Strongest rear sway bar end link? I broke 3 sets...
I just broke my third set of rear sway bar end links. I broke the first set (Hotchkiss end links) when running Hotchkiss springs, sway bars with stock struts. After I blew out the stock rear struts, I got Mann-Engineering AST coil overs and got Whiteline end links (because I heard Whiteline end links were great) and kept the Hotchkiss sway bars.
With this set up, I broke two sets of Whiteline rear end links. The first set after about 6 months (while on track at Laguna Seca), and the second set after ~ 1 year (I have no idea when exactly). Whiteline replaced the first set under warranty, and I could get them to replace the second set, but I just want to find an end link that won't break! I only do a ~6 track days/autoxs a year. I am running ~1.5 inch drop. I saw Perrin put out the SS XD Spherical Bearing Rear Sway Bar Endlinks for ~$500 (seems expensive) (http://perrinperformance.com/i-14660...-fr-s-brz.html) Anyone try these? Anyone know of anything really strong? Pictures of the break:

I dont know why you have broken 3 set of end links because they are not supposed to be broken that easily after properly adjusted.
But since you ask for the best one, I would say SPL. http://www.splparts.com/products/spl...s-brz-wrx.html

Thanks, those do look great.
I did adjust the swaybars the first time, so I thought I may had made a mistake which caused the end links to break. The next two times they were installed I had a professional race shop (both authorized Whiteline shops) do everything. I am starting to think that it maybe the Hotchkiss sway bar design that doesn't align with the rear control arm properly, which may cause extra stress.

What size sway bar are you running? Maybe going smaller and letting the coilovers do their job a bit more might help.
Also - did you put in LCAs? Which ones? |

Where are they breaking at?
http://www.aurorabearing.com/index.html You should be good with a military or aerospace series. Many companies use their parts and sell under their own name. Not sure who actually carries their parts, let us know if you find a place or what you decide to do. |

I am running the SPC adjustable lower control arms, but I only installed those after the second set broke. They were installed the same time as the latest Whiteline end links.

The Hotchkiss end links bent the the bolt that linked the end link to the LCA so much that I had to cut is off with a dremel. The Whiteline's broke in the same place, shown below. All times the right side broke.

Some LCAs have a bit of different geometry. GTSpec, Stance, etc. I run GTSpec. They have a bit of an angle to them. Helps with lowered cars in some cases.
Yours? vs Anyway - just seems weird that there is that much force on that one side. Certainly beefier links may help but maybe something else is going on? I also have a GTSpec rear sway bar braces Well, that's all I know and it probably didn't help much! Good luck with the issue |

I've noticed that even an entirely stock rear suspension will cause the portion of the endlink connected to the LCA to twist a bit once mounted. luckily the stock uses rubber bushings so it does not break.

I'd go with these if you intend on keeping the rear sway.

If it's always one side consistently breaking, the issue might not be the end link but the positioning of the centering rings on the sway bar. Have you checked that the centering distance is the same on both sides?
