Why Do We Call Our Sprint Car Inboard Rotors the VRT Max 72?

Well … VRT = vented rotor technology. Max 72 = it has 72 vent holes. Plus that – it sounded cool. Since we’ve named it, we’ve improved it. The sprint car inboard titanium rotor now has more holes to help the heat escape and give it better air flow, keeping it even cooler. This is the lightest and strongest sprint car rotor available in the industry! Drivers using this rotor won the 2021 Kings Royal, the Knoxville Nationals, the Jackson Nationals, and 10 out of the 13 World of Outlaws events so far in 2022. Here are the specs:

Size: 12.200″ O.D. x .350 thickness
Made from aircraft titanium 6AL4V
Surface ground flat on both sides
SUPER LIGHT! WEIGHS ONLY 3.25 lbs!
Dimensions: 12.200″ x .350
