How much of a difference does it make with this sway bar setting?

I put a pair of UUC Swaybarbarians on last December and they are matched to a KONI STR.T and ZHP spring setup. The front adjustable links have been backordered since December so I have the stock endlinks holding that bar on the "full soft" setting since they can't fit the "full hard" setting.

How much performance am I missing as a result of being "full soft" with this setup?

Full hard would give you +7hp at least

You're right. Make an adjustment. Try it for a while. Tell us what you think. You're a big boy. Act like one.

Are you stupid? I said the part was backordered. Don't you think I would have figured it out myself if I had the part?

It's a very simple question for someone who has experience with adjustable links. If you don't, then you be a big boy and don't respond. Comprende?

My car has an adjustable front swaybar and I can engage either setting with the stock end links. Is there some stupid interference problem with your car/swaybars? You know a swaybar pivots in the bushings, right? Unless there is some stupid interference issue, you should not need adjustable end links.

I've used adjustable swaybars in my road cars and race cars and never needed adjustable end links to adjust the stiffness. The main reason for adjustable end links is to eliminate pre-loading the bar big boy.

I'd have given you a better response if I knew how to answer your question but I don't. You're asking how much performance you'll get by moving to a stiffer setting on your swaybar... the answer is none. You'll just get a stiffer swaybar. Will this stiffer setting make your car drive better? No idea. No one can answer that question for you because we don't know how your car drives currently or how the rest of your suspension is set up, you'll just have to wait until you get the part and try it out.

I'd find some article on swaybars and how they influence handling but I figure you already know.

Full soft is what you want unless you've got your alignment or spring rates set for crazy loose in the back. Full stiff is going to cause a LOT of understeer.

I thought the stiffer you went in the back with the sways the more likely the car would fishtail unless there was a camber adjustment to compensate. Do I have this wrong?

Tremendous performance loss, especially on a 325.

Let us know when you get the links, should be good for AT LEAST 20 seconds around VIR full course.

I had a feeling there would be some type of handling loss because quite honestly the car is not as stiff as I would like.

Bavauto lied to me and said you can use the old links. You can use them but only on the soft setting.

UUC is the worst company to deal with because they don't even know when their own products will become available. I have the Swaybarbarians and the adjustable rear links but am only missing the front adjustable links and I feel like they are the "weakest link" in this setup.

I guess what I meant to say when I said performance was "how will my handling improve."

i had the UUC bars in the past. as for setting up the front bar stiffer, i personally like it. but that was how I liked my car to handle. you may not like it. but does it make a difference using the other holes to adjust it's setting, yes.

as for the adjustable front end link and not being able to install without them?? i agree with Geo, not sure why you can't. the adjustable fronts aren't needed. in fact for how they are used, you only need one not a matching pair. unlike the rears where the adjustables are used to adjust for clearance.

Just because someone knows how to post a video to Youtube, it doesn't make them an expert or even knowledgeable on a subject.

Swaybars do NOT reduce load transfer (or weight transfer if that works for you). In fact is speeds up the load transfer.

Load transfer is a function of lateral acceleration, weight, center of gravity (height) and track width. The ONLY thing a sway bar affects to any degree at all, is perhaps CG by reducing body roll, but that is negligible in the equation.

A swaybar is really a spring (torsion bar) that only comes into play when the suspension on one side of the car is doing something different from the suspension on the other side of the car. It does affect understeer/oversteer, generally as described in the video, but that's about the only thing that moron gets right. The rest is monkeyshines.

The advantage of reducing body roll is to keep the car out of bad parts of the suspension geometry, most specifically, camber curves.

For those who really want to learn about suspension and what is happening, I highly recommend read one of several books on the subject. My bible on the matter is "Tune to Win" by Carroll Smith. I highly recommend it.

I have the TMS bars on my ZHP with stock springs and Koni FSD... No real need for an adjustable end link unless you go lower.
Why are you not able insert the end link into anything but full soft?

The ZHP's bars are already stiffer, so how do you like the TMS bars?

stiffer swaybars compared to what? actually they're even smaller than other early ZSP bars.
