. The Declared Max Avg HP is always rounded down. This way the calculations are always in compliance.

2. The form might recommend a lower weight for the targeted Max Avg HP because the calculations round down the Declared Max Avg HP. Please note that the Recommended Minimum Competition Weight does not account for the weight factor change in the final calculation. So if you are on the borderline, the Recommended Minimum Competition Weight, if used, will change your Declared Max Avg HP.

3. Each submission will have its own folder with all the uploaded documents in the Airtable. Each time you edit the form, new attachments and a new form will be uploaded to the Compliance Docs folder. Everything is time-stamped. One folder will contain all the current and past submissions for your car.

4. The latest ST/TT form for your submission is linked in the new column called “Latest Form” in the Airtable.

Make sure to leave some room for dyno variance by increasing your minimum weight if needed.
