Got my 16 SE MT a few weeks ago. Since then I've installed a raceseng shift knob, installed clutch stop, clutch spring delete, solid shifter bushings, shift linkage alignment, and clutch delay valve delete. The MT is a totally different animal now. I haven't had a ton of time to drive around, but so far it's awesome. Getting rid of that delay valve is easily the best thing I've done, highly recommend it to anyone not pumped about their MT. I didn't have the shifter alignment pin, so I used an Allen wrench. It allowed more play than I think there should have been, so I ordered an oem alignment pin and will redo the alignment when it gets here in a few days. It shifts just fine, but is a little notchy and not as smooth as I think it could be.
What did you not like about the MT before? This is my first MT and the thing that bothers me the most is how I can never shift into second gear without some crunch or resistance. Curious what mod I'd need to do to correct that.
