Does anybody think that the stillen sway bars on med settings for both F/R is too close to stock. I have an 06 coupe and for some reason I feel like the med settings is too close to stock. Does anybody have them on the hard settings and can share some info. How it handles and if there are any problems with having them on that setting, and how much stiffer it actually is. TIA.

 

My first setting was stiffest in both front and rear. This was a HUGE difference over stock! Q45Tech recommends using the softest setting up front to eliminate the understeer. When I had my Sport tuned suspension installed, I had the installer change the front bar to the softest setting. The car is very balanced now.

 

so you have the front on soft and the rear on hard?

 

In most of the cases, IMO, the best setting is all the way stiff on the rear, and medium on the front.

 

mine are on stiff front and rear...but i also have larger tires front and rear

 

sway bars are hard front/hard rear on 20's and tein coil overs.
with the 20's and the sway bars i had a lot of oversteer. (no camber kit post teins so currently not much oversteer)
cato/wa2good do u think i should go soft or medium in the front?

 

I also have larger tires on 20 inch rims. So do you guys think the best settings for this would be hard rear med front or hard for both. I am looking for both performance and safety, dont want my car to be oversteering all the time.

 

I am pretty happy with soft on front and stiffest on rear. No understeer whatsoever. I would be willing to try medium up front but don't have the ability to change the setting myself. Talk about flat turning...with stiffest on both front and rear it was like the car was on rails. But the understeer was not eliminated, probably exagerrated that way.

 

i like the stiff/stiff its makes the car feel more connected

 

mine's on soft front/hard rear

 

Remember a front sway bar is what creates UNDERSTEER in the first place, so you want the weakest [setting] front bar that will do the job.

Factory usually sets the oem spring rates [as measured at the tire road interface] equal to the weight distribution........THEN installs sway bars to set the ubdersteer ratio.

Change tire brands, sizes, [inflation], and the side wall stiffness changes which affects the [in series] spring ratio by up to 10%.

So there is not one perfect sway bar setting depending on tires and psi and temperature assuming exactly the same loaded weight ----driver and fuel.

Just remember a stiffer front reduces the effect of a stiffer rear!

Don't assume that you can use the same settings with brand new [after 500 mile breakin] tires as you can with worn tires [compound has hardened and block squirm reduced].

 

The first time I was at the track with my Stillen sways I had soft front, medium rear (since this was what everyone was recommending). In my case, this setup still induced too much understeer (245/40/18 front and 275/40/18 rear). Accelerating out of the turn my front end was sliding a lot.

I then put the rear on the stiffest setting, which made for too much oversteer for my taste (end up drifting the car instead of tracking it). So for the rear bar I put the right side on the stiffest hole and the left side on the medium hole (since they are seven way adjustable). This gave me the best setup.

When I put on my Tein Z H-tech springs, I suspect that I will probably need to set the rear on the stiffest setting again since the springs transfers +3% roll stiffness to the front.

I guess the point being soft front/medium rear is a good starting point. You will have to play around with the settings depending on your tire/wheel/spring setup.

 

You did what? You set the right side diff than the left side?? Is this "track" an oval or something?

 

Good info on this thread. I'm going to change my front sway bars to medium and see how the G handles. Still getting used to the Tein basic coil-overs. I definitely learned how to read the road better. I have a lot less clearance now. Pothole ouch!

^^^dam that looks sick, if you wanna see how the med front and med rear setting feel like before you do it, hit me up. i'm in hollywood but i work in ft lauderdale
