Tailored Chassis Solutions (TCS) built this second generation Honda Fit to compete in American Endurance Racing at their company in Millbury, Massachusetts. The car comes from the factory with a 1.5 L L15 inline-four however TCS swapped it for a 2.4 L K24Z7 inline-four from a 9th generation Civic Si using Hasport mounts. Power is sent to the front wheels through a six-speed manual transmission also from a 9th generation Civic Si. The car rides on a set of BC Racing coilovers with 255/40-17 tires in front and 225/45-17 tires in back. If you are interested in more displacement in your Honda Fit, TCS provides turn-key K-series swaps along with upgrading the suspension and brakes.
