I been driving manual transmisson for 15 years now, I consider my self a good driver and has a some track experience. I had much powerful car than Si before. But for some reason I feel like when I drive the Si hard I really need to pay attention when shifting gear, I changed my tranny fluid allready with amsoil so I don't grind 3rd gear anymore. Is it just me or I'm not paying attention when shifting? that's why I miss shift like once a month. Is the stock clutch don't go in that quick, because this is my 1st (manual) new car so I'm used with act clutch, all my previous cars before have act clutch and lightened flywheel.
