Ikeya Formula was started in 1996 in Atsugi prefecture which is situated right out side of Tokyo. With the help of some of the highest technology robots and machinery, Ikeya Formula has been able to develop an extensive line-up of extreme footwork parts and are famous for their one of a kind sequential shifter. These products have been driven to the extremes and have proved to be durable enough and provide more adjust ability than similar products from other manufacturers. Many of the Ikeya Formula parts have such an advantage that almost all professional D1 drivers have at least 1 piece of equipment from Ikeya Formula on their machines. Ikeya Formula's Japan website
