Installed Civic Type R shift lever in my Si

I just ordered the older CTR assembly and acuity bits for it. I'm not sure i would buy the 2020 assembly yet. From what I've gathered the Acuity short throw adapter and the factory CTR assembly are about as short as you should safely go. Any shorter you run the risk of stretching the factory shift linkage cables. Now the new 2020 CTR assembly might be shorter (2-5% i'm guessing ). Now you are putting 2-5% more stretch on the factory Si shift cables. Is that right?

i guess we wouldnt really know how short it is until it gets released.
I think earlier in this thread (could be another tho) acuity short shift adapter for the SI shifter is shorter than the stock CTR per Acuity.
Great reminder though because i do remember Acuity mentioning that any shorter could stress the cables too far!

Although does the Acuity short shifter setup (the $500 one) come with new cables? cause that shit is short! haha

I plan on doing this install with my brother whenever he has time to help me out later on this week.

We installed the Acuity shifter bushings about two months ago and it made my shifts feel very smooth and no more 2nd gear crunch.

I hope the CTR shifter and acuity parts make a nice little difference as well. Thought about getting the short shifter but eh, not for me.

If all goes well i will be doing the same this things weekend haha. Just hope i get the package by this weekend.

Our full shifters don't include new cables. The reason we are able to achieve the short throws on our shifter with stock cables is that we change the cable orientation to be better suited to the lever-arm length required for short throws. On an OEM shifter, you can't change the angle the cable mounts to the shifter, so it limits the max reduction of throws you can achieve using the stock frame.

Very well put and thoroughly explained as usual,
Thanks Russ!

Those of you who have done this: does the CTR shifter produce the "click" noise in even gears that short-shift adapters cause? I'm presuming that since both shorten shifts by effectively lengthening the bottom of the lever, creating up-and-down movement on the cable, the answer would be yes, but maybe I'm missing something.

Mine does not. The CTR shifter isn't as short as the adapters on the Si shifter, which is probably why.

Thanks. Still happy with the CTR shifter and Acuity bits? I'd be doing the same setup.

Yes, love it! A true joy to shift. Shifts could maybe be a bit shorter, but the gate spacing and stiffer centering spring are awesome. The new CTR shifter is supposed to have slightly shorter throws than the original one.

Nope... I didn't notice any stretching of the cables at all with the 2020 type-r shifter. Here is a post of it installed in another thread where we were discussing the same thing (there's actually still slack in the cables).

Also, here is a video to get an idea of how short everything is now. (This is 2020 type-r shifter with acuity stage 2 upgrades) If you buy the acuity stuff... make sure you buy the correct stage 2 kit to match your shifter. (The type-r stage 2 does not have the short shifter part with it)

I've got about 15K on my type R shifter with Acuity bushing, been super happy with it.

I am yet to install but I guess type R shifter shouldn't do that as it's OEM and not extending the cable farther like the adapters

This is a misunderstanding of the OEM shifter. ALL OEM civic 10th gen shifters have the same plastic base, so the cable attaches in the same manner. The shifters vary by the length of the shift lever from the main pivot to where the cable attaches among other things. The base has the shortest length for this dimension, leading to longest throw, the Si is slightly longer, so shorter throw yet, and the type R longer still, so even shorter throw. The cable angle varies between those 3 shifters due to this fact. That said, the OEM cables can safely handle something like +/-7 or 8 degrees if memory serves correctly, which is actually a ton of range. So mechanically it is no problem. That said, on an OEM shifter where it doesn't grip the cable rigidly like it does on our full shifter, as that cable angle increases, the likelihood of hearing a little noise from the cables during shifts increases. So a type R is more likely to make the even gear "clunk" during shifts than an Si, and a base is least likely to produce the noise.
