It's very weird to see the downpipe and the steering linkage near each other.

Yeah, that picture shows just how small the angles are on that shaft. I'm wondering how much being out of phase will make a difference in feel. The smaller the angles, the less the angular velocity from input to output will differ.

Call it a hunch... but I'm pretty certain the guys at Subaru didn't mess up the shaft phasing when they took the rubber out of their shaft. It's the sort of benefit you get when you are designing the part from scratch.

I did some simulations and calculations in excel using some measurements I took off my car. I'll post up the results tomorrow when i get back to my desk. 90 degrees out doesn't seem as bad as I would have initially thought. In fact, the phasing might not be as critical as I thought due to the joints being at relatively small angles to begin with. The true test will be when I try out this linkage.

I already have another solution to maintain the factory phasing worked out and should have one ready to test next week.

You made your own solid steering linkage from WRX unit? If so, did you clock it correctly or connect it straight across like the posted pictures?

Oh, sorry, I thought you were asking him if he ever got around to replacing it with the STi linkage.

What was your impression?

Was it simple to keep everything straight, as it looks like the STI unit ends are clocked differently?

Yeah, it wasn't hard. One side or the other (can't remember if it's top or bottom) has a key (single spline that's very large) so it clocks it to one half of the system. Then there's only one way to spline it to the other half of the system that keeps it so that the steering wheel and wheels agree. Pretty easy overall.

I'd say it's basically like doing any other bushing upgrade to the car. Better feedback, more precision, more confidence in what the car is going to do. This turns into me being able to place the front end much more precisely where I mean it. It's something you don't really notice until it's fixed, but at high speed/high load, but the stock linkage allows you to get the front end basically where you want it but there's maybe a 6-8" fudge factor side to side depending on exactly how the front end feels like tracking. This reduced that greatly, down to an inch or so. Front in wander on the freeway is also greatly reduced. This is in the context of literally every other (good) mod sold already being on the car

Money well spent. Only drove it a little bit, but I feel much more connected to the front wheels. It goes where I want it to go and not just in the general direction.

I just did this. It is the best steering mod I have done since putting in the six speed. Made the steering feel much more crisp.

Just replaced my stock WRX linkage with one I nabbed on eBay from an '05 STi. A nice incremental upgrade, more feel through the steering wheel and more precise and direct response to inputs.

Of course more feel means a slight bit more vibration, but that's pretty much always the tradeoff. In this case the downside is small compared to the upside.

It's an easy and cheap upgrade that is well worth doing.

A couple of notes from my install:

At least on my WRX wagon the linkage was easily accessible from the bottom without need to loosen or remove anything else.

You must completely remove both clamp bolts to remove the linkage, just loosening isn't sufficient.

You want to maintain the existing relationship between the steering wheel and the rack when replacing the linkage.

The steering wheel end is keyed, so you don't have to mark the location of the shaft & linkage. However you want to avoid having the steering wheel rotate when the linkage is removed, because the roll connector has a limited amount of rotation. Without the linkage the steering wheel can freely rotate. Best advice is to lock down the steering wheel somehow with bungee cords, an improvised clamp, a helper, etc. to avoid damaging or needing to recenter the expensive and delicate roll connector. Recentering isn't the hardest thing in the world, but it is easy enough to avoid.

The rack end isn't keyed so marking the shaft and the linkage and then transfering the linkage mark to the new linkage is the best way. A silver Sharpie works pretty well. Near as I can tell the WRX linkage and the STi linkage have the clamps at the same angles, so transfering the mark from one to the other is straightforward.

The alternative to marking and doing it the easy way is multiple hit & miss attempts to align the rack and the steering wheel. Don't ask me how I know.

I did the rack bushings a couple weeks back and while under there noticed the rubber linkage and was confounded by Subaru's decision to implement such a thing. Before finding this thread I was considering something akin to kpluiten's first solution and was pleased to read here that there is an OTS solution in the Sti unit. However, I'm a little fuzzy about the part #'s listed and their respective applications.

Can someone familiar with these parts post a definitive "for years 20xx to 20xx, use P/N XXXXXXXXXXXXX" or at least "...use linkage from Sti 20xx to 20xx"?

Thanks - I saw #24 but I must have skimmed past Post #32, which confirms the number suggested in #24.

So, for cars from 02-07, the 04-07 Sti linkage works and is P/N 34170FE050.

So for an 07 2.5i it would be the same as the 07 wrx which is the P# above?
