no more evo swaybar

[coz]

another idea

would it be possible to stack a second oem swaybar on the first one?. i'm sure there is an ample cheap supply of these. just throwin it out thereopcorn:

 

[MMcc]

MMcc - Mike, As many times as you have installed this swaybar on an RT, do you usually remove the Frunk, or just loosen things up enough to change out the bar ?

I found that it was simpler to have a friend gently lift the trunk after removing the bolts. Taking off the trunk was not necessary. Bar is still " for sale" as I have not reinstalled it yet.

i understand completely what you're saying, and the amount of work it would take to mod the bar would not be worth it. looking at it today, the stock swaybar looks kind of thin and wimpy anyhow:yikes:

There is a very noticeable difference in the thickness. The EVo is thicker than the stock, and offers two input points for a stiff and then a stiffer ride. Although I did not measure the EVO, I can put my caliper on the EVO to get is dimensions if you like.

spyder stryder, You know your stuff, nice write ups and great info. Now that the Evo sway bar is history there is currently no plug and play option to change the OEM sway bar. Pity. We still have the option to change the shocks with offerings from Elka, Fox, Progressive and others though. You said when we order a set of shocks to "Just make sure you get what you need on rates & shock valving". I understand that this will be based upon vehicle weight, rider and passenger weight, and riding style, but given that we know this, how do we specify the spring rate and shock valving we need? Could you please expand on this a bit?

Also what is your opinion of the stock shocks vs performance shocks? It's a large investment for a set of performance shocks. Can we expect to see a significant improvement in suspension performance? If so which type of performance shock should we be looking for given those that are currently available? Elka alone has numerous options. Do we need the more expensive offerings or will the lower priced alternatives do?

Sorry for all the questions but your unbiased expertise in this area is very valuable and your opinions would be much appreciated. Answer only if you want. Thank you.

Ok, i'am not telling you this is what you need.Lets say you call a shock spring supplier ( no names here) so as not to offend anyone & there be hard feelings.
The guy tells you he thinks it best to go with a pair of 275# springs with a pair of 50/50 5 valve shocks. Just ask him to please check the spring rates & make
sure the springs are a matched pair.As i stated before if you do not check them they could be a different rate than marked from the spring manufactor. As for
the shocks i would say that they will have the valving that he recomends. This is his job & his rep. so he takes pride in his stuff & wants it right. The spring
manufactor does also but there has been a lot of slip ups on those. You are at his mercy & you will have to trust him.The only way you will know what you have
is to locate someone with a shock dyno & a spring rater so he can check each to make sure everything is in specks.If the shock guy finds out you did this then
he might be upset or might say hey glad you checked them out. Just let him do his job. If you are happy with what you bought he will be happy. If you like the
products & the effects from them & send him business you will make his day.You take care of me i take care of you deal.
If you are shooting for performance handeling the aftermart shocks win hands down everytime.If you want to correct the excessive lean the #1 package should be fine.
On the anti-roll bar don't give up on those just yet i think they will be back soon. Bottom line is if everyone knew the rate on the springs & bar along with the valving of
the stock components then received a print out of the rates & valving on the new stuff that would be great.

thanks cole

no need to measure it. i haven't seen the evo in person, but you can tell just from pics that it's much thicker than stock. i didn't realize it had two different settingsopcorn:

Yes it has two points that you can attach for a stiff (little more than stock) and extra stiff ( really firm for agressive driving)

More great info, thanks! I've always just assumed the spring rates were carefully checked before shipment on high performance shocks. I thought that this kind of fine attention to detail is one of the reasons that the cost is so high. It's also disconcerting that the springs may not be matched side to side. I had no idea that there was a possibility that this wasn't tightly controlled between the spring manufacturer and the shock manufacturer. I assume you've seen some disturbing discrepancies or else you wouldn't be alerting us to this. This could be why some people are so pleased with their shock upgrades while others are not. Like you say we are at the mercy of the suppliers to get it right.

Eco sway bar for RT

no need to measure it. i haven't seen the evo in person, but you can tell just from pics that it's much thicker than stock. i didn't realize it had two different settingsopcorn:

Perhaps the bar for the GS/RS has two mounting holes but the one I purchased for the RT only has one.

Here is a pic of mine. The inside hole is the stiffest setting. The outside is less stiff.

If you reference "spyder talk " evo swaybar you will see that the RS/GS bar does have two mounting holes. The RT bar only has one. Its location is the the same as the inner hole on
RS/GS bar. I did some quick measurements and it looks like the RT bar will fit the RS, you will just have the stiffest setting.

I have the Evoluzione bars here and comparing RT to RS, one on top of the other, they are different - in my opinion the RT bar will not fit the RS

I stand corrected. The numbers are different so they must not interchange. Thanks

Would you please check the size of the Evo bar & post the measurement?

Thanks

Cole

Please do that
Thanks

 

[NancysToy]

Please remember that the Evoluzione RT and RS anti-sway bars are not only different lengths, but the RS bar has two link positions and the RT has one, plus the RT bar is thinner, much the same as the stock bar, while the RS bar is noticeably heavier gauge than OEM. It would help if people started referring to the model designation in their descriptions, questions, and measurements. Another useful measurement would be the short arm length, from the main bar center to the center of each link hole.

Evo Bar dimensions

Please do that
Thanks

Ok, that was hard to do on crutches, getting up and down was a bear but got the measurements.
9/16" or 14.4mm or .57in in thickness measuring at the middle of the bar with a calibrated digital caliper. You owe me a beer

Cheers,

Cole

Well a lot of people assume the same thing. An a lot of the suppliers will sware their springs are
dead on specks or no more off than 2% on rate & free height. At one time or another i have had
my hands on about every brand coil & leaf spring that you can buy in the USA.Have found quite
a bit of them off on rate,some 10-30#,some as much as a 100#. The shock guys are at the mercy
of the spring supplier but i think he should check the springs & use a matched set.The springs are
marked on the end but don't bet you life on what you see. Ok,lets back off this spring stuff before
i get in trouble. A guy would not ride around with 20# of air in one tire & 10# in the other.

Thank you,sorry about you having to go to the trouble while being injured.
Now that makes me feel bad,probley want sleep tonight.

Hi Scotty

I have recent stock (designs of the Evo RS bar did change some time ago) of both RT and RS Evo swaybars and while I don't have a micrometer the RT bar is the thicker one by far. I just took them both off the shelf and clearly the RS is the thinner bar and its longer than the RT. Around 15mm for the RT ones and 12.5mm for the RS one (measured with a ruler).

Thanks, that's good to know. I know the first RT EVO bars were reported to be the same diameter as the OEM bar, but stiffer because of shorter link arms. It is possible that the stock RT bars are thicker than the RS anyway? What we need is good dimensions for both models, for both stock and EVO bars, then we will all understand what is going on. This thread gets muddier by the minute.
