7MT clutch full in
 
Do you press the clutch full in for every shift or just below the engagement point, is there any harm on the clutch if it's not depressed all the way to the bottom during shifting?

All the way bud. If you don't take the pressure off the plate, you add a little more stress to the system (throwout, etc), and that transfers to the trans. The second gear cold grind is a good example. If you FULLY push the clutch in, you'll notice far less of it.

You can certainly do it if you get past 'the point', but you're better off hitting the floor and knowing.

The answer to your question is no, there is no harm to the clutch if not pushed all the way to the floor, as long as the clutch is fully disengaged when you shift. The problem when trying to shift that is it's very difficult to know exactly when fully disengaged unless you feel it hit the floor. I've experimented with this method for shifting and for me it just is not difficult to get it right overtime unless I get very near, or to, the floor. You can shift without harming the system though,, without pushing all the way to floor.

I've noticed that when I push mine all the way to the floor it jerks upon release. If I just push in until I feel the gear release it engages smoothly.

You should be able to feel when it starts to engage when releasing the petal. When you shift make sure your petal is below that point. Never in 60 yrs have I put the petal to the floor. Only time is when starting my C7

So it comes down to theory vs practice. Is there any harm as long as the clutch is in fact fully disengaged? No. Can you burn the clutch if you don't get it right? Yes.

My BMW M3 has an adjustable clutch stop. It physically prevents you from pushing the clutch further than required. And it's adjustable to compensate for clutch wear. So the clutch starts to bite IMMEDIATELY, (ok, .005" of movement) It works quite well.

I've never seen the need on the C7.. Mine seems to start biting right off the floor.

Full-in minimizes chance of excessive clutch wear and synchro wear. There is no extra wear to the clutch system due to pushing the pedal to the floor.

Clutch pedal? We don't need no stinking clutch pedals!!!!!!

I knew a girl, whose husband was a truck driver. She could shift a stick without the using the pedal - it was amazing!

Agree the clutch in my M3 had higher engagement point than the stingray, i like the stingray clutch better

Did consider clutch stop for M3 but never did it for fear of warranty issues
