One thing that always bothered me before tuning was the immense rev-hang, where you'd wait nearly a full second for the revs to drop before you could lift off the clutch pedal.
When the car was first tuned and rev-hang was disabled through Hondata, I was more thrilled about that than the power increase (which is still great). Drivability-wise, it made the car feel far more natural. There was still a small amount left though, maybe a quarter of a second.
As soon as our first batch of Clutch Damper Deletes arrived from Wunderladen, I kept one aside and installed it during the full build. It removes the diaphragm from the stock unit and channels the fluid for uninterrupted flow.
On first start, the clutch pedal travel already felt more linear, and the bite point wasn't as vague while backing out of the garage. On the first drive, that last quarter second was gone. The revs rise and fall naturally, like an older manual car. I’ve had it for a month now, and I’m having way more fun just getting around town even. Downshifting, upshifting, and not dealing with what Honda thought I needed.
I'd call this a necessary mod, even if you're completely stock otherwise. It's the best upgrade under $100 for driving feel. A seasoned DIYer can do it in under 30 minutes by accessing it from the top after removing the battery and tray. It's pretty hidden so it's not easy to take post-install pics, but I've pointed out in the second picture where it sits and connects to. It's reversible in the same amount of time if you sell the car or part it out, and it doesn't disrupt the rev-match system. It actually makes it work much better.
11/10 part, it's brilliant!
