    After installing the CMAK kit with the os giken TR2CD the car’s clutch engagement and feel has drastically improved greatly. Not only does it almost retrain OEM clutch pressure feel it also gets rid of that sloppy soft mushy clutch feel the OEM has. It feels very direct now and much more enjoyable in driving feel. If anyone is worried about clutch pedal becoming too hard I would not worry about that it is just slightly stiffer then OEM and very street-able. I only wish I’ve done this mod years ago.
