Sway Bar Summary!
 

EDIT: I don't have a G35 anymore so I don't really check the tech forums anymore. If you have updates for me to add to this first post, please PM me w/ the info and I will add it.

Hey everyone, I thought it would be a good idea to create a thread w/ a summary of info for sway bars. Please add posts and I will try to update this original post with your information so that people can see a lot of info in 1 spot. Hopefully people will do a search and find this thread.

this is interesting. I had a question about sways earlier, I hear that they might cause the bushings and the connecting part to crack? Is there truly any downside to aftermarket sways???

Great idea for a thread! This is all I can add. Feel free to reword. Others may want to elaborate.

Hotchkis

Pros/Cons/Experiences: The bars do not incorporate bushing “stops” to locate the bar. Some people have noticed the bar shift to one side or another. The fix is to purchase a pair of “collars” from McMaster Carr (part Number?)

Stillen

Bushings: None included

Pros/Cons/Experiences: Requires reusing stock bushings, buying new stock rubber bushings, or aftermarket polyurethane bushings.

Sorry I am new to this subject but how much do sway bars help handling and in what respects do they help. Would it be better to get springs or sway bars first? One final questions I have is if I get sway bars are they any possible damage they could cause to my suspension or anything that would void my warranty? Thanks in advance

anyone got pics to go with the sways?

whch sways do you guys reccomend? im not sure how it works :confused: also its for a daily driver

Yeah I 2nd for pics, I'm thinking about picking up a pair.

It took a while to get some responses but I'm glad people are chipping in now!!
I updated the orig. post w/ the comments above. Keep 'em coming!

To answer the question "which sway bar is the best?", there is no 1 answer. That's why I created this thread, so people can compare the specs and comments and decide for themselves.

Having adjustability is the best for sure.

I have a set of 350Evo sways on the way for my sedan.

That picture isn't reflective of the Stillen.. its red now :) I think the yellow wasn't 5 way..

Hotchkis! feel great no problems 100% notice in handling. Ive ran Willowsprings fontana and Laguna seca with them along with many other tracks. But MOD by far

+1 for Hotchkis, You cant go wrong with them, they are probably IMHO the best bang for the buck. I have them as well and tracked the car with them.
