Enkei GTC 01 Enkei has been racing in top competition championships of the world for three decades. As a result of continuous improvement and technological advances, Enkei continues its winning tradition and constantly challenges new horizons in wheel technology. Enkei GTC 01 has a light weight pocket design, an innovative technique that was created for the McLaren Mercedes Formula One Machine. Shaving aluminum from the sides of the spokes relieves wheel stress and makes the wheel lighter. Enkei GTC 01 also utilizes anti-slip paint on its wheels, which it turns causes high friction where the wheel meets the tires while reducing wheel spin to the tire during extreme acceleration. The Enkei GTC 01 comes in Hyper Black and is available in 17 inch, 18 inch, 19 inch, and 20 inch sizes.
