OMGHi2U Shifter upgrades simplified



A: Shift Linkage Bushings
B: Short Throw Shifter
C: Pivot Bushings
D: Front Shifter Stay Bushing
E: Rear Shifter Stay Bushing

These comprise 100% of the shifter upgrades on the market. The reason for this post is to raise shifter upgrade awareness. While short throw shifters are damned popular, one cannot and should not discount the effect of bushing replacements on the overall shifter feel. Plus with their ease of installation and inexpensive costs, there really is no downside to these important modifications.

You can find all the manufacturers for these components on my Suspension & Driveline FAQ, but for those of you that like one stop shopping, you can get all these components from www.turninconcepts.com as they make their own components as well as retail for Kartboy which makes what they don't. Be sure to triple check your make/model/year as some of these parts are very specific in regards to fitment.

Hmmm i wasn't aware that there were Shift Linkage Bushings available? Who makes them? I was unable to find them at TiC.

Current offerings for the shift linkage bushings is for the following:

04 STi
05 STi
06 STi
05 LGT
06 5MT - all models

We are working on a retrofit kit for pre-06 5MT's.

The problem with the pre-06 linkages is that there is a rivet holding the tranny side clevis to the linkage trunnion. We don't think it's a good idea to ask people to grind off that rivet as not everyone has a grinder sitting around, and the potential to screw it up is high. Instead the new kit will have a new tranny side clevis, a new linkage trunnion, the set of 4 bushings, two new spacer sleeves, and two new bolts (one will have to be a custom step screw so you can continue to use your stock control rod).

Another related question:

Looking at the diagram, does anyone know what are the dimensional differences between Subaru's normal and short throw shifter assemblies? Are the lengths of the bars (linkage and stay) different? Is the pivot point on the lever moved?

04/05 6MT shift linkage bushing purchase link
06 6MT shift linkage bushing purchase link

I don't know which one fits the LGT or 06 WRX though, so you'll have to PM Turn in Concepts. I posted these links as, as a Vendor, it's not kosher for TiC to do so in this forum and it is rather hard to find those link on their site. *hint, hint....TiC*

As to the dimensional differences:

Normal shifter has a wider width at the pivot point
STi/SPT short throw shifter has a narrower width at the pivot point

This is why TiC has two unique pivot bushing sets and it's important to know what you have as to what to order. That's a broad generalization of course and your BEST course of action is to PM them with your year/model and get the right advice the first time.

Is this what would cure the slight side to side slop (in gear) I have in my full Kartboy bushing/shifter combo? Not that it's huge, it's just the only slop left in the system.

The pivot bushings will help quite a bit.

The full set of bushings - front stay, rear stay, linkage bushings, and pivot bushings make for the most slop free setup that we feel can be made with the subaru assembly.

engine, tranny, crossmember, and rear diff mounts, as well as rear diff outrigger bushings, should also "clean" things up a bit

I hope the 04/05 6MT bushings will work for us 02/03 JDM 6 speed users! Hey TIC I could be a beta tester for ya! Just to be sure and all!

And my 6MT shifter is pretty sloppy so this would be a good test car!!!!

That is a good question. I thnk they are ok for an 03, but not for an 02. if they don't let us know, and we'll throw a set of the 06 ones at you to see if they work.

We don't have a lot of v3 STi 5mt's running around here. Would it be possible for you to take some pics/measurements so we can see if one of our currents ones will fit?

Hey Ron - I didn't notice you had this thread stickied until last night. When I saw it I though about something that we've been getting a lot of questions on lately. See if you can add this to your post up top since most folks won't read this far down.

What's all this talk of wide and narrow when it comes to shifters?

Ok, here's the deal - there are two versions of the shifter you're going to run into. When folks say narrow or wide they are talking about the width of the pivot point, and it's matching clevis. One version is narrower than the other. That's it.

Ok, what's a pivot, and what's a clevis?

The pivot is that tube that welded perpendicular to the shift lever at about the mid-way point. There might be a better or more appropriate term for it, but this one is easily understood.

The clevis is the "fork" on the control rod that fits over the pivot.

Ok, I got that. How do I tell which one I have?


Here's the breakdown:
- If you have a 1997-2001 Impreza you will need the narrow version
- If you have a 2002+ Impreza you will need the wide version (except in below)
- If you have a 2002+ Impreza with the FACTORY optional short shifter you will need the narrow version

Ok, I have a 2002+, how do I tell if I have the stock shifter or the short shifter?

You CANNOT make this determination from the shift knob. Especially if you have a used car. Many folks put that knob on because they like it, but never touch the shifter. Do NOT make the mistake of saying "I have the Momo knob so it must be the short shifter." You need to pull up the shifter surround and look at the shift lever itself.

Here's how it breaks down:

Stock shifter: The lever will be grey metal in color. It will have a thick body that is filled with rubber. Sticking out of that rubber will be a threaded rod for the shift knob. This requires the wide versions of stuff.

Factory short shifter: The lever will be gold in color. There will be no thick body. Instead you will have a single wire rod going from the cup all the way up to the threads for the shift knob. The pivot will be welded on. This will require the narrow version of stuff.

Why did Subaru do this?

They had a design and parts that already worked - why reengineer it when the 02+ came out?

Who makes narrow and wide versions?

AFAIK, any legitimate manufacturer who makes a good product, has good support, and is truly into Subarus offers a narrow and wide version. Sometimes you have to special order the narrow version. If you are in doubt or have questions, call, PM or email the vendor or manufacturer.

If someone has a pic of the two lever styles side by side showing the difference in the pivot width can they please share. I don't have any of the factory short shifters sitting around.

I'm pretty sure it's the same as the old STi linkages people were putting on their WRX's, no? I can take some pics to be sure.

yes please. If it's the same thing as the pre-2006 5mt linkage then we're still working on that.

Let's see if these help:

Here's one from the rear:


And here's a closer one:


It looks like theres a bolt on the shifter side and a rivet or something unremovable on the tranny side. The inner length on the fork is about 40mm.

Here's the front (tranny side):


So does that look like the same linkage you're working on or different?

Would it be appropriate to list other modifications which aren't directly shifter related but still affect shifter feel?

I'm refering to driveline mounts and bushings.
