I have installed sway bars on my G35 sedan and have it set to medium front and hard rear. I have been noticing that my car will fishtailing a little going over large bumps and manholes when its wet. I did install new tires on my car a couple of months ago too. Do I have the rear sway set to high? Do I need to put the rear back to medium setting to eliminate this? Please give any suggestions.

Isn't this common knowledge?

Setting your rears high will leave little room for difference between sides. Set the rears to medium to avoid fishtailing.

I would only run Stillens on high or Cuscos if I was drifting. Otherwise there really isn't a point.

 

In addition, in general, stiffening the rear suspension in relation to the front (i.e. stiffer sway bar, stiffer springs, shocks, etc.) will result in greater tendency for oversteer (fishtailing). Either set the front to hard to match, or set the rear to medium to match.

Also, you have stiffer springs and an STB which contribute to the overall rear stiffness increase.

 

I am going to put the rear sway to medium on Saturday. I did some research on here and found most sedan owners use the med on front and rear. I am running OEM 350z springs/coupe springs on my sedan. So basically my car suspension is stock. Thanks for your input.

 

You could also try the setting in between medium and hard on both F/R, BTW.

 

Running medium on front/rear now. So far it seems a lot better.

 

I ran med/med on my coupe and it was alright, now its on hard/hard and i like it a lot better

 

im currently running medium all around and it drives great , on hard it was a bit much for regular use,

never tried the first setting yet

 

^ at first had was annoying but now I've gotten used to it
