WTB: Cusco rear sway

On the rear, the non-STi WRX's have a "over and under the lateral link" endlink design. In other words its a horseshoe shape peice. The sway bar flexes and twists like mad under spirited driving and the "U-shaped" end links need to be able to flex. Or, they will bind, cancelling the proper effect of the sway bar.
On the front, you could run an aftermarket endlink, because it is "straight" design. And, on STi's the rear endlinks are also straight.
However, I still recommend not using them. As, they do not flex all that much to reduce the swaybar function. Plus, the most aftermarket swaybars are designed to work with stock end links.
Also, the end links function as "fuses" in case something goes bad and you slide into a curb. Then, the link would snap, where a solid link would cause a whole lot of "bendage" all over.
That's my take on this.

all solid endlinks still have "Flex" in them, the flex is where they bolt up to the swaybay, the whitline endlinks still have rubber (stiffer) where you put the bolt to connect the endlink --> bar, so it will still flex under "spirited" driving, same with the perrin / helix, because the bearings still move... having the "U" not flexing is a good thing, it makes the swaybar react faster, this is the same reason why ppl buy STi engine / Tranny mounts, it stops the Initial Twist which makes response faster when you blip the throttle to revmatch etc... same with a swaybay when you turn the steering wheel,
thats my 2cents, also if endlinks weren't needed, why would whiteline, perrin, karboy, helix, etc. etc. all make them...and gary sheehan uses them on his race car... imo they are very good, I love mine and they aren't that expensive, so go for it

um. since everyone is here....
MRTs any good? is that what i'm looking for? i'm saying yes because it's blue.
Imprezer makes some really good points. But it would seem like they have aftermarket endlinks for a reason.
thanks for the info guys.

Remember this:
There are parts that you need and there are parts you don't need. Sure, you can buy them all.
Flex is flex. Sometimes you want it, and sometimes you don't.

thank you very much. Cool. They should sorta match the CUSCOs... too bad they are sorta ugly.
so i still don't get the difference between the endlinks out there. Aren't they all "solid"?

thanks zoeb. haha. you're right.
anyhoo. i'm just waiting for MPJ to get back to me... maybe i can get a deal with a CUSCO rear sway.
i'm wondering. Lets say we do need some flex... how much stress can the stock endlinks hold? seems like they would snap. heh. pretty hardcore driving ..haha.

And i bet if cusco made endlinks, you'd have them on your car solid or not.

I am not going back on that. When I said that, I beleive I was referring to the chassis bracing, not end links.
This is my opinion on endlinks. You don't have to agree with me. I was asked an opinion and I gave it. You cannot prove me wrong, as there is no right and wrong here.

I don't wanna keep massaging this. I made my point. I have reasons behind it. You made yours. Now, it is his choice what he wants to do.

fancy that.



(Not my car) I have Helix links.
