Installed RacingBeat Rear Links, ..goodbye TwosRUs Options

[azian_advanced]

So here's the story. As i was in the middle of upgrading my suspension from teins to even better teins, i had sheared one of the studs off of the TwosRUs links because it had fused with the sway bar. apparently links should always be greased up since they swivel and rub with the sway bar while going over bumps so i can imagine the heat or friction occurring and cause the bolts to seize. so instead of ordering another pair, i decided to try something else. after a quick search, i found out a couple of members are using racingbeat rear links off of a 90-97 miata without problems.

After a quick comparison between the two I have to say that not only are the RacingBeat links more affordable than the TwosRUs ones ($59 vs. $75 for the pair), but they're imo beefier and better designed. the studs don't have spherical joints unlike the TwosRUs links and instead have urethane bushings so it provides a stiffer connection with the sway bar and the struts. these can also be adjusted in length just like the TwosRUs links.

..so if you're going to upgrade springs and/or rear endlinks, go for these.. just make sure you grease all the bolts and between the washers and swaybar for easy removal in the future. Now I just need to find similar ones for the front...

one argue that you need spherical end links as to where the racing beat is just plain bolt on. so who is right? yes I read with racing beat it wears all other parts alot faster. that with spherical end links you put the stress on the sway bar it self as to with racing beat you put stress on the shock.

when i think of it does the sway bar even move much at all??? if so how much??

ahh found this link. the rear suspension on a subaru is the same as our FWD celica's and the same as gt4 celica's. read the first post on this page as written by a suspension company the difference between poly and spherical end links.

also another subaru website:

e offer several brands and styles of endlinks. I've sold a whole lot of endlinks and there have been happy customers with every brand and style we sell. Endlinks are a part that can be designed and built in very different ways each having its own drawbacks and advantages. Up until recently the two most popular styles were spherical bearing and urethane bushing endlinks. Both of these designs have issues. Spherical bearing endlinks are known to make noise in some cases. This is usually because dirt has gotten into the bearing. Urethane bushing endlinks have also been known to make noise in some cases. If a bolt doesn't pass through them at a 90 degree angle it puts stress on everything. Other types of endlinks allow free movement, but urethane endlinks resist anything that is not 90 degrees. In many cases this is not severe enough to cause binding and noise problems, but it is definitely a possibility. The other problem with urethane bushings is they are soft. They flex around quite a bit which puts a buffer between the swaybar and lower control arm. They don 't allow the swaybar to do its job as quickly or effectively, so they don’t perform as well.

The new style I have been running and recommending is called a ball link. Whiteline started offering sealed ball link endlinks in 2010. This style of endlink brings together the best of both worlds. They perform significantly better than urethane bushing endlinks since they don't use spongy urethane bushings. They also fit better than urethane bushing endlinks since they allow free movement, but unlike spherical bearing endlinks they don't make noise. They cost a little more than urethane endlinks, but the difference in fit/performance is well worth the price.
