While I looked up the 350evo website, I noticed that the poly bushings are now optional for the sway bars. Anybody is using those sway bars with the stock bushings? Does it fit nicely or you needed some hacking?
If I go with the poly bushing, will I get noticeable perf improvement? Those bushings are ~$110.
Thanks.

 

Not worth 110 dollars but I know someone who swears by them. He'll be posting soon.

 

The polyurethane bushings are big improvement over the OEM rubber bushings. They are highly recomended for max performance. They are def worth the money. Just sold another two sets of sway bars today. We are fully comitted to providing the best performance for the customer at 350EVO.
Some new goodies are coming!!!!!

 

BJ,
When will the new poly bushings be in for the sway bars?

 

OK, dwnshift, explain to me the difference here. Why are the bushings better with your sways, and can you really feel the difference?? What is there benefit here?

 

bump for answer from dwnshift.

 

little rod.
Sorry for the delay.......
Rubber bushings are much softer than polyurethane or delrin. A softer bushing for a sway bay will have more flex or crush....the bar will move around in the bushings under load.
A stiffer bushing will keep the bar static inside the bushing and bracket allowing for quicker more effective weight transfer through the sway bars.
Yes there is a differnece and it can be felt.

 

BJ,

Have you received the redesigned poly bushings for the sways yet?

 

Will talk to them tomorrow....we have a couple other irons in the fire there also.

 

Any difference from the products Energy Suspension produces?

 

Yes.....I believe the ones that ES does fit the OEM sway bars. I am also sure that the make up or compounds are different. We work with a local company for our bushings needs.

 

Hope it is the problem rear suspension bushings.

 

I have been able to work witht the bushings we have now and open them up. The ones we will be getting will be made with a bigger diameter for the sway bars.....
The other things they are working on are a new..............for better.......and a new.........!
just have to wiat and see!

 

BJ,

Where do the new sway bar poly bushings stand? What sway bar settings are you running on your street Track with the Konis? How is the understeer? Am I correct in saying that if both ends are set at medium the stiffness in the rear will be increased and that will lessen understeer?

 

I'll let BJ comment on the status of the new bushings, as it should probably come from the horse's mouth himself (he's been a bit frustrated with it).

As for the settings, while I do not have Konis, I do run at medium settings on the street, and the car is relatively neutral. So what you are saying is in fact correct. HTH.

 

Thanks John. Are you running the poly bushings or stock with your 350Evo sways?

 

When I installed my 350EVO sways, my stock bushings showed signs of tearing. I wouldn't have wanted to put those things back on because I track my Z quite frequently and it's my opinion that those bushing just can't keep up.

My poly bushings, however, have held up quite nicely.

 

I'm running the poly bushings. When installing them, lube up the bushing with marine grease.

 

I've never heard of a company not including poly bushings with their aftermarket sway bar set. I've heard of poly bushings sold separately for stock sways (Daizen sport tuning).

 

You can buy 350Evo sways either with or w/o poly bushings.
