I'm thinking of picking up the Stillens during the sale on sunday. What did you end up setting it at Alchemy?

Id love to be able to tell you but I actually havent installed them yet. Gonna wait till spring since my Z goes off the road for winter. I will tell you this though, I will be setting it to the stiffest setting in the rear and softest setting in the front to help battle understeer. Im actually about to order the Stillen front lip from the sale right now:tup:

Suspension is one of my personal favorites when it comes to tuning vehicles. Whether it's offroad trucks, race cars, motorcycles (both street and dirt) I love fiddling with the suspension to make a vehicle handle better and go faster. Sway bars are a very important aspect of suspension tuning and handling.

You need to take a lot of things into consideration but the most important thing to consider is grip. If you have a lot of tire (meaning slick or something like an R888 or NT05) you can take advantage of a more aggressive bar. Also, if you have good traction (weather dependent) you will inherently have more grip in your tire which will also allow you to "run more bar."

At the end of the day, sway bars need to remain balanced. You might find that your front end is pushing too much so you give it more rear bar to compensate. What this does is actually prevent the car from rolling and actually force it to give up sooner. By forcing the rear of the car to give up you are allowing it to rotate through the turn. Now with that being said, you can go too far and cause the rear to give up too quickly...Again, it's all about finding the balance between front and rear.

We always recommend that people start with the middle setting. This will give you a good feeling of how the bars are going to work and from there you can make your adjustments. If you find the front end pushing too much, you have two options, set the bar back to the softest setting or put more rear into it. If you find the rear is too loose, you can put the front bar to the stiffest setting or drop the rear bar back to the softer setting.

Basically, with the STILLEN bars you have a lot of adjustability.

And yes, our bars are optimized for street and track cars, we do not make our bars for track only cars. With that being said, we still run our bars on our track cars. I am in the process of working with NISSAN on a project that you will see in the next few months and it will be built using off the shelf parts and it will be using our bars...This will be a track ONLY car.

I have the same feel as the OP. I installed the front first at mid setting and it was greaat, the car felt much better. Then went to the rear sway and installed it with soft and feels weird. Not just stiff but as is the camber arms are xhocked. at stock height and alignment is perfect. I have a friend who had the same feel and went to the middle setting and it got alot better. This is at the street and track. Ill try the same

the rear imo does not need extra stiffening on stock suspension.

no one said you HAD to replace both front and rear. just do the front for starts and use stock rear bar. :)

well my reasoning after being to the track with my tire set up and stock susp is that tad of understeer that I didnt mind on this track.... But I wanted to stiffen up the front and rear by the same proportion just to have less roll with the same balance. I spoke to stillen and the front at middle and the rear at soft should be the closest thing to what I want. Im gonna leave it like that and see what it feels like next track day. Dont take me wrong the car feels much much better I just wasnt expecting the rear to be this stiff when being at the softest setting.

sounds good. worst case, just use the stock rear bar. :)

If I may make a suggestion...take some tools with you to the track. Changing the sway bar end link mounting position is one of the easiest things to adjust while at the truck. Honestly, it's almost as easy as adjusting tire pressure. You don't need to pull the wheels off or anything.

Simply jack the car up, climb under and adjust the link. When you adjust the link, make sure you have both side of the car off the ground. Meaning, don't lift the left side, then the right. You need to have both tires off the ground.

Anyone have Stillen front/rear sways just for daily driving? And what setup did you use? Haven't ordered them yet, but leaning towards them as I've read Stillen Sways are the way to go for street driving. Probably going to start off with the middle settings front/rear, as what Stillen recommends. Just wondering if someone had a good setup already for daily driving. Any suggestions would help.

What ever happened with this?

I run both front and back at the stiffest setting. Everything seems fine to me.

I run Swift Springs on stock shocks, front Stillen at mid and rear at soft. Car feels excellent, I did have it aligned right after the springs. The only reason I got a rear bar is because of the stock shocks, otherwise I would have gone with stock or no rear bar. The car still feels like a stock car w factory setup.
