What would that require aside from the hitch?

I am still not sure of the design yet. Maybe it will be something beefy that stays on the car once installed or maybe something that can be removed to avoid any extra weight on track.

One thing for sure is that it will not involve any modification to the chassis.

This.

ETA: It doesn't need to be completely removed - just a good compromise between weight and time. The Westfalia trailer hitch allows the heavy tongue to be removed easily but leaves (est.?) ~25 lbs. on the car. For most of us - we can make up for this with an even lighter battery etc. Time in the paddock either arrival or departing is limited - so it needs to be a balance of weight/time.

A hitch would be the way to go with a tire trailer IMO.

Something like Paco makes for Miata's would be awesome. I'd be 100% ok with 10lbs on the light end of the car if it meant I could pull a small trailer.

Yup me too. Even if itís a small trailer that can only hold 1-2 wheels.
