Did anyone change the rear lower control arm after lowering?
 

I want to know if anyone change their rear lower control arm for camber adjustment after lowering their car? Did you also change the rear toe and rear lateral link control arms too?

I don't think anyone made adjustable lateral links for the 5th. It's possible to get it custom made because it's adjustable, I remember someone did that for the 4gen Legacys. If you can get one made in china, I'm sure there will be some interests.

There are actually two companies which make adjustable lateral links for our car. Hardrace Taiwan and Cusco Japan. I have just discovered that Hardrace is sold as Megan racing in US based on their part number.

Check these links:

I'm not sure if I have to change all the control arms. But surely the lower control arm had to be change for camber adjustment. The rear toe for toe in-out adjustment, how about the lateral link? I have heard it is also for toe-in toe-out adjustment?

Most who have lowered like the extra camber. But feel free to be the first to swap out control arms, someone's gotta do it eventually.

From my understanding, these aren't for your car.

The ones that are for your car also fit my car as I believe we have similar rear ends.

These are the options (I chose to go with AP):

AP:

These are all for WRX/STI. Are you sure it will also fit our car? I also liked the AP, but it is a little expensive. How about this?

This is the cheapest:

Based by the pictures I was looking at for the AP, they look like the same layout at least

You can go with GTspecs rear trailing arm.

I don't think this rear trailing arm is adjustable.

It looks like someone is selling a made in China rear toe control arm here, but it is for Forester. It is very cheap, only about US40.

Not sure though if it will fit our car. But it really looks like it will.

I took my car to the alignment shop after coilover installed, they told me all I need was the adjustable lower rear control arm. Here is the link

This website also sells it but for 2008-2010 wrx/sti and not sure if it fits on our legacy. Can anyone confirm it?

Based on the listed item in ebay, it seems the WRX/STI and our car (BM9) shared the same parts.

I also initially think we will only need adjustable lower rear control arm, however the more I think about this the more I worry, to adjust the camber to fix the negative camber, the rear lower control arm will have to be adjusted shorter than the OEM one. Once this is done, definitely the position of rear housing will change and not sure if the OEM rear toe and trailing arm will still fit exactly once this is done. But I definitely think it will lead to toe-out situation at the rear.

When are you planning to get this?

Probably couple more weeks, are you planning on getting both or just lower camber arm?

I am planning to get both next week. I'm anticipating the arrival of my new rims next week too. I want them installed before they arrive.
