2006 STI under car pictures

mx270a · 09-24-2005, 09:12 PM

So I had my STI up in the air today installing the TIC short thow kit, thought I'd take some pictures that aren't so common. Feel free to use any of these for documentation to point out a certain part or something if you have an issue and just need a quick visual for someone else on the forum.

More pics....

Nice lift -- your house?

Thanks for posting. I love the clean lines of the new front end. Can't really detect any major differences underneath from my '05. Not much new with the suspension bits, right?

***TRM*** · 09-25-2005, 04:42 AM

it appears they changed the power steering assembly type or manufacturer. '06 is black. my '04 is green.

Thanks, it's our farm shop. Note the tractor in the foreground of one of the last pictures.

I have no idea if any of the suspension got changed. I'd bet the rear strut issue that was on the early 04s was fixed long ago. As for anything else, ????

Are you talking the steering rack, or the power steering pump? I'm pretty sure the pump is still above the block, so it wouldn't be visable in those pics. I can get a closer pic of the steering rack if that would help at all.

This might be the the same for the 05s since the rack was revised that year.

Great pics mx. Thanks.

The brace at the rear of the front splash gaurd (where it connects) is different.

Singletrack · 09-26-2005, 06:35 AM

Are those points cool to use for lifting the car? i.e. the back of the subframe and the bushings for the rear diff?

I need someone to number and name every part of the car! It would help immencely for mechanical retards like myself! Any one that is looking for a challenge, please give it a go!

Is there any data about whether the diffuser actually does anything, or is purely cosmetic?

Wazazell · 09-26-2005, 12:02 PM

I doubt anybody has any real 'data', but it looks like Subaru included the exact same one on the 2006 rally car. So, one might assume that it really does provide some advantage...?

I'm no aerodynamic expert, and I like how it looks, but I've always assumed that it's either too small, or too flimsy to actually provide any significant downforce. Most diffuser's i've seen on real race cars have:
1. much steeper angles
2. much longer and taller fins
3. span the width of the car
4. heavier bracing to apply the force to the chassis
5. are lower to the ground

As high as the stock STi sits, I can't imagine the diffuser having much effect on the airflow under the car.

**gforced** · 09-26-2005, 01:01 PM

Well, then they changed it on the '05 because mine is different. Man, now I have one more reason to upgrade.

erix · 09-26-2005, 01:41 PM

if you had the SPT short throw, why did you switch it out for the Kartboy?

I know nothing about the subject either, but if the air coming across the drivetrain is not clean (which it shouldn't be as the drivetrain isn't smooth and flat), then the rear diffuser might simply improve that a little and keep the air from grabbing the inside lip of the bumper and producing more drag and possibly lift on the rear of the car.

It sounds reasonable when you are like me and know nothing about aerodynamics anyway.
