Corsair C10 is designed for road race use and is the wheel of choice for many Pro SCCA and IMSA performance builders. Each C10 is put through a finishing process known as "shotpeened" at no additional cost to the customer. This gives the wheel a raw machined classic race look. The extended back bell and narrow drop center of the wheel fit of large diameter performance big brakes. Monoblock construction forged from 6061-T6 aluminum results in extremely lightweight forged racing wheels. All designs pass a 3000 lbs. (per wheel) cornering fatigue test load at 200,000 cycles.
