Racing is where all of the best R&D happens. Engineers obsess over every detail looking for the slightest advantage to shave fractions of a second off of lap times. That’s how the new Enkei GTC02 was born. Based on the RA series wheels used in the Super GT racing series, the GTC02 pulls from the same bag of tricks as the RA series to give weekend racers the competitive edge they need to win. Utilizing a 6 split-spoke design that disperses stresses efficiently allows us to keep the spokes as thin as possible and make cuts in them on the fronts and sides to shave weight even further. The GTC02 is available in sizing ranging from 18×8 to 19×10.5 in a wide variety of PCD and offset configurations to fit most modern sports cars. Sizes 18, 19 Hyper Silver or Matte Black MAT Technology Spec-E Inspected Created with MAT Technology (Most Advanced Technology), a new manufacturing process or aluminum wheels, which drastically improves the material property and strength of the wheels. Shaping the wheels using the MAT process reduces wheel weight by up to 15%. This allows you to reduce the overall weight of your vehicle weight by 20lbs. Rim-Rolled technology shapes the rim to improve material elongation without sacrificing the wheels.
