I can tell you that the racing in 2wd and 4wd Mod has been very competitive at McCullough's lately. The last two weekends of club racing we've had 14 buggies in both classes. Traction at McCullough's is usually very high and we normally run pink taper pin slicks with buggy grip. Sometimes if the track drys a little, we run regular pink taper pins with a softer foam. Hope to see you all at the ROAR race...
