I would have to say that the carpet kit generates a lot of rear grip , especially with a ball diff. I use it even indoors on shiny surfaces as the car he much more steering than the dirt car. Certainly on dry Astro of any grip level the carpet car will be best. However, if you are thinking you will be competing in wet weather much, then the dirt car is the way to go. Imo the dirt car in the uk is basically a wet car only. It really lacks corner speed and steering in the dry compared to the carpet car.
