Angry Bent Lower A arm

I had a little run in with a curb last night and bent my front right lower A arm. Is there an STI replacement or some place online I could Fed-Ex a part here pretty quick? How much would the dealer charge me to fix. I would call but no Subaru dealer is open on Saturday

edit: I must say BTW that the US WRX control arms are crap. Lots of unsprung mass and not strong by any means. I barely touched the curb and BAM bent. My Prizm use to hit curbs all day long but it's all cast iron under there it seems.

Sounds like your SOL.

There isn't a cost effective replacement other than factory stock arms. FHI has a set of GC8 aluminum arms that can be ordered for a huge premium. These alu arms can be used instead of the standard stamped steel ones. However, the dealer is probably gonna be your only bet on a set of steel arms come Monday.


I've might a set of stock wagon arms for sale...

Are the STi Aluminum Control Arms found here gonna work (says for sedan) or can I make them work? I'm looking to upgrade the suspension anyways. Not really worried about cost too much just want my WRX back on it's feet. Also what would an anti-lift kit do for me in addition?

Not gonna work. Well, you could but you'd throw your whole front end off... heh.

The wagon front end is a GC8 front end. GC8 alu arms are about $1k bucks. Like I wrote above, go get a set of steel arms from your dealer, cuz very few ppl will invest in a set of GC8 alu arms, other than the fact that there getting more and more rare.

Hmmm. Thanks for the reply, I really apreciate it. I wonder if the conversion could be done though and what I would have to change. I'd probably end up with a lot of negative camber but that's not such a bad thing.

The anti-lift kit will run you anywhere from $120-$160. In my experience, it's the best bang for the buck suspension mod, along with a sway bar.

And it's not as difficult to install as most people make it out to be... if you have an airtools.

There has been some differing of opinion on aluminum control arms, here, in the past.
Some have said that it is preferable(much cheaper) to bend the steel control arm rather than the body of the car in the event of an accident. It would seem that the aluminum arms don't bend and thus damage the body of the car.
It has also been posted that the aluminum arms weight is almost the same as the steel ones.

I, personally, would much rather bend a control arm and have to replace it than have to(try to) have the frame straightened.

The problem is that the wagon is missing roughly .5 in on each side. Now if one installs sedan arms, where is that extra inch gonna go? Hmmm. Try this one on for size... the wagon doesn't come with fender flairs hence there really isn't any extra room for 02 sedan arms.

Add to this all of the altered mounting points for various bits, not to mention that you'll need a new swaybar, axles, etc...

Now you'll have a car with roughly a 1 in wider front track versus the rear. Talk about understeer!

Sorry, just joking. But seriously though. I just picked up a set of used GC8 aluminum arms for $350. Had the ball joints and bushings and swaybar links. A little cleaning up, and the aluminum shines like new (I love alluminum). I just sold both my stock steel arms for $100 for the pair. Sorry you're late.

I'm in the process of installing the new arms with the motorsport version of the Whiteline ALK. Airtools definetely help with any work on big tight bolts. Also helps if you have something to pry the control arm down with so you can slip the ALK on. It's a tight fit.

Because thats a Toyota in GM clothing.

You had me wondering because I had a little curb shot the other night. I think it felt worse than it was cuz that tire was a little low on air. No marks on the wheels though so I am not worried about it. It goes straight still anyway.

They are designed to bend so that more expensive, harder to replace things like your front crossmember do not. There is a fail point built into the control arm, and it was done for a reason . Saying they are weak and built like crap speaks volumes to me that you have absolutely no idea of the force generated on them in an impact with a curb at even 10mph.

I see your point about the control arm. I read something in SCC about DMS coil-overs having something similar on them. It just prevents more $$ damage from occurring.

Nice title under your name North Urs.

The GC8 aluminum control arms fit the wagon perfectly. Subaru never offered aluminum control for the WRX wagon, specifically.

My stock control arms have been through rally-x, curb hopping, flying over speed bumps, you name it. They're fine. Nothing crappy about 'em, IMHO. Of course, I've never gone sideways into a curb, either.

Got the part in today, install tomorrow. Trust me, I know all about the forces generated on suspension parts. I really wasn't going that fast and just thought if every time I rub a curb this is going to happen, then this is going to suck.
