I'm adding a RSB to my FWD 93 L Wagon. Will the rear lateral links from an AWD Impreza bolt up? (The ones that the endlink bolts to.)

Thanks

Thanks - I was just wondering why Subarupartsforyou.com has two different P/N's. One for FWD and one for AWD. But as long as they will fit...

I'm going to have a shop swap out the lateral links, mainly because I don't have the right tools to do it myself.

Do you have the P/N's for the nuts and bolts I'll need? Where's the best place to get them?

I just put Whiteline lateral links on my car, and decided to buy the necessary bolts ahead of time, since they do have a reputation for snapping. On the plus side, this reputation means that just about any Subaru dealer will have the part in stock, and will know its part number by heart.

I was fortunate; mine came out with only a little persuasion. My friend wasn't so lucky.

I paid $34 for each of the outer lateral link bolts from a dealership (bolts: 20540AA000) (nuts: 20550AA010) (washers: 900335056)
Looks like this site has them for less

I have most of the stock parts that you will need to upgrade to a RS rear sway bar, PM me if interested

Thanks for the link, coger.
Am I going to need the inner bolts too?

I think I have already found all of the parts I need... correct me if I'm wrong:
Lateral links from evil-sti.
Rear sway bar from Carisma
Endlinks from subaruwrxparts.com
04 WRX mounts from subaruwrxparts.com
And now, bolts and nuts from subarupartsforyou.com

The front inner bolt has a dust cap on the thread end so it should be in good shape.
The rear inner bolt provides camber adjustment; if you have adjustable lateral links, you can buy the whiteline bolts that eliminate the camber adjustment.

You will need 4 bolts to fasten the rsb mounts to the frame.
Also four bolts and nuts to fasten the endlinks, I dont think they are usually included with new endlinks.

So the inner bolts don't usually break during removal?

I work at a hardware store, so I shouldn't have any problem finding some bolts to fit.

Next question... My car is FWD, but I'm using the rear lateral links from an AWD. Which bolts do I order?

Bolt for lateral link outer 2WD... 20540AA010
Bolt for lateral link outer AWD... 20540AA000

Anyone know what the difference is??? Which ones do I need?

Those bolts provide toe adjustment. If you have adjustable lateral links, camber and toe are changed by adjusting the length of the arms themselves, so adjusting the inboard bolt for toe is pretty redundant.

If you have fixed length lateral links, you need to keep the toe adjusting bolts, and would have to get either camber bolts or camber plates if you wanted to adjust the camber. Or slot the bolt holes on the struts etc etc.

I was under the impression this couldn't be done because of how the lateral links bolt to the rear cross-member. You would need an AWD cross-member, in order to bolt up the lateral links properly, and as a result you would need an AWD fuel tank, etc.

No, I already have 2 of them. I'm just saying that your DIY is missing the major part of needing a awd rear crossmember or a new long bolt that will work with the awd latteral links. I already tried putting on awd latteral links on a fwd car and its not going to work without either a new skinner long bolt or an awd rear diff xmember.

Summary, your DIY is uncomplete and only works for a awd impreza.

Well either that or find some funky aftermarket bolts....

I converted my car from FWD to AWD and the rear cross memeber on the FWD is a ton smaller. you wouldn't be able to bolt up an AWD hub on a FWD rear crossmemeber due to the length.

the rear of the impreza that bolts up the crossmemeber theres 6 or 8 total bolt holes and you only use 4 for the crossmemeber the center one is the locking.

Thanks for the heads up, dumbuglydragon. I actually rememebr reading that thread a while ago, but I totally forgot about it.

So, it would still be possible to use the two rear AWD lateral links and two front FWD lateral links if I find the right bolts, right? Does anyone know what size bolts I would need?

I don't want to get into swapping gas tanks and x-members, I just want a rear sway bar!

you're right. but, you dont need a rear cross member. what i found was the inner lateral link bolts are to big for the awd lat. links. so i tried one of the outer later link bolts and it worked like a charm. so, you need to pick up 2 outer lateral link bolts aswell as the lat. links.

bolt size is 17mm, you can re-use you rear fwd lat. links, the ones w/o the swaybar bracket. what's easiest is going to your local junkyard and picking you 2 extra bolts that connect the lateral links to the knuckle

What do you mean, I can re-use my rear lateral links? Don't I need AWD lateral links so that they have a swaybar bracket?

So, if I re-use the front lateral links, and use AWD rear lateral links that have a swaybar bracket, then I can use an outer lateral link bolt for the inner bolt?

you can pop the rear AWD lateral links, you'll have to swap inner bushings as teh ID's are much bigger on teh FWD's
So I could just replace the AWD inner bushings with FWD bushings and everything will bolt up to the x-member with the FWD inner bolt?
