cost.... alot.
from my understanding you not only replace the hub and brakes, but you also need to replace the rear diff and rear axles, becuase the spline count.
I am not 100% sure but I remember reading it somewhere on here.

I've done it. Fronts can use the existing axles though I believe you need to relocate the ABS tone ring. Rears are exactly like AWD stated. I actually switched everything so, it's a bugeye with STI guts.

Full swap, down to the fuel tank. Kept the 03 interior because the 05 interior quality was pretty crappy. Changed all the wiring harnesses too.

I'm checking out 6 gun's kits and unless you have STI knuckles in the back, I don't see how it's supposed to work for WRX's with the R160.

http://www.6gunracing.com/products.asp

So, I don't see a 5x100 hub re-drilled for 5x114 hub on their website. Nor do I see a 5x114 hub re-splined to accept the WRX axle. Considering the size difference between the 5x100 and 5x114 hub and the much larger bearing used in the rear STI knuckle, I don't think such a conversion exists.

I LOVE 6guns products and highly recommend them. Even with my swap, I'm still running the 6gun front knuckles because I already had the WRX style front struts.

I'll be dipped. I would have sworn that it didn't require the r180 and STi uprights.

Editing my post to remove the bad info. Nice catch.


Edit: I've just been lusting at the 6gunracing site for bearings and looking to keep the 5X100mm for my car.

I highly recommend their front 5x100 kit. If you every decide to go 5x114, all you have to do is switch bearings which is 30 minutes per side and no special tools.

Naw, just parked the cars side by side in my shed and started swapping. Did it last winter. It wasn't hard at all, just time consuming. I chopped the old STI carcass up with a sawzall and took it to the dump a truck load at a time.

The only hard part was re-wiring the harness for manual AC. I didn't want auto AC because of the weight and because of the 03 interior.

Had it out at the track last weekend. Only got passed by a couple 'vette's and a viper ( I was on street tires). It ended up being a really great thing to do.

If they could come up with a good alternative for swapping to 5x114 in the rear I'd be all over it. I'm sure many others would too.

Theres really no other alternative in the rear, r160 and r180 part are not interchangable in the rear for the swap.

I think Im one of the few on here with a hub swapped 5mt. To get even better parts doing the swap drop in early 04 sti front axles, they have a much stronger cv. Buying used parts I think I spent 4k not including wheels and other upgrades at the same time.

Not sure what you mean here. The R180/R160 are interchangable but, the axles themselves are the issue. If I was doing this swap and I wanted to maintain 5x100, I'd either get 04 rear knuckles and brakes or I'd get the DSS conversion axles that have R180 joint in the inside and R160 style joint on the outside.

The STI knuckles are a huge upgrade over the WRX knuckles. The bearings are much larger and the hub is stronger and thicker than the WRX part. I believe you can actually take any year STI knuckles and simply install the 04 bearing and hub into it. That's essentially what 6guns kit does in the rear.

It's tempting. I have a "no-R comp for HPDE" policy but, VIR really tempts me. So much of what a car can do is the driver though. It's possible the driver's of these 'vette's weren't very good and that a good driver would be much faster. If you look at the tire sizes a 'vette runs, the weight, the power and the track, it shouldn't really be possible for me to outrun them if they're good. Not without me stepping up to 500 hp and having a motor that needs a yearly rebuild.

Yes, the rearend is, but the only way your going to get 5x114.3 in the rear is with r180 hubs and axles. Thats why its very easy for 04sti to swap, they just get the hub in the rear.
