Re: Sabrewings' 2009 Dark Grey Metallic STI - "Alli"

Big? Not necessarily. Noticeable, especially the first time you drive it afterwards. It's easy to get used to it, but every time you are lightly making corrections within the old "dead zone" you'll take notice.

I had some trouble getting the alignment back perfectly. I had the shaft aligned properly, but the rack was slightly out of position before the bolts were tightened. If you need help correcting this, let me know. I figured it out with the an extra pair of hands from the wife in the driver's seat.

What were you putting down before the protune? I like the thought of 300+ WHP!!

Re: Sabrewings' 2009 Dark Grey Metallic STI - "Alli"

Spent some quality time with the STI today. Installed the Group N trans mount, TiC tranny crossmember bushings (what a great product), and finished installing my holy shifter kit from TiC (still had to do the pivot and trunnion bushings).

First, I took these pics to help out those having issues on where and how to properly use jacks and jackstands with the GR body. Figure I'll toss them here too in order to show off my tools some too. :lol:

First up, interior is disassembled for shifter removal. Ready to lift it up:



Jack and jack stand placement for the front. Note the awesome lift of the jack. And not even fully extended yet:



My full set up for working under the car with all four tires in the air. Plenty of redundancy in case something fails. There is another gray jack I use that isn't pictured, but I put it opposite the orange one:



My jack stands properly interface with the pinch welds and OEM jack points to prevent damage:



My target for the first phase. The tranny crossmember support. Note the gray sandwich bushing that will be replaced. They're incredibly soft:



Not much to see here, but the new Group N trans mount is on the left. Stocker on the right. The stocker you can flex it with your bare hands, but the Group N is incredibly stiff for rubber. Very impressed:



When I was first installing my Holy Shift kit, I was unable to hammer out the roll pin. This time I decided to try the alternative method of unbolting and lowering the tranny and pushing it to the passenger side to get clearance and remove the bolt. Worked like a charm (and, come to find out, is the factory service manual's suggested method):



OMGeez! There's a hole in the floor! :lol:



Pivot busings (blue ones) were ready to come out. So worn they practically fell out. This mod can be done with the shifter in the car, but why when I'm removing it anyway?



Pivot bolted back up:



First trunnion bushing fell out, just like pivot bushing:



Oh, and what do you know, so did the second trunnion bushing:



After this, reinstall of the shifter went smoothly. I regreased all bushings (including the poly Kartboy front and rear stay bushings). Now, we're looking at the support plate removed from the car. Let's get started. Note the cherry blossom red TiC bushings ready and waiting:



This picture shows the thickness difference of the rear lower bushing to the rest. All four are NOT the same size on the 08+ STI/WRX. This is why I didn't get the Kartboy kit as TiC includes a spacer for keeping this thickness in this spot. Also, these bushings are extremely soft. Could use them in a bag as a pillow:



All bolted back up, not finally torqued though. Waiting to get it back in the car for that. It's not stated in guides, but I greased all surfaces of these bushings as well. They're not metal, so some movement is going to take place. My rear shifter stay had started to squeak on decel at slow speeds a few months ago and I didn't want to deal with that from any of these (greased the hell out of the rear stay to prevent it next time, too):



My thoughts? Totally worth it. Every last bit. This all took me about 3 hours, and I was taking my time with it. Fun day. Shifts are much more crisp, and shifter action is precise with no free play in it at all. Some report shifting gets more stiff, but I would assume they overtightened something. I followed all suggested torque specs and it requires the same effort it did before.

I did miss the gate going to 3rd the first time I was driving aggressively. I was used to the slop of the shifter and rolling of the tranny, so now that the car lacks that the gate isn't quite where it was before. Much more consistent though now in all situations. Much less bounciness in low gears on compression braking, and throttle response has greatly improved. Looking forward to my next round of mounts and bushings!!

Re: Sabrewings' 2009 Dark Grey Metallic STI - "Alli" (updated 2/12/2011)

More work done yesterday. Installed the Whiteline rear diff inserts, the Whiteline rear subframe inserts, and removed the flap on the fender vents. Pictures below. I love what the bushings did for the car's handling and response. Near total transformation. It was agile before, but now it's razor sharp. Great transitions.

Removing vent:


All done:


Finally got the diff support out (one nut was hard because my exhaust prevented using the impact):


Head on shot showing bushing with voids:


All done:


Where the other rear diff inserts go (didn't have to remove sway or exhaust to get to these, just used extensions):


All done:


Where the rear subframe inserts go:


Big *** bolts that hold it up:


Ready to put in the inserts:


Washers I flatted the tabs on per Whiteline's instructions. These are reused on top of the inserts:


Getting close to done:


The top insert here is finally seated by jack up the subframe and the bolt tightening:


All bolted back up:


A few general under car shots. Love the look of all the bushings:

So how does the car feel with the rear inserts now? Is it a pretty noticeable difference? What about nvh?

The handling difference is very strong. I'm amazed at how much for such a little mod. NVH is about the same. I only notice a slight growl from the rear of the car as I get higher in the RPMs. Almost like the tone of my exhaust changed. Nothing huge, just noticeable.

Thanks. I really like your journal so far. You put a lot of detail in and you've done the things that I think should be done to the car that not as many people do :) I really want to get the GR.

Thanks a lot. :)

I'm more into function over form, so that leads my mod path. I also like to take a lot of pictures of the mod process since installing the mods is half the fun to me.

So to get the fender vents off, you just pull from top to bottom?

And it looks like you didn't take them off all the way. Was that because you didn't want to take the side skirt off??

Yep, pull from top to bottom.

And you're correct. I didn't feel like popping out the side skirts (though it is very easy). Just leaning the vent out gives you ample room to remove the flap. Took about 15 seconds per side.

Turn the car to on and turn on the AC (but you don't have to start it). That will kick on the fans. Put your hands next to the vents and you'll feel air moving. Good enough for me. ;)

Do you still have a bit of side to side play in your shifter when in higher gears? On mine I notice my shifter gets a bit looser each gear i go up. I was suprised but still love the new feel.

There is a very very small amount of side to side play. I investigated and it is within the transmission itself, so not much that can be done about it. I only noticed it because I was examining my install. It's so small I probably wouldn't have normally noticed.

Well shoot! if you can feel air (very little but its there!) without the car moving and the ac on, i wonder how well it works while going 65mph

My thoughts exactly. High pressure in the engine bay with low pressure behind the vent means it probably moves a decent amount. hillhucker's method of cutting new holes increases it, I'm sure. But the flap is a free and reversible mod.

def not going to cut holes lol, free mod ftw.

I got a few questions about your installs. I'm going to PM you.
