Fitted to: R-Tune, Customer Cars



R1 is ultra-precise tuning that combines high-performance parts and skilled mechanic technology. Demonstrating an overwhelming power feel in the medium to high speed range that is frequently used in circuit driving, while ensuring easy-to-handle torque characteristics. Furthermore, in consideration of use under hard conditions in each stage of the circuit, development was made with emphasis on durability.

Reinforced parts such as N1 specification engine block, piston, piston ring etc are used in order to increase the engine durability to a level that can cope with a large increase in output in the high rotation range due to high load and large capacity turbo during circuit driving. Furthermore, the R1 exclusive ECM and exclusive camshaft were used to pursue the best circuit characteristics. In addition, in order to resolve daily complaints about high-power engines, the company has been working to ensure a certain level of ease of handling on the street and has cleared laws and regulations.
