When I installed mine, I wasn't thinking, and two of them are off center which is going to drive me nuts already. Ugh, looks like im gonna rip it all apart again this winter.

I just snapped one of mine in the exact same spot on the link, just on the drivers side. I was trying to figure out why the car was pulling so weird. It almost seemed like torque steer when I got on it, but then it kicked back the other way when I let up. I got out to start looking things over and noticed an inch or so of tow-in on the LR. Looked underneath and it looked just like Vew's picture only opposite side.

I gotta go the quick and easy route for now and just replace the broken one. $62 shop cost from Subaru, will have it tomorrow. I'm not looking forward to getting the big ass long bolt that goes through the links and knuckle out. Good thing I work at a shop with some persuasive tools !

Damn, could have mine for free! That's assuming that's not the side I had to remove with a torch (destroyed bushings). Oh, and check your sway bar condition. When I snapped mine, it bent the crap out of my aftermarket RSB.

Saw your post Kirt, and feel your pain. But on the bright side you get to build a stout short block

Gotta get mine fixed fast, as I'm down to one car currently and scheduled to thrash it at High Plains Raceway on Friday !
It looks like my 25mm Cobb hollow bar survived OK

Lucky you.. freaking rust. Too much salt on the roads in the winter.

Do you think if you upgraded the lateral links when you did the sway bars you would avoid the snapping problem or are the aftermarket links not that much stronger?

Perrin endlink problem

the lateral link failure is actually caused by the Perrin endlinks. The spherical ball joints allow the endlink to flop over to one side, causing undue stress on the lateral link. Perrin now makes poly bushings to go on either side of the lower spherical ball joint keeping it in alignment and not allowing it to flop over. Even though Perrin's poor design causes this problem, they charge for the bushings that fix the problem. Most likely to avoid being held responsible for the problem. Everyone that I know that uses the stock plastic/rubber endlinks has NOT had this problem. Sorry for replying to an old thread, but it was a matter of safety. I have had no issues with my lateral links since installing the bushings. Because I had to pay for the bushings that should have been free I no longer do business with Perrin.

Holy Old Post!

Glad to hear you got everything sorted out 3 years ago Vew! hahahah

This is actually pretty common with large rear swaybars and sticky tires. I've seen it happen with stock and aftermarket end links, so it's not a fault of the end link design. In reality the Non-STi lat links just aren't designed to withstand as much stress in that concentrated area. The larger swaybar puts additional stress on the junction between the endlink bracket and the control arm and the arm shears at the weld.

Best bet is to replace the rearmost lat links with a stronger design like the Whiteline or DME arms. You can buy them in full sets of 4 or just the rear pairs if you are on a budget.

Check our site for more info:

Whiteline: Whiteline Suspension Adjustable Control Arms 13 12 11 Subaru Impreza

DME: DME Suspension Rear Lateral Link Arms 07 06 05 04 03 Subaru Impreza

Hope this helps someone else out the next time this post gets bumped in 3 years! lol

We all live and learn. It's not the first time that Perrin did something shady. But, I don't want to bash a Seller of merchandise too much.

Again, just in the interest of sharing all information: I have seen this happen with stock end links also.

We don't sell perrin products but in my experience this failure is not solely the fault of their end link design.

I like people bringing up old posts. Just means people are using the search function!

Perrin on top of other personal bad experiences has left a sour taste in my mouth even excluding this situation. However, I do not blame them for this failure. I think it's common enough for it to happen; most notably, those of us with upgraded RSBs.

My vehicle had to be towed out of a ditch several months back using the RSB so that is likely what added to the point of failure. It's just another risk for people to note in the future. I kept the RSB btw as part of my wall of shame. I also have a mangled STi BBS wheel in the collection.

I love the Whiteline set I have installed. It's beefy. And so far, combined with the Eibach kit has proven to be quite the combo. I just have no where near as much mileage on them compared to the parts that failed. I created "how-to's" for both in the DIY section of the forum for those of you interested.
