2017+ HONDA CIVIC (Si/LX/EX/Touring) / TYPE-R Cusco Parts List

Updated: May 25, 2018

2017+ HONDA CIVIC & Type-R Cusco Parts List

You asked for it! And it took us a while to collaborate with Honda, and figure out what and where we can enhance the fine-tuned character when used with higher grip tires and on a raceway specifically...
And here it is folks!
In addition to working with data Honda provided, we have toiled many kilometers in lapping various raceways of Japan and on canyon roads over and under Japan.  To tune it with our rally and track drivers and seek further enjoyment of Civic Type R's.
We sought to keep the excellent total balance of the car for use with more aggressive tire choices, and harder, faster end of performance threshold.
These parts are the results of Cusco's engineering team with long experience in racing since 1977.
