FRONT MOUNTED R2 COMPOUND (pr)

“R” series foam is a slightly different blend than the “X” series. The “R2” is sometimes better than the X2 on very wet clay. In other situations the R2 can be used to unstick the car in spec classes compared to the X2. Use firmer compounds if track is abrasive or to get the car to roll more freely and slower spec classes.
