Here's a link. http://www.burgertuning.com/clutch_stop_BMW.html I took one of the pads out, feels perfect for me, but easy to change and install. No more high clutch.

Try keeping your left heel on the floor while working the clutch. It gives you another point of contact, allowing for more precise modulation. It works well for my size 13 feet at least

Does the clutch stop cause any premature wear on the clutch? Makes me wonder why BMW just didn't make it "short throw" to begin with? I mean these are performance cars after all!

No premature wear as the clutch stop will still allow you to fully depress the pedal past the disengagement point.

Great question, i very much think so and hence the reason didn't get it.

How does depressing clutch beyond engagement point help in preventing clutch wear? You are lowering the engagement point using clutch stop which is not the optimal point per BMW for clutch wear and tear

I also don't think BMW or a a big manufacturer would keep the engagement/disengagement window for the clutch and flywheel that close to either end of the pedal travel.

I have been driving manuals for 35 years with 20 different cars. I have never experienced the "bucking" feeling on the 1-2 shift in any car like I did in my test drive in a 2019 M4 manual. I was set on getting the 6MT, but I don't think so much effort should be required just to get a smooth shift from 1-2. Test driving a DCT tomorrow.

After having my M3 for 5 months i've learned to prevent the bucking either by shifting 1-2 with the rpms below 2500 during moderate driving or just wait a second for the rpms to drop/hold before releasing the clutch. During max acceleration you need to have it in at least MDM mode because when traction control intervenes it can feel like its bucking when its cutting power.
My brain is trained for this now so it becomes automatic. It makes the 6MT more special and an "event" to drive for me Alan

I used the BMS clutch stop for 6 years in my F30 with no ill effects. I transferred it to my F80 and never looked back. Besides practice and patience, I think that the best advice here is just to use 1st to get the car rolling and then use 2nd to really launch it. Trying to get the most out of 1st gear is actually counter productive if the goal is a smooth launch. My $0.02.

I,too, experienced this. I noticed if I shift at higher revs, the problem doesn't surface. I also noticed that this problem decrease as I put more miles on it, but I also have changed my MT fluid.
I also get a audible thud once I initially start rolling. I always believed it's the brake pads bonding with the rotors from rinsing the are. |

I think after all of this I've come to realize that its not the shift itself that's not smooth, is getting back on the gas. If I shift first and then don't give more gas, its smooth, adding gas is when it can get jerky. I think the throttle response is just too sensitive in 2nd gear at low RPM. Not as bad in Efficient mode.

Clutch stop made all the difference for me. Before I felt that the clutch wouldn't allow for quick shifts as the clutch engagement was too slow. I wonder if this is the OEM design so that the transmission is protected and not abused?

I took a test drive in a new M4 manual with a BMW factory rep today and he confirmed the 1-2 shift issue is the rev matching feature that makes the car "buck" between 1-2 shifts. To shift smoothly he suggested I start off in 1st and shift into 2nd gear in the 5-10 MPH range. Since the car has a long 2nd gear, full throttle would start in second gear and would accelerate nicely due to wide torque band. Not exactly my idea of spirited driving using a manual trans in an M4.
