I would like to know, that to get the most out of an adjustable rear sway bar should it be level with the ground?

 

Let's try a different angle. How does shorting or lengthing end links effect the rear sway bar.

 

Shorter makes the bar stiffer. Longer makes it less so.

 

but what are you trying to do? Crashtons answer isn't correct. Changing the end-link LENGTH may or may not make the bar stiffer, it depends on some other things...

Let's back up a bit. The rear sway helps with wieght transfer during turning. Going to stiffer effective rates moves more weight from the rear to the outer front, reducing understeer.

So, is your car understeering still? Have you found the best hole position for your rear bar? This is the biggest "lever" you have for tuning the rear bar.....

Now the angle of the bar relative to both the ground and the rear trailling arm is a much less "strong" lever to work with. But very few people could even feel the difference. Mostly, you want to set adjustable end-link length to 1) prevent the bar from hitting anything as the suspension goes through it's travel and 2) take out pre-load from the bar when you corner balance.

Also, keep in mind that relative tire pressures (rears a bit more than you normally do) will have the same effect on weight transfer as going a little bit more stiff, so when you're asking about end-links and the like, make sure you've settled on what tire pressures you like the most first....

Anyway, the defening silence you hear is that there isn't a right answer here, and that you're asking about a slight tuning bias that is way down the list of handling changes that you can make.

What I was trying to say was....

If the end link is close to the rear of the bar. As in the last adjustment hole the bar won't be as stiff. If it's in the adjustment hole closest to the front of the car it will be stiffer. I wasn't saying that changing the length of the endlink would change stiffness. Stock endlinks aren't adjustable on my car.

Guess it was too late for me to post. I shoulda been in bed.

 

Want the same end links used in series such as Grand-Am? See DMH Motorsports for PowerGrid end links.

 

You should replace both front and rear at the same time for best results... Otherwise, your front bar will still have preload = not optimal performance.

 

i HAVE AN ADJUSTABLE SWAY BAR AND END LINKS. And I notice that the sway bar is not level with the grond or the trailing arms, just as was the stock sway bar. And I was wondering that if I make the bar level will that make the bar even stiffer?

 

The answer is no... It's another spring - the bar twisting changes the spring rate... The level of the bar makes a slight difference - a 90* difference between the endlink and the bar will make the response more linear, however, instead of some other response curve. But, it's also relative to the other suspension components. The only difference is IF the ends of the bar are NOT in the same position. In that case, you have preload.

If you want to adjust it to make it linear, look at our endlinks...

 

Thanks Alot

 

now that I have settled on a good ride height for my MCS I'm ready to replace the end links with adjustable ones. What is the installation procedure? Remove the old ones, level the bars and simply install the new ones and adjust them in such way that the bar ends stay level (horizontal?) when the car is on the ground?

EDIT: never mind, I re-read the "a 90* difference between the endlink and the bar" comment
