Japanese Subaru Technica International (STi) has developed and homologated a R4-kit for Subaru Impreza WRX STi N-5714 and N-5732 rally cars. The R4-kit increases the competitiveness of the group-N Subaru Impreza WRX STi compared to Super2000 cars.

R4-kit further improves on the already fast group-N Subaru Impreza WRX STi´s performanceand reliability. For example it reduces the car's weight by approximately 50 kilograms, has stronger lower bottom arms with uniball and also increases the car's suspension travel for smoother and accurate functionality.

R4-kit classifications were homologated 1st of May 2011.

Tommi Mäkinen Racing strongly believes R4-kit will improve your rally results.
