The softer front bar will give more understeer, as stiffening reduces net traction, leading to understeer.
I think you need to drink more coffee before posting.

The Saner is an auto-x bar. If you are tracking the car, most track people I know say that all auto-x bars are too stiff for track use.

I bought a modded Saner bar (a fourth hole was added to make it even stiffer still), but I run Penske DA's. To get anywhere near neutral or slight oversteer, I adjust the front rebound to about mid-range and the rear rebound to about 80-90% of full stiff.

I run AS auto-x though and have only tracked my car one time - it understeered way too much, but that was before I had the Penske's and have not tracked the car since.

It would also help to specify how your setup felt to you before you went with the Saner bar. If you're looking for something in the middle, there are a host of companies that make aftermarket front bars (Swift, Cusco, Tanabe, Mugen, etc.), but each bar is constructed differently ... those companies also make stiffer rear bars, too, and as was said earlier in a different way, you could try going with a host of different setups, depending on what you're looking for.

What you have right now is an auto-x bar ... do you auto-x a lot, or are you more into Thill and tracks like that?

I run a saner and do not have understeer, so does Krazik.

I'm not even running a rear swaybar.


It's all in the setup.

They would certainly know more about tracking a car with a Saner bar than I do. I was simply passing on comments about the Saner bar (and Gendron and Comptech bars) from people here in Phoenix that do track their S2000's

A stiffer front bar is better up to a point. The stock bar is stiff for a family car and really soft for a race car. But roll stiffness changes the proportional bias...and at some point starts reducing grip significantly.

"Increasing the proportion of roll stiffness at the front will increase the proportion of the total weight transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a higher slip angle, and the outer rear wheel to run at a lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer."

See http://www.gtplanet.net/forum/showthread.php?t=57625 for a detailed description about why most people who think stiffer is better are ...guests.
