Installed an extended clutch stop today to eliminate the dead space at the end of the clutch travel.
Initial impressions are it totally transforms the shift sequence. It seems like a small thing but the difference is kind of surprising.
Original reason I got it was actually for pedal positioning. I've always adjusted my seat so that my left leg can hit the clutch to the floor while its 90% extended. However to do so, meant my right leg was a bit cramped on the accelerator + brake. I've always thought this might be why I've had aggravated back pain after driving the car for extended periods.
Anyways, really happy with this so far after the 5 minute or so drive! Worth doing and in theory, should make shifting much more direct and quicker.
For some comparison, when I drove my friend's BRZ, I told him the clutch felt really direct and "button-y". Sort of on/off bam-bam but I didn't know why. Seems that the dead space may account for some of that as I'm getting that same feeling.
Tis a positive thing for me 8)
Sorry for the crummy pic!
The one I got from a local seller didn't come with a locking washer - though I've wound it in as far as it will go and it's gone TIGHT so perhaps not needed. I'll try and find one regardless just to complete the job and probably a washer for neatness around the carpet.
One thing to note the padding on the stop is a bit spongier than OEM - not sure how i feel about that but easy to change later.
