Got to drive the 1st gen 86, and I think the clutch might have been better in that one

I have always just assumed that every manual requires you to ride the clutch quite a bit to get smooth shifts from 1-2 and to a lesser extent 2-3, but dang the old 86 clutch made it a cakewalk. The length you have to push in to clutch in is way shorter for starters, felt like half as much as ours. Shifting was just incredibly easy in it, like comically. You barely had to think, just foot down, shift, foot up. In the current gen, its a bit of an art to do and every person I have let drive it has those classic jumpy/jerky shifts in it when doing 1-2, including my buddy who owned the old 86.

Anyone else here have this experience too? I think Toyota might have made a mistake with this current gen clutch.

After waiting, literally, for. months so that I could get a manual transmission, I have to say I am not overly thrilled with the driving experience for most of the reasons listed above. The clutch engagement point on mine is great, but it such a damn chore to make a smooth shift! From what I understand the issue is most likely the factory "helper" spring tension. I am very tempted to replace that spring with one of the aftermarket alternatives to see if it will help. What's weird to me is why this spring is necessary to keep the throwout bearing from wearing out. I have owned literally dozens of manual transmission cars over the years that did not have one of these springs and those cars didn't have that issue. So what gives, Subaru/Toyota? Side note: I have found that the shoes I wear really make a difference in how smoothly I can drive my car. Thick soled tennis shoes are not so great. Flip flops are useless. Thinner soled tennis shoes or proper driving shoes definitely help.

3 things to fix this:

1) Pedal commander (or similar throttle lag killer). The throttle lag is partly what makes smooth shifting a chore.

2) MTec spring

3) Pedal travel adjust since many like the clutch bite point to be closer to the bottom of the travel. There are two ways to do this. The first is to lower the pedal further to the floor. This method will require changing the clutch position sensor if you lower the clutch past a certain point. The second way is easier and does not require sensor adjust: get some furniture felt pads and stack em up on top of the clutch stopper screw until the full travel is just beyond the bite point.

This way the predictability will be much greater from all components working together.

The helper spring makes the pedal easier to push on the way down, but on the last inch or so on the way back up it forces the pedal all the way up, which is what you want. Over time, the clutch (brake) fluid gets worn, the pressure plate gets weaker and the system by itself without the spring may not release fully. That causes drag on the TOB which will burn it out very quickly. That small amount of upward pressure from the spring prevents that. These cars already dont have a great TOB design to begin with. Plenty of people have been too cheap to spend 20 bucks on a spring and remove it entirely just to burn out a TOB prematurely.

That information helps! Thanks! I wouldn't simply remove the spring without replacing it with an aftermarket version for that very reason. I think it's strange that Subaru/Toyota hasn't replaced their not so great spring with a better designed one that would make shifting smoother and, perhaps, easier as well.

I would say that while you can’t really “feel” much in the clutch (it never has that “chewy” feeling when it engages), once you know where the friction zone is the 2nd gen twins are really easy to drive. If you’re having trouble, I would suggest doing the really slow deliberate “get rolling with only the clutch” drill to really get the friction zone down in your muscle memory.

clutch in these cars overall in a C+\B- maybe when it’s broken in. Shifter itself is a B+. Pretty damn good but not the absolute tippy top.
