    Auto x

    I'm relatively new to the Subaru world, but I've done some auto crossing before. I haven't taken my '09 WRX out this season and probably won't until next season. The reason being is because I run with the BMW club out of Chicago and I get stuck in the non-BMW group which means I go up against all of their weekend toys (Corvettes, Porsches, etc)

    I don't want to void my warranty, so I'm not looking to do anything to my engine right now. Can anyone tell me how much improved sway bars or any other suspension upgrades might improve my times.

    I know Tires are king in the Auto-X world, but the stock WRX tires are a lot fatter than most so I'm not looking to upgrade those just yet.

    bump.

    I know the purpose of sway bars. I'm just seeing if anyone has installed them and what kind of difference they make on a track or auto cross setting.

    Maybe I posted this in the wrong spot.

    I tried a Perrin 25mm front bar on its soft setting and HATED it. The car felt better on the street, but under autocross conditions, it understeered horrifically. I tested it against my stock sway bar and the stock was 0.6 seconds faster (on average) than the Perrin. Needless to say, I've got my stock front back on for the upcoming divisional event. If your class allows you to change your front and back bars, you might be able to find a combo that improves the overall handling of your car. Unfortunately, SCCA stock class rules only allow you to change your front.
