suspension Help!!!

So it just rained here in Il, and I find that my g35X back end coming out each time I take a corner with a little throttle. Does it have anything to do with my sway settings? Or is it because of my tires. My sways are full stiff in front and middle in the rear. I have stock rims with all season tires. Also I have the hotchris sways.....

Interesting.... I just ordered the Hochkis Sway Bars and I'm trying to decide which setting to use on the rears. Can you tell us which setting you used?

Now to your question: There are many things that will increase the car's tendency to oversteer:
- front sway bar is not stiff enough
- rear sway bar is too stiff
- front tires are under-inflated
- rear tires are over-inflated
- rear tires are worn too badly to grip well

If you're using the Hitchkiss bars, and all other factors are determined NOT to be causing your oversteer, I'd suggest backing off on the adjustment for the rear bar. I believe the stiffest setting is outboard (closer to the ends of the bar), so moving the mounting point inboard could help.

So.... which setting are you using?

All of the things you mention factor into it. The traction of the tires you have, wet roads, and your sway bar settings. Since it's the easiest (and cheapest) thing to change, try setting your rear sway bar to the least stiff setting to reduce oversteer. Only try one change at a time, to see what it feels like and what is working before trying something else. Experiment to see what gives you the handling that you like for your driving style.

All season tires are not performance summer tires. That alone can make a world of difference.

Remember that the Infiniti AWD system is rearward biased, so you'll get higher slip angles in the rear as a result. Adding stiffer swaybars will only accentuate that. Try setting the rear sway on full soft or disconnect it completely to see a difference.

Definitely sounds like an issue with tires then. How much tread do you have left? How many miles have you driven on them?

Just a clarification on this post; to soften the rear bar you would choose the holes at the end of the bar not the inner holes.
You may want to do nothing more than adjust your driving style in the rain. I can see all you speed racer types driving your G's out on the street like your on a closed road course. If you are sliding out the rear of your car in the dry or the rain, you are driving too fast!
That's it...I officially sound like an old man!!!

LOL! Yeah, I hear the OEM Dunlops are pretty useless for real performance and for snow. Kind of an in-the-middle compromise that gives you the worst of both worlds

I'll be getting some nice summer tires when these burn off. For winter I'm nearly ready to get a wheel/tire package with some aggressive snow tires. No doubt I'll be much better of on both ends.

Read through the whole thread, and I agree with OB G on all accounts. Yea, mike, you sound like an old man, but it's completely warranted. You shouldn't be sliding around if you're not trying to. And OP, get new tires. I'm 110% sure that's your problem. No name all-seasons means trash.

Nankang Milestars look to be very cheap Chinese Tires. I think you will find a world of difference with a set of quality performance tires. Good luck!
