Stock vs. hard plastic vs. solid aluminum are definitely different hardnesses but I really don't think they'll make that much difference in those bushings. Even the stock ones have very little give/play. It is nothing like the front/rear shifter bushings. I'll be doing them anyways, but I really doubt they'll have much of an impact. Like maybe short shift is 70%, shifter bushings are 25%, and the other bushings are 5%. I guess we'll see.
The rear bushing can be done with the exhaust and driveshaft in place. I would remove the tranny "H" brace to have a little more room. Getting the bolts in is a bit tough. You have to keep in mind the that the bolts will NOT be going in straight/perpendicular to the bottom of the bushing. They go in slightly angled. I mentioned this to Kartboy, and they just said deal with it. Lol. Works fine once you get it started, but it's very easy to strip out the threads in the car and then you're hosed.

Yeah, it's kind of a mediocre design, IMO. But I doubt it will change. People have been dealing with it for years, and doing it right would cost more so people would still probably just buy the current ones.
Depending how bad you mess them up you can probably just run a tap through the threads and clean them up. Worst case you'll have to retap a larger size. Not the end of the world, but still a pain. |

I also agree that those two rear shifter stay bolts are a pain, after a couple hours of swearing at my car, they went in smoothly as soon as I got the angle right and the threads engaged.

Kartboy cited the fact that everyone has copied that design (which they have), so it must be good. Lol. I agree that it's cheap and it gets the job done once it's installed. I definitely think there's room for improvement on the install side of the design. A two piece design with a polymer bonded to a metal base (similar to the stock design, but a harder compound) would probably be best, but it would probably double the cost.

It's partly tolerances but mostly because the mounting surface isn't actually flat so it's designed to have some bend/stretch. If it were designed properly the tolerances would be much less of an issue.

This is really good info, I will be trying to put those bolts in by hand until I can feel that they are starting properly. I think I will also attempt that bushing as soon as I gain access to it to try and keep from getting impatient and cross threading it. I appreciate the info

Glad to see I'm not the lone weenie for struggling with those bolts. Put line in a couple of days ago. The holes line up exactly top the stock ones, so I don't see it being an issue with the bushing itself. Beautiful car by the way xluben. Been creeping around on here for a while, and have learned a lot.

Yes, the holes are basically in the right spots, they're just not quite the right angle. It's very close though. Once you get them in it's fine, it's just making sure you get them started properly. Here are some photos I took where you can see the very slight difference:

Yeah makes sense. Your pictures and measurements also made me stick to the OEM "sti" short shifter which feels fine now with just the bushings. I'm so used to Honda trannies and the slop in the wrx shifter was driving me nuts. Problem solved though. Thank you.

Those pictures give me a better idea of what I'm dealing with, looks like you have to get the bushing to flex enough to make that angle of the stock bracket. I should be installing the whole kit this Saturday, crossing my fingers for it to go as smooth as possible.

It's really quite easy. Just take your time and don't damage anything. Should only take 15-20 minutes.

Have you tuned your car with current mods on 93 octane? If so what were the numbers?

I'm sure this is in here somewhere, but I couldn't find it. Do you have an easy way to flash back to a pump tune in case you're traveling and can't access e85?

I know it has been posted thousands of time but how hard is it to install those kartboy shifter bushings? I already have the STS and if I didn't have to take that out I probably wouldn't have mind going under the car to install these bushings.

You don't have to remove the shifter to do the front and rear bushings. They are discussed on this page and the last. They're really quite easy. Just make sure not to cross thread the bolt holes for the rear bushing.

Hmm so I don't have to remove the shifter inside the car at all? Not sure why I read I have to remove the whole sts assembly to be able to install these bushings.

For the front and rear bushings (the ones that make the most difference) you do it all from under the car. The tranny brace and a heat shield need to be removed or partially removed, but other than that it's not much work. |
