Folks,
We ran SC in 2014 and absolutely loved it. We ran dirt only for a variety of reasons, which are outlined below:
1). Licensing - At the time (as memory serves) there was a "Dirt Only" license which offered a small discount. It wasn't much but every dollar counts.
2). Not only are different tires required between dirt and pavement but different front wheels and different right front hubs are required due to the additional load the RF experiences on pavement. While we could have used pavement RF hubs on the dirt, we used what we had, which is direct mount sprint hubs.
3). On dirt you can get away with the standard sprint car brake system, with minor changes. On pavement the brake system needs to be more robust due to the additional braking necessary.
These are only a few of the items that differentiate dirt from pavement racing. While USAC could change the rules to mandate using the same "car" for both, rule interpretation and enforcement would be, in my opinion, next to impossible. First, we have to define "the car". Is that only the chassis, or does it include the rear end/driveline/front axle/right side vs left side steering, brake system, .... As you see this can be daunting. And please understand, many of the differences between the pavement and dirt cars are derived from safety concerns due to the different loads the cars experience between the two.
So this is why we decided on dirt only and I believe there are others who are in our same boat, from an expense standpoint. While we sold our car this year I am contemplating getting back into it. If I do, I'm seriously contemplating equipping ourselves for both surfaces just to help bolster the car counts in an effort to get and keep SC healthy.
