Challenger Series
Challenger Series
Challenger Wheels are Lightweight – “Competitively Priced” – Spun Shell wheels with a round hole center. This wheel out performs the rolled shell wheel without the premium spun shell price. The .095” thick spun formed shell mates with a center, which is draw formed and stamped to create a strong, lightweight and affordable racing wheel ideal for asphalt racing. Dirt racers will want to add the optional safety beads to keep the tire “locked” onto the wheel. The Diamond Challenger Series is an ideal choice for road race, solo and auto cross races running 14″ tires. Many bolt circle choices are available. Gloss black powdercoat finish is the standard stocking color. Chrome looking Silver powdercoat finish is also available. Chrome Rim/Raw Center (you paint center) only available in 15×8 and 15×10.
