Install rear sway or keep stock?
 

Since I don't have a garage and time currently, I am going to pay someone to install the sway bars. Do you guys think I should keep the stock rear bar or use the one I got from Hotchikis? My car is stock minus a set of coilovers 14/12k or something around there.

I think it depends. Are you changing the front sway too? If so, to what? Hotchkis?

yah, cant tell you cause not sure how the car handles currently and where/how you drive.

hi, without looking, can you tell me if i should get this one or that?

:ugh2:

Keep stock bar. Disconnect it occasionally.

Agreed. Stock rear and the biggest front up can put your hands on lol

i use hotchkis front and G37S coupe rear, the rear hotchkis is WAY to stiff even on full soft. I would stick with your stock rear

Being you have good coilovers keeping the stock is perfect. The suspension on the rear needs to be softer on our cars. Then adjust coilovers accordingly.

I run the softest setting on Hotchkis cause I just don't want to swap back to OEM. But I have adjustable end links to take out some of the bind that happens from after market sways and OEM endlinks. The best option is OEM sway but you can make it all work with have great understanding feel of your car and driving habits by adjusting the front to rear. But my car is a totally different beast.

i had adjustable end links with the hotchkis rear, still found it way too stiff. Once i went square wheels/tires, i didnt like both the whiteline and the Hotchkis bar on full soft. I tried the stock rear bar but with my soft V3 rates, the rear was sluggish. The G37S coupe rear bar is slightly stiffer then the OEM 370 rear, but still softer then any of the aftermarket bars out there. this was the balance i liked

That could be my issue now. I have done so much to the car and haven't tested it yet.

once you get the car back on track and tested, if the rear seems uncompliant and edgy with your current bar, try and source that G37S coupe bar, it compliments a big front bar well since its just a touch stiffer then stock but still on the soft side

okay front sway bar only Monday then. now what am I going to do with the rear bar

Coat rack.

Fancy new pull-up bar.

Pulling this thread back.

Have the Hotchkis bars front and back. The front is planted with the Hotchkis bar and my alignment settings. The rear with with the Hotchkis bar set at full soft. The Z is tail happy. :eek: Had slides yesterday during my trackday. Had one really big that I thought that I wasn't going to be able to come out of. :eek: There was a Mustang that followed me. And he thought that I was trying to drift around the track. LOL :driving: So with what I learned. I'm whiching back to the stock rear bar.

I think you are moving in the right direction. I am still searching for a Hotchkis front bar and a Nismo rear. Seems to be the best balance from the more experienced racers.....

told ya :P

I know, but had to try it. Wanted to see what the Z felled like.

This is an awesome thread guys. Thanks for teaching me something today!

Had an interesting thought. Earlier this week I was working on a friends 2009 g35x. We were intalling new sway bar end links and bushings on the front of his car. Noticed that his sway bar is significantly bigger than the one on the front of the Z. Has anyone tried the sedan sway bar on the z or know if it would fit.

Looking at the thickness of a bar means absolutely nothing.

1. Is it hollow or solid?
2. If hollow, what is the wall thickness?
3. How far from the pivot point are the ends?
4. How far from the pivot point do the endlinks hook up?
5. How thick is the bar (lastly!)

There are other small things, such as metal used, bushings, etc... But those are some very important parts. Geometry plays a far more important part than just thickness of a bar. For example, (and I don't know the answer to this) I know that everyone says that the Hotchkis bar is the thickest, but I believe is it also longer from the swaybar mount to the endlink mount. I have a Whiteline and am VERY happy thought it is "only" 27mm...but it has a much shorter arm length.

What you REALLY need is the motion ratio...IE how many lbs to flex the bar one inch. THAT tells you truly how stiff a bar is. We really need that information to truly assess which bar is the stiffest...
