first off, i have a G coupe, and it tends to understeer quite a bit more than a Z. now with that out of the way ......
i have an order placed for a rear cusco bar. the reason I did this, is I want to set it up for less understeer and more towards drift. granted i only go to drift sessions once a month and spend much more time on daily driving.
right now i have a chance to get the whole kit (f/r) rather than wait another month for the rear...
what I'm wondering is how much of a difference the front bar would make in daily driving and in drift (taking into consideration the G's stock handling).

 

F - I'm new to the 350z/G35 family ( just got my coupe ) but here's my input from years of racing ( autocross & drag ). Most cars R set up to understeer because typical drivers panic when the tail hangs out ( oversteer/drift or "fishtail", as us old farts call it ). Sounds like U & I R similar as I learned to drive on dirt/gravel roads where the back end always came loose. Anyway, is the Cusco rear bar adjustable? If not, I'd GUESS that the Cusco set ( of both bars ) is designed to give neutral handling. This will get U closer to your desired drift status but not quite there. I had a set of Intrax bars on my GS400 but the rear bar was adjustable simply by moving the position of the link into 1 of 3 holes. This allowed me to dial in the suspension & to adjust for any changes in the car ( I had 200#+ of stereo equipment in the trunk so I oversteered enough already! ). As I'm looking to modify the suspension myself, R there any other bars on the market that R adjustable? Good luck with your quest!

 

Mean Gene:
Just looking into the swaybar options for the Gc myself. Four options that I know of, Cusco, Nismo, 350EVO, and Eibach. This thread mentions a couple links to places to buy these at. The Cusco's and Eibach's are both adjustable (as seen on Gruppe-S.com)

Fiddler:
IIRC, wouldn't softening up the front swaybar as well decrease understeer?

 

mines makes a set as well i believe

 

I am also a regular autocrosser. While I have my SVO specifically as the race car, I do plan to bring out the G every now and then. I have been racing a Miata for the last 3 years and I learned a lot about my driving style and the car. I like a car that is perfectly neutral. I've had the car loose and it has been difficult to control. This pushed out my times. I've had it pushing hard and again it pushed down my times. As a driver for my personal driving style, I just drive best with neutral balance. That is in constant cornering I can control both ends of the car by puching down or lifting the throttle. I went as far as having a custom front sway bar made to get the car perfect. Keep in mind that this is individual for every driver. Some like a loose back end so they can drift through corners. Others like it tight so they brake later and use the push to scrub off speed further in the corner.

Our cars, of course, understeer for safety. Knowing this, I took 2 courses of action to correct it. First, I made a deal to swap the front 225/45's as new for a set of 245/40's. This worked out great because the local Michelin warehouse is doing a 1 for 1 swap for free. This will even out the contact patch area on both ends. More grip on the front means less oversteer. Keep in mind that if you upgrade your tires to a 245/275 combo, the tires will make it understeer even more since you are adding more additional grip to the rear than is added to the front. This is why I may upgrade to 9.0" wheels all the way around, but keep 245's.

I know that setting the rear will be more important than the front to get the understeer out of it, so I intentionally chose to go with the Eibach sway bars. There is a little noticeable body roll from the factory, but it doesn't that much stiffer of a front bar to correct it. Although they are the cheapest(about $350 from Todd at Discount), having a smaller front bar than other kits was the big factor for me. They are adjustable, so I can tune the car. If I can't get the car balanced, I will go to a different set or have a custom one made like I did for the Miata.

 

are the Mines set adjustable?

 

I just had the front tires switched today from 225/45's to 245/40's. There is a little more noise and the ride is a little rougher. I have will to drive on them a few days to see if this changes as the tires relax. There are no tracking or tramlining issues. Initial turn-in seems to be slower, but mid-corner turn-in is a lot sharper. If definitely took some of the push out of the car. My sway bars should be here any day.
