the 05 has wider rims than the 04, 8invs7.5in. I don't know that 255 would fit on 04 rims, but they ould if you took his 8in wide 05 ims.

silvrsti: What I have swaped (05 rotors, wheels, hubs and knuckles) will work. The front 05 axles WILL NOT work with an 04 front diff so you will be stuck with the wheel speed problems that I have described above until the new sensor gear are made...

wow, REALLY? lol

might as well swap over the entire suspension.... seems like you'd be able to just unbolt the entire thing and swap it over instead of doing this conversion and messing with the hybrid parts. Might as well swap the entire rear diff and maybe tranny too so you have the '05 axles... get the longer rear links and helical frint diff as well... and the 05 headlamp housings too... lol... might as well swap the seats and centerconsole/dash... ROFL

I can just imagine whoever buys that used 05 trying to upgrade the suspension or wheels, buying parts for a 05, and saying WHAT THE .....

The fitment of the wide tires has nothing to do with the 05 conversion. It is facilitated by his widebody setup in the front and the rolled/clearanced quarterpanels in the rear.

Javid did this swap to increase reliability for track use. If you just want wider wheels/tires, go buy a wider set in 5x100.

Bingo. Of course, wide 5x114.3 wheels are going to be cheaper and much more available than 5x100...

Sounds like a pimp upgrade J, but I can't run STi V7 rims on 114.3 so on that- I wonder if the actual hub from an 02 can be used in the 05 carrier housing?

btw, ever replace "teh elvises"?

What up Killa, my borther got me a fresh pair of shades for my graduation gift.

There is no practical way to run 5x100 wheels on the new front bearing. It comes as a sealed unit (complete hub, bearing, housing, bolts to the knuckle which is not the same knuckle as the 02-04).

Unfortunately I am still out of town. This will be a top priority when I return.

I will update the thread when it gets done if you want to subscribe.

any updates??

Also curious about the knockback correction this has. Right now all 4 corners "klunk" really bad and my peddle pressure is pretty poor. I'm guessing this is knockback. But the weird thing is....it's the worse at a slow roll. Like if I'm in a drive through getting food and i'm slowly creeping up. When I hit the brakes to come to a stop, they clunk the worst. Is this knockback or some other "gremlin" I have to deal with?

I currently have 2 seasons of auto-x on the car.

also do you have a list of part numbers we need from the dealership. My dealership is pretty stupid and in order to get the correct parts, I have to give them part numbers.

Update: I have not driven the car for some time, I have been out of town working in Ohio just north of you ironically. The problem that I thought was in the rack was actually the rear links loosening up and developing about an 1" of toe out in the rear. That combined with slight toe in up front makes for some pretty strange fead back in the steering wheel, especially during turn in or transient. The car was never alighned after the swap, but freind picked it up last week and got the alighnment done. Anyways, I figured I would let everyone know that the suspected rack problem had nothing to do with the swap.

Knock back is more noticeable the more you load the bearing. The load is generally greater at higher steering angles and of course with more grip. In a controlled setting, tap the brake pedal up. If your fluid is fresh you should be able to tap a couple times and start feeling the car jerk with little pedal movement (pads are tight against the rotor). Then give some sharp steering input back and forth (note you don't have to go fast or make the car slide, just quick lanes changes at 30 mph should induce the problem). After the transient, slowly start pressing on the pedal, if you can press the pedal down a good bit before the car starts to slow, then you have some knock back (initial pedal movement is pushing the pads back to the rotor). The pads move off the rotor because bearing flex moves the rotor realtive to the pad and pushes them back into the caliper. In my experiance, once the bearings were starting to flex, I could get them to flex more (initial pedal movement before the car stopped was the largest) by doing 5 mph U turns at full lock. Try that after you try the transient lane changes. Just before the swap I could do a U turn and fully depress the pedal and th car wouldn't stop. At that point the bearings were also starting to whin a little (not a blown bearing whine, just a slight whine) which is a sign that they need replacing.

In any event, my bearings got bad quickly because of all the track time with track pads. The extra heat will cause the bearing to go quicker.

I could notice a fair amount of knockback during my 3rd track day with the car (2nd event with the track pads). There is no official word on how long the 05 bearings will last but many 05s have already done a few track days with no signs of knockback.

Your clunking may just be backing plates that are getting load. I just ignore it. You can grease the pistons up next time you are working on the brakes and that should solve the problem.

Parts numbers: I have my reciepts back in atlanta. If your lazy you could just call Subaru of Gwinnett and talk with Scott Siegel and tell him you want to do the same swap, he will know what you need as far as subaru parts go(front hubs, front knuckles, rear hubs and bearing, and front struts if you don't have coilovers). Then you need to pick some rotors and wheels. Note that aftermarket 05 rotors are still coming out. Some makers have them others quote 'a few more weeks'. I have my eye on some TWR two piece floating rotors.

The custom gears should be available next month.

Javid,

If you get the speed sensor wheels please PM me. I will buy a set just in case I want to do the swap in the future.

Much appreciated,
Justin

PS - great info on this thread!

This is pretty cool info, now something to laugh at. Most of this stuff was on a SVX and its pretty funny to see the same part numbers pop up on a 05 STi. The SVX has the 5x114 bolt pattern and thank you Subaru for putting it on the STi. Now we SVXers have a pick of rims and suspension that werent available before. Im still trying to see if the Brembos will bolt onto my SVX.

Does anyone have the bolt pattern on the knuckles(meaning the distance between the mounting holes for the calipers)

the brembos should bolt up to the svx, the suba 4pots also bolt up, but you need to get custom rotors because of the spacing of the bracket... i think it was somewhere around 14.6" rotors to use the 4pots, but the brembos should bolt right up

ok how and where do you get custom rotors? My other option is just to get the 05 STi knuckles/hubs.

So are you saying I can buy the SVX knuckles and hubs instead of the STI hubs and they will be the same thing?? Because we all know anything that has the letters STI in it, Subaru jacks the price up ~50%
