I just received my Stillen sways and will be installing them this week. Stillen's instruction page suggests using the middle setting for both front and rear. I will post my opinion after the install. Tokico d-specs will also be installed at the same time. Will let you know.

Let us know what settings you put the Tokicos on as well.

I had Woodland's Performance Suspension install the
sport tuned suspension on my sedan last Saturday. While
they were at it, I had them switch my front Stillen sway bar
from the stiff setting to the softest. The car handles great
and feels a bit more balanced. I love the new sport
suspension. It rides every bit as smooth as the non-sport,
but more aggressive in the turns. BTW It took Woodland's
Performance Suspension 1.5 hours to do the install, Infiniti
wanted to charge 6 hours labor, my local CrossCountry
Auto shop down the streed wanted 4 hours labor. The
installer stated that the G35 had the easiest suspension to
work on and wished the Hondas and Subaru's were as easy
to work on.

Cool that's for the info.

Most cars come with an overagrressive front bar [to insure the understeer process] that tends to wash out front tires earlier than necessary.

This would be correct if we were talking about simply adjusting the stock bars. The Stillen bars tend to shift the car from an understeering balance to a neutral balace when set on the same setting front and rear, at least for my sedan.

If you mount wider rear tires, that's going to shift your balance back to understeer. Different spring rates than stock can also shift the balance. Just be careful to not set a street car with too much oversteer; you might find a nasty surprise in an emergency situation. The VDC will keep this in check to some degree, but a neutral car is a better target.

I agree racer X. I actually just got my Tein H-Tech springs in.

Members must remember that a dry tire can support 0.9G whereas a tire in the wet cannot.
Setting your car to neutral dry will be quite dangerous in the wet. Regardless of the width of rear tires.

I always tune mine so that a [right or left] turn from a stop sign at WOT start [with the Viscous LSD] in the rain, hangs the tail out enough to help the turn but not spinout into over steer. This happens to be about 40 lb/inches for the rear bar with 123>200 lb/inch rear springs on my Q but the G will be different due to lighter rear weight [-20%], [more gear multipled torque > +13%], etc.
MY 40 lb/inch rate is roughly half of the STOCK 70- 80 rate of the G so be careful as the G is already aggressive and the Stillen +35% [equals a rear rate of roughly ~~ 110 pound inches]
You must tune your own car to fit you and your skills AND warn others who might drive it that is is different especially in the wet!

It's a shame some one hasn't invented an inexpensive aftermarket dual REAR bar [soft and firm] system that could be remotely engaged to fit the weather. Something like 40 lb/inch and 110-120 lb/inches...............4 steps inbetween would be better.

 

Race cars have adjustable rear bars where the driver can compensate as the 150 pounds of rear fuel gets used up and the tires get worn and hard.

Yet you never hear of anybody adjusting their bars to fit changed situations [harder used tires]..............full gas to empty is a 7% change in rear weight on the tires that alone will change the under/oversteer ratio by at least 3-4%.
Half worn harder tires may have 3-5% less sideways stickson depending on temperature.

But that [TEMPERATURE] of the tire is complex, Careful the colder the road gets as you approach the plastization temperature point the Summer tires can change 20% from 100F > 40F.

Big heavy subwoofer and trunk junk?

 

Hehe I agree. I don't drive my car in the rain usually.

Sorry to bring this old post back, but looking at the fact that so many people on this thread has the stillen sways. It would be wise to ask my question on this thread. I wanted to ask if its ok to use the oem bushings on the stillen sways or i should get new bushing? Because i heard stillen doesn't come with its own.

 

While I was at Stillen a few weeks ago, I asked why they do not include polyurethane bushings. The sales person replies it is because the Stillen bars have the same O.D. as the stock bars and get this, the bushings on G35s are not old enough to require replacement. Lame. These cars have been around long enough to rack up some mileage. Some people have experienced failure of the stock bushing with relatively few miles on them.

I don’t think any company has a poly stock style replacement bushing yet. A while back, someone here checked with Energy Suspension, the leading supplier of poly bushings. At the time, they had nothing to fit the G.

You will have to reuse your existing bushings or buy fresh stock replacements from the dealer. At this point, I don’t believe you have any other option when using the Stillen bars.

 

Actually we've had oem poly bushing from prothane for some time know. Here are the part numbers and where to get them from. All G's and Z's use the same sway bars.

(2005 sedan's and coupes with the sport suspension use a stiffer front and rear bar setup, it is unknown at this time if that means thicker bars or a move from hollow to solid bar construction. I will be going to a dealer with a dial caliper to find out when I get a chance.)

I don't have enough milage on my car since the Stillen swaybar install to
give you a wear analysis, but the fitment itself was very good while
using the stock bushings and mounting brackets. I don't foresee it
becoming a problem, but down the road I may need to replace them.

 

well the mileage on my G right now is around 13000, Do you guys recommend me using new bushings or just go with the old ones for now?? I dont think thats enough mileage for the stock bushings to start wearing out.

 

I think you're fine. but if you're ****, you could inspect it. Do you have any
noise going over large bumps or when your car is turning quickly? If not, you're
probably okay. It might not be a bad idea to inspect and re-lube every 15k miles
or so. I think I can go 20k miles without re-lubing it. will see.
