This is a pair of optional HPI Racing Molded Inner Foams for the rear of the Baja 5B line of 1/5th scale buggies. These are molded foam donuts that help support the tire for stable performance. The “MS” compound is firmer than the stock foam donuts, giving the steering a precise feeling when making sharp steering transitions. Sold in pairs. These are for use with the 170x80mm HPI tire.
