2023 ST/TT Car Classification Form is Live

We have updated the ST/TT Car Classification Form to reflect all the 2023 season rules. 

You will need to submit a new car classification form for 2023 competition season. Once you have submitted your car classification form, it will appear under your specified region. It might take up to 10 minutes for the system to process the request. You will also 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.

Important points to remember regarding the classification form and Dyno reports:

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' 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. 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 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.

5. Certified Dyno reports are potentially valid for up to a maximum of three years (provided that no changes have been made to the vehicle that would alter Dyno readings). However, at his/her discretion, a NASA ST Leader may require an updated certified Dyno report (at the driver/owner’s expense) after one year from the date of the previous report.

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

 

Happy New Year and have a Safe, Fun, and Healthy 2023 Competition Season!

A bit of a nit...

The Nankang CR-1 was renamed to the CR-S last year.  Same tire.

Turns out there was another tire out there with that name in another market (overseas SUV tire).

IS the Fat car rule for tire size going to be applied? I believe it was over 3750# didn't take the >315 penalty but I don't see that on the form, or do we just leave it as "not Applicable"  May confuse some competitors if not spelled out on the form

The form will not allow to submit if the weight is over 3750 and the 315 mod factor is taken.

The st4 section won’t let me select a tire width category on mobile. 

What weight is your car?

I’m a TT newb and considering TT4 with a comp weight of 2740. Noticed some categories on the classification sheet are already checked ‘Not Applicable’ including Tire Type. Are we supposed to indicate our tire choice or leave that category marked Not Applicable?

Hi! Welcome to TT!
You should make a choice from the three tire type categories - unless you're not running any of those tire types, then select "Not applicable".
The "Tire Size" is not selectable for you as 266mm section width is the maximum for TT4 for vehicles under 3000lbs.

Correct.  We added it to the rules last year, and looks like it didn't get transcribed to the calculator.

Hello.  I noticed that when I print out the completed classification form it omits the "Brakes" mod section.  The correct Total Mod Factor is maintained.  I'm a TT5 driver and I don't know if this is only happening to my class and not others.

Form has been updated to reflect the latest technical bulletin. If you are effected by the technical bulletin, you can edit your form and select the proper modifier that fits your Tire Type. An updated form will be emailed to you.
