Default Ok, V7+ equipped GCs, explain me something

track width
did you use the GDA axles front and rear?

I am trying to come to a logical conclusion

if you use GDA axles, hubs etc. (basically the whole lower part of the GDA transfered to GC, right?) you by doing this widen the track of the car
so now, in order not to rub you would have to stay on 53 offset since 48 would be sticking out too much because of the longer axles

is this right?
can you also do the following, use GDA rear end (widen the rear track) but keep stock, or V4-6RA axles and put them into GDA front retaining the diff, brembos (let's assume we are dealing with USDM STI swap here)

by my estimations, which are far from being precise, that would give you the same track as 22b has. It's a guess I've been reasearching this for the longest time, and will do some measurments on 22b when I go to Moscow in summer

Help me solve this dilema

dude, why didnt u just call mean ask LOL

axles and everything stay teh same, if u do a motor and tranny swap, keep the axles, all u are doing is swapping the tranny and motor. nothing else really changes..(except for the motor where the crossmember changes..)

if u want to have a wide track like a 22b, use 02+ GD sedan control arms in the front for the rear maybe you can use the 05 sti lateral link setup...

I thought RS axles don't fit in STI diffs

yo, when am I getting that hood btw?


acording to my calculations, to achive 22b track, you keep the front end (like Ver IV RA) AND use GD rear end

22b arse is wider as you know, and the additional track is achieved by rims
as I said I will be able to confirm that after I measure my friend's car in summer

If you get a STi Rear subframe assembly just swap out the lateral links with the RS ones and you should be all set.

Interesting thought, and I really hope you're not right! I just did the whole swap (mechical part of the swap anyway, wiring is not done.) - I used 04 sti everything. Front hubs/control arms/axles & entire rear end. And I just ordered Torques with a +48 offset. I really hope I dont have major rubbing issues due to the offset of the rims. I hope it all works. Ahh you've got me very worried now.

How wide are the rims? 8"s will rub. I'd keep the GC rear track too, btw.

Reuse the GC front arms, and GC rear lateral links.

^This is 100% neccessary? Siigh. I gave the front arms to the girl who purchased my setup. I was in a rush and didn't feel like taking them off the k-member so I just gave them to her.

The person who sold me this whole setup definatly misinformed me then. He said it should all bolt right in, and i'd be good to go. He said "I am giving you everything you need for the swap, its pretty much a direct bolt in" - Which is very untrue. Ive had to modify several things to get them to work on my car so far. Are there aluminum front arms I can buy for gc's if this is totally neccessary? Man this is REALLY annoying as I just got everything bolted in. Sigh....

Rear track is what I stated, reuse the GC lateral links. Honestly, I would look into upgrading them instead of using stock. I'd suggest the STi 6pc lateral link set for the GC8 or at the very least upgrade the front lateral link to an aluminum one from the 05+ WRX wagon or Saab 9-2X Aero. But if money is an issue, keep the stock ones they will just fine.

For the front, Yes the STi aluminum arm WILL bolt up, however the front track will be wider. If you're using the GD crossmember, they will fit into the crossmember without an issue. If you go to GC aluminum a-arms (they are available, I'd check eBay from time to tome), you will have to shim either side of the control arm where it attaches to the crossmember with washers.

Also, 17x8 +48 wheels(with 225/45/17s) might constitue an issue with the struts/springs, if you are running them

Ok,

I'm going to use Hyper's pictures, and I hope he doesn't mind...

I am gradually swapping my track to what came with the driveline (V9 Spec C)

so for anyone curious what a GC with 05 STI track (widest rear track, wider than previous MY) looks like - here it is!

This is 05 STI aluminium lateral links, which are 42cms center of bolt to center of bolt, ~2cms longer each side than GC, ~1cm longer than normal GD
Wheels are V7 17x7.5 +53
Tires are Potenza RE070 225/45/17 (however in fact, the tire is 235)













no rear camber yet, no rear sway

Going to the GC front control arms will give up the additional castor that the GD STi arms give you.

Seems to me the better solution is more camber, rolled fenders or more ride height.

I'm not giving up any castor if I can avoid it. camber bolts are on the way and I'm trying to source some oilcovers.

What would be awesome is if someone had pillowball adjustable top mounts for the rear of a GC.

that might be the best solution, then. I wonder what they cost.

EDIT: about $200 from japanparts.com

on my setup I was able to gain -0.6 rear camber with hotbits rally coils (they are really beefy), perhaps when I get "normal width" 225 rubber I might be able to squeeze out more

now I am looking for a cheap solution to flare my fenders

Default How's your "Widening GC Project" going Hyper?

I have a MY98 Impreza Sedan L and am thinking of adding MY05 STi front end (aluminum control arms, axles, brakes, hubs, swaybar & endlinks), rear (lateral links, axles, swaybar, links, and 2-pot brakes), and 17x8 wheels and tires.

Hyper: How's your "Widening the GC - 22B Project" going? Did you get to measure the 22B?

Am I understanding you correctly that the 22B has a wider track in the rear than it does in the front?

I am doing a WRX swap into my 95 Impreza, would it be better to keep the rear lateral links from the WRX so the rear is a bit wider than the front, or should i put my 95 rear lateral links (or aftermarket GC links) on the new subframe putting my rear stance back to stock?
