    Whiteline Rear Sway Bar Questions

    Are there two different adjustable rear sway bars made by whiteline. I was under the impression that the 20-24mm was the only one but I just saw one advertised as a 24mm heavy duty one that maxed at 26mm. Can anyone clear this up for me?

    Also, is it necessary to get the upgraded heavy duty mounts? I will unless it is not worth the extra $80.

    thanks

    I think there was a thread about the rear endlinks, try a search. Basically the concensus was that if you upgrade the bar, upgrading the endlinks will allow you to get the most out of the bar, and also will be less likely to break.

    I've got the 20-24mm bar with whiteline endlinks. I'd probalby go with nicer endlinks if I wouldn't have gotten a deal.

    I know all about the endlinks and I am planning on getting the kartboy solid ones. My post had nothing to do with the endlinks, what I am talking about it the heavy duty mounting kit that replaces the stock mounts. I was wondering if it was necessary or not.

    Most people don't with the 20 - 24mm Whiteline bar. Don't know about that big one though! A few people have had mounts break - not sure why - and then replaced them with the heavy duty ones.

    I would do the mounts and endlinks at the same time to really optimize the adjustable rear bar...it isnt "necessary" but neither is upgrading anything else.. The stock mounts are rubbery..you wont get the maximum benefit of a stiffer/adjustable bar unless the mounts and endlinks are also more heavy duty.

    The bar comes with new bushings for the mounts (has to). Upgrading the mounts won't do anything except possibly be more reliable.

    The heavy duty endlinks will allow the sway bar to act more quickly, because it will not compress/deflect like the stock one. The end result will be that on the up side the car will feel more responsive, but on the down side overly quick or jerky steering inputs will tend to unsettle the chasis to a greater degree.

    Hi All,

    As you are aware, OE Subaru plastic sway bar end links have relatively high compliance (flex) in both the plastic link and the rubber bush. Our heavy-duty rear end links (part# KLC19) are made from solid spring steel with a polyurethane bushing, giving much quicker responce from the sway bar. These work well with all sway bars, starting from 13mm (yeah I know, but that's what the very early models came with) all the way to our 26mm XRD sway bar.

    Now to the original question of this post.
    We offer a large range of adjustable sway bar sizes for both GC8 and GD WRX's, starting from 20mm, through to 22mm, 24mm and all the way to a hybrid 26mm XRD version. Please check our catalogues or contact sales for more info/part#'s.
    The heavy-duty rear sway bar chassis mounts (part# KBR20_xx size) are considered not to be essential for swaybars up to 20mm. They are however recommended for swaybars from 20-22mm and strongly recommended for 24mm sway bars and bigger. Just to put it in perspective, we have seen 12,000km old OE mounts break with only 20mm OE sway bar!

    Trust that this helps.

    Regards,
    Wojtek.

    Perrin endlinks look nice, but haven't tried them.

    If you are only changing the rear bar, just rear endlinks are fine.

    To me, whiteline = cusco. I haven't really noticed any difference between them when looking. Finish might be a bit better on cusco, but functionality they're probably the same. Should be same for wagon vs. sedan.

    I put a set of the Perrin endlinks and sway bar on last week .
    All I can say is wow what a difference.
    The fit and finish is second to none, the endlinks use a bearing rather than a bushing which keeps everything nice and tight, and the bar comes with new mounts to replace the flimsy OE ones.
    They cost a bit more, but I think it's worth the extra $$$.

    The one difference between Cusco and Whiteline is that the Whiteline bar has an adjustment range from 20mm - 24mm in 1 mm increments, and I've been told that the Cusco bar only adjusts from 22mm to 24mm in .5mm increments. Like I said, "I've been told" so I'm not positive on the Cusco.

    I also drive a wagon, and this is what I've learned from my research on the subject...

    There's been some debate over the Perrin End Links. The folks at Kartboy will tell you that they experimented with spherical bearings in their end links at one time, and found them to be short-lived...which is why they offer traditional bushings in their product. I guess it's up to you whether or not you want to pay the extra money and find out for yourself. Also, one non-debatable result of using the sperical bushings is that they provide a harsher ride than links that use an elastomer...like polyurethane...or some form of rubber bushing.

    Front End Links: I've heard of several people that have removed their solid end links because of the excessive harshness in ride quality. I've also heard that they're great if you plan to auto-x. You must decide if you can live with additional harshness, or not. Personally, I wouldn't bother...

    Whiteline vs. Cusco...is like Sti vs. aftermarket replicas. If you're not too caught up in "designer" labels, I don't think you'll notice the difference in quality. Both are good manufacturers. With one, you pay a little extra for the name. I'll let you figure out which vendor that is...

    There is a wagon-specific sway bar from Whiteline. I don't know about Cusco, but I'd guess they offer the same. The sedan bar will fit, but it doesn't fit quite as well as the wagon-specific bar. I'm using a stock 20mm sedan sway bar on my wagon...with excellent results. Only paid $60 for it, too. In my research on sway bars for the wagon, I found many, many wagon owners who were satisfied with the stock sedan unit, which is why I went that route.

    I hope this info hepls...
