Sorry I had forgotten about this thread for quite a while. Easy conclusion is that the Circuit Sports endlinks from CZP are total cr@p. After less than 1 K miles the car sounds like a 30-year old pickup truck, and I'm embarrassed to drive by people in my WORK parking garage, or have anyone ride in the car with me. Funny how something so simple can really f#ck up an otherwise enjoyable car. To make matters worse, Coz at CZP couldn't give a rat's @ss that I was unhappy with this purchase, but that's OK, because I bought my Akebono big brake kit from Z1.

So, the stock 50K mile endlinks have been back on the car, still not nearly as noisy as the almost-new CZP cr@p, and I just got a great deal on a set of Powergrid endlinks. Buy junk - pay twice.

 

Bumping an old thread.. Just curious, what kind of sound was it making? Can you be a bit more descriptive?

 

Squeaks and creaks. Why should there be any noise at all? Just part of the deal with open Heim-joints, regardless of brand. Also lots of knocking sounds, but that was due to the cheap hardware which CZP included, and upgraded hardware, which might have stayed tight for more than a few hours of driving time, would have made a big difference.

 

Low speed clunks, and plenty of them. I eliminated the majority of the clunks by tightening the bejeezus out of the sway bar connections, but was still much happier once they were gone and I was running on Powergrids.

 

Good to know. Thanks for the feedback.

 

I want to bump this one more time. Earlier in this thread this link was posted: http://www.350zhatchshocksandmore.com/endlinks.htm

It no longer works. I know i checked it out sometime in the last year and it was working. does he still make products? Im in the market for some endlinks and hatch shocks, was hoping he was still around.

 

I'm sending him a text, I know him. See what he says

 

Thanks, I appreciate it

 

humm, works for me....

 

Not to beat a dead horse here, but I'm gonna bump this old thread to also share my experience in case anyone is considering these Circuit Sport endlinks to save a few bucks: don't.
They look really nice and sturdy out of the box, but their so called self locking nut is anything but. I had them installed professionally at Hotchkis in Santa Fe Springs here in so cal along with some sways. Like everyone else mentioned, after only a few days and normal driving it was clunking horribly, specially the front. I was warned by the installer that their heim joint design tends to be noisy and was sort of expecting it, but this clunking after only having them on a couple of weeks was horrible. So i had them checked and the "self locking" nuts that attach the end link to the swaybar was completely loose, halfway off the screw. Re-tightened them, and within a few days, same thing. Tried it a couple more times with no better luck and finally gave up. Ordered some powergrids. What a difference! Quiet and smooth as the stock sways. Now I can finally enjoy the new hotchkis sways, which by the way are awesome. If avoiding a noisy suspension is a priority when upgrading, then the powergrid's booted design is a must. They cost more than twice as the Circuit sports but it is WELL WORTH IT.

 

Links is dead. But if these are stainless finished ones, I've had unpleasant experience with them. They stripped when torquing to spec. Had to mangle them to set my sway bar free. The metal felt very cheap and soft. CZP did nothing for me.
