Thumbs up Recommended F/I RS Mod: Group N Pitch Stop

I'm not sure you guys know, but I broke my Shifter Stay Rod a week an a half ago. The rod is the bar that the shifter pivots on, it goes forward to the bushings (where people put kartboy, or cusco stay bushings), and eventually connects to the tranny. I was driving normally, did the 2-3 shift, and the shifter went to the floor. Here's what the bar looks like. This is the broken bar from my car. It broke where it connects to the large ring on the left, the small hole is where the shifter sits.


Cheap part ($60), expensive labor ($270 total) considering they have to remove the ENTIRE shifter assembly (Subaru sells the entire assemble with the STi kit considering the correct way to change the shifter is to remove the whole assembly, then take it apart). I have a feeling it broke due to the motor rocking back and forth on it's engine mounts. The increase in power from the turbo made the rocking worse, as did the added weight of the IC sitting on top of the engine.

I had a set of STI motor mounts, but I haven't gotten around to installing them. After my problems with the shifter assembly, I decided it's time to do something about the engine dance. So, I called up Pam at ISR, and ordered the Tranny mount, and Group N Pitch Stop bushing. They arrived tuesday, and I decided to see if I could install the pitch stop without any help, so I pulled off the Intercooler, and got cranking (I'm installing the engine and trans mounts sat with the help of a friend).

Required tools, 14mm socket, small 3/8th extension, and 14mm wrench. Once the bolts were off, with a little pushing and tugging, I got the stock part off. I compared it to the new one, and what a difference!! Here's the stocker:


And here's the new one:


After trying to figure out why Subaru would put such a crappy part in the car, I installed the new bushing. Surprisingly, it was pretty easy to install (it's not marked which side is up, so I installed it with the Subaru wording readable from the side). I torqued down all the bolts, and took it for a spin.

First off, the normal clunk I'd sometimes get from the IC hitting the firewall is gone. When driving, the car seems to accelerate and brake better, it feels more solid, since it's not waiting for the engine to settle anymore. Cornering was the same as before, felt a little better. Shifter feel is better as well. As far as NVH, there wasn't any noticable changes. Idle feels the same, no extra vibrations, nothing. The car idles like it still has the stock bushing. After driving, I began to wonder again why Subaru went with the crappy stock bushing.

Anyway, total install time, 15 minutes, and the part costs 49.95 from ISR Performance. Check it out.

Just wait till you get the engine and tranny mounts in. Your motor will move less than an inch in any direction.
Although I need to learn how to reshift now that there is much less play in the tranny.
Next I think are the shifter bushings.

Good luck on your install!

Cool! Looks like I'll have to pick one up soon. I've got the motors & trans ones already, so this is just the next step.

I just looked at the STI mount install instructions, and they say the pitch bolts are 12mm. I think they're 14mm, but I may be wrong.

I don't have the part number here, but I think it's on the box.

I purchased the same part and when I took out the one in my car it was the exact same part, looks and number. So for some reason my car already had the upgraded pitch rod. This was an MY98 RS-T. I figured the company messed me over but I was to lazy and never called to check. Now that I see what the stock one looks like just looks like my car was a freak? Oh well looks like it will go in the new car hopefully it's not a freak so I get some use from the part.

Suabru uses 14mm heads on M10 bolts. 12mm heads tend to be on M8's but I've seen some eceptions where 10mm heads are used on M8's, and 12mm heads used on M6's (those might have been from a previous owner).

Its nice though that Subaru rarely ever puts something that isn't 6,8,10,12,14,17,19,or22mm on the car. I have found a few, but most of those are so you can take off fittings with a single wrench set. Oh and I don't know what some of the HUGE bolts are past 22mm, as I just bought a $3 1" socket for the knock sensor.

IMPORTANT: Group N bushings are made in the same molds as the standard bushings, and therefore have the same part numbers printed on them. The difference is in the material they use to make the bushings - the Group N bushings are very significantly tougher.

I actually bought a set of "STi" motor mounts from Troncolli, which were supposedly the hardened ones, and received the exact same pieces that I had on the car because they were ordering by part number.
