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...

these are just about removing the purpose of the endlink altogether... they are going to add side to side motion to the endlink... which is not possible in the sphere... there is little to no rotational movement - you might as well just weld a bar between the mount and sway bar... it would serve the same purpose as these endlinks

as far as the distance between the endlinks... it makes absolutely NO difference as to how long or short the endlink is as long as you can get it to fit... the adjustable idea is to remove the preload... which as long as you do everything right, you shouldn't have any anyways... getting the bar to be horizontal as stated is the biggest lead on i've ever heard... its the bolt in the endlink that needs to be horizontal... the sway bar is to reduce side to side motion since the invention of independent suspension.... yes the polymounts will give you a stiffer ride for the time being... but you are going to burn out other parts very quickly including your shocks... you are putting all the stress on the shocks rather than on the sway bar, not to mention your a arm bushings are going to get destroyed as well... this is a cheap mans bandaid to the problem of suspension... put the money down and upgrade the parts that need it... first off... thicker sway bar... the stock sway bar is junk

these are in no way a better upgrade than the twosrus endlinks...
