Steeda Competition Sway Bars - How to best adjust?

[derklink]

Hi all,

Hope this finds you and your cars well!

I have Steeda's dual rate springs and their competition sway bars. When pushing the car hard through corners, I notice some understeer, which I guess is not a surprise given the weight of the front of the car.

I have the sway bars set up in a neutral/middle position/hole front and rear. Contacted Steeda about it and they recommended setting the front bar to the 2nd softest setting. Some internet/YT research recommends stiffening the rear by one hole, instead of softening the front.

What say you?

Thank you!

Hey OP,

Here is a quick guide on addressing understeer

I would try stiffening the rear first if you drive mainly on the street, If you track it it would be a toss up, the good thing is you can experiment. For me the rear is easier to get to for adjustment.

Try both and see which works best for you.

What is your camber ? At a min set it at 1.5. Then start playing with your sway bar settings

A little more description would help. When it's pushing, are you on the brakes, steady speed/steady input, accelerating?

It could be as simple as getting on the brakes later and harder to set the front end.

I’d also soften the front to give back some grip as steeda recommends. Stiffening the rear is an option but generally I’d soften the front first.

Whats your tire situation? Sizes and type?

Thank you all for your quick responses!

I run 305s front and 315s or 305s rear, depending on brand, on Apex wheels. Front negative camber is currently -1.8 but will go to -3 now since I recently corded a brand new Trofeo RS front driver side tire on the outside in one and a half days, while the inside of the tire showed only moderate wear.

I trail break and feel the understeer when coasting through the turn or maintenance throttling mid-turn.

If you are cording the outside of the tire with a 1.8deg Camber then you have too much toe in. Or you are really hitting the turns hard all the time. Get the alignment done correct ( 1.5 deg Camber with 0 deg toe.) Then start playing with the swaybars. This is what I have mine set up. FP track springs, struts and shocks. STEEDA adj sway bars front and rear. I also have the Steeda end links and bumpsteer correction. Now for the fine tuning. Street ront Camber is set at 1.5 deg and toe at 0 deg. and Rear is 1.9 deg Camber and toe at .10 per side. With the front sway bar set at #3 from the end (stiff) and the rear at the stiffest setting. Track set up is front 2.5 -3.0 deg and 0 deg toe rear is the same as the street set up,e
with the sway bars left alone. This gives me a little rear kick out on the exit of the turns. This is my set up. You need to play with the settings for your personal likes.

For mid corner understeer you can move the rear bar to a stiffer setting/position. The front bar change seems to have a bigger effect on the chassis balance than the rear, even though both bars change the wheel rate about 100lbs/in with each position move.

Rear bar is easier to change with the wheels off. I have used it a lot to reduce mid corner understeer and get the car to accelerate out neutrally.

I post more on the 500 fourm but this might help you.

I have the steeda dual rates & competition sway bars on a GT500 CFTP

I originally started with the rear bar on it's softest setting / front 3rd from firmest setting.

It originally felt good "learning" and getting some seat time. Car rotated pretty good, grip was good, but as I got more confidence and faster the car felt as it was heaving under hard braking and not settling between brake / turn in transition. So i stepped up the rear competition bar to full stiff. And left the front bar at it's setting. That did seem to help. (Been thinking to stiffen the front one hole) see how it behaves.

I did also just add a DSC controller to the car looking to further help the car get more settled and have better grip. I'll know Saturday how much of a change the DSC helps. On the street it already feels better flatter & more controlled.

Also camber settings here:
Had pretty even tread wear with the following.

Front -2.2
Rear -1.5

With my coilovers I am currently on a staggered setting on the front bar with one side on the 2nd stiffest setting and the other on the 3rd stiffest setting. On the rear bar i am full soft.

When I was on the DSC Magneride controller and the steeda dual rates I ran the front bar on 2nd stiffest front on both sides as the front rates were just too soft and this helped balance the car out a bit for me. With the softer rear I drove the car on the rear tires a lot more than I currently do and it worked decently well.
