I had some kind of amazing results at an auto-x today...



Anyone who drive's Subaru's hard learns that they want to pickup the inside rear wheel on corners. My car has been doing it excessively for the last year.
I've been running RaceComp front and rear swaybars with the front set on full and the rear set on the middle. As the car continued picking up the inside rear tire on corners, I dialed the RSB back to the lightest setting.

At the advice of Mr Sam Strano, I removed the RCE rear bar and installed a 17mm bar off a Forrester. You know what... wheel lift is gone. This wasn't unexpected, but usually when dialing back a rear sway bar one expects a car to get more pushy... only mine didn't. I ran a little more tire pressure out back and the car behaved perfectly.
No more understeer than before, and the car STUCK on corner exits.

Totally counter intuitive, but somehow works.

 

HMMMMM really. I know someone here has put the 13mm legacy postal FSB on their bugeye to get more front end dip but doing the reverse in the rear?! That's a huge surprise.

 

I am running the 25mm cobb front and rear, with the rear set to its highest setting. Theonly time I "lift" the rear, is when I come down a driveway/ramp at an angle and I end up lifting the tire off the ground.

I iwll have to pay attention to things this next season and see how the FXT deals with the corners.

 

I love rear inside lift. LSD makes the outside rear get more power and I get great follow through, on gas, out of the corner. Sometimes I get the tires to chirp, but its rare.

 

My experience is that when the inside rear sets back down it completely upsets the car.
I have an 04 with a Torsen style rear diff. Torsen's don't work when one of the wheels has zero traction. If you're running a Clutch Style LSD, the problem probably won't be as nasty.
BUT in general picking up a rear wheel really isn't a great way to have a consistent car

 

Which rear diff are you running? I've never had rear lift even with your old 27mm bar...

 

Isn't that a good way to snap an axle or strip out the splines? I know that in the 4x4 if you don't come off the throttle when you lift a tire, you will *SNAP* break a part someplace.

 

You lift your rear?

 

Heedz, is it possible for you to go a day without being a troll?

 

Nobody likes the Tuna already.

 

If you come down with the wheel spinning, sure. But like Gagan said,

It's rare. Even with my open diff, it doesn't happen often. I usually lift a wheel on a really tight corner where I am off the throttle. When I'm out of the turn and ready to get back on the throttle, the wheel as already come back down by then.

 

Sam Strano seems to know his stuff. I run his front sway bar on the BRZ. It makes sense though. You're tying both sides together, so whatever one side does the sway bar will try to make the other side do the same. So when you made the turn, the outside rear compresses and the sway bar causes the inside rear to compress as well.

 

I like the tuna here.

 

I thought you didn't like fishy smelling things.

 

If you have a torsen then I'd go smallest RSB possible or no sway bar and tune it with high spring rates if you got good enough shocks, because yeah, lifting the rear on your car will basically cut power.

I have a clutch type. Ummm, no, its not really upsetting. Considering I'm on the gas through most of the turn, I don't lift through most of the turn. I get some lift when I lift off the gas pedal, but it comes back down soon as any gas is applied. Sometimes I can get some wheelspin before that weight transfer finishes but its rare.

Whether the wheel is up, off gas or down, on gas: I like it.
