Default STI strut install!!!

I just wanted to let all you RS'ers know. that i installed a set of 05 sti struts and springs and OMG!!! my car is faster(put the power down tot he wheel better) corners like mad!!! and stops shorter!!!

I lucked out and got a set of struts and springs for $100. don';t ask me how. but they have been by far the best investment!!!

Were they direct bolt on or did you have to modify anything?

OMG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!

No, your car is not faster. You have no less drivetrain loss than you did before, you just don't feel the rear end squat like it used to because of the stiffer suspension. I'm sure your car is quicker in the turns, but it's not any faster.

What was the point of this post? Is this a special application? Are you bragging? I don't get it.

Why, or why not? Strut top differences? Knuckle mounting differences? If you are going to say "BS" you should at least explain why. I have no more reason to believe your response than I do the OP. Not saying you're wrong, but you should back up a statement like that.

05 STI = not possible

04 STI = will directly bolt on.

Simply has to do with the wheel hub design between the 5x100 bolt pattern one and the 5x114 bolt pattern one. They are of different thicknesses and bolt spacing.


Congrats on the swap. It should be a considerable bump up from the stock RS setup, but in spring rate and dampening. Everything should feel a good bit firmer and more responsive, less roll, etc. It's a nice sport setup, most anything around the STI rate is be it direct take-offs or any aftermarket combination.

If you haven't upgraded the rear sway bar, grab an OEM 20mm WRX one from SubaruGenuineParts or similar, $85 new. That'll help neutral out the handling and knock out even a bit more of the roll. The car should feel pretty spiffy after that. I'm not really sure what comes stock on the 04 Impreza. If I were to guess a tiny twig of a 13mm bar that's better used as a placeholder then a real suspension device.

ok, let me clarify, I was told they were off and 05 STI, they mounted perfectly(which must mean they are 04's)

and if the rear and is squating less qouldn't that mean i am putting more power to the ground. BTW more horsepower is not the only way to make your caraster. it's also has to do with the ability to put it to the ground(DER!!!)i.e. clutch, lightweight wheels, mounts and bushings,and so on.

All I know is that they are the **** compared to RS stockers.

I do have a 20mm WRX Sway bar which also helps alot in the turns.

Were you breaking traction before you installed this suspension? If not, the same amount of torque is being applied to the ground through your tires, driveaxles, rear diff, driveshaft, center diff, and transmission. I suppose that one could argue that it takes SOME amount of energy to make the rear end squat, but I'd argue that the car is still trying to do that, but the new springs are just resisting that force. I don't think it's converting the inertia into increased drivetrain power. I'm sure the car feels much more responsive as the suspension reacts faster, meaning you feel the effects of acceleration sooner.

If you were, then if you increase traction through means of suspension modification then yes, you would end up putting "more power to the ground".

I absolutely know that increasing power is not the only way to go faster (think: sportbike with 150HP and GVW of 450 lbs).

LOL, yes i was able to break traction(with my Blizzacks) lol, I don't know if i can with my pilot sports.

All i know is that the car IS faster. not that i am making more hourse power. i'm just using it more effectively.

Ahh, the good old butt dyno and how it can fool our minds. It's because you're squatting/diving less which makes braking and acceleration seem faster because you reach full squat/dive sooner.

Easy way to tell is '04 STi struts = pink/red, '05-'07 STi struts = black. The springs are black on both.

The '05-'07 STi struts will bolt onto an '04 RS up front, but not in the rear. '04 STi struts are a complete bolt on.

ok, mine are pink. thanks for clearing that up!

no is it takes longer to reach the bottom of the squat doesn't that mean your wasting more HP??? if you shorten the amount of squat then you wil achieve forward movement faster...right???

other way around. front struts don't fit.

1. why is this in n/a powertrain
2. this is very well documented in the suspension section.

Does it matter what year? I know some guys with wrx's who've upgraded and could get a cheap one

yes it does - only the 02 and some (early) 03 WRX sedans got the 20mm rear bar

but I agree this really does not belong in the NA Powertrain forum
