Default Swaybar Advice? w/ new Ohlin Fixed-Perch Struts

Hi Guys,

It's getting to be time to replace struts, and I've decided to upgrade all around to the Ohlins fixed-perch setup. While I'm doing all that labor, I thought I should re-evaluate swaybars as well. I've decided to stick with the stock springs/tophats. I've got about 63k miles on the 04 STi, looking for streetability with occasional (5-6 times a year) autocross and ice racing. I'm not completely happy with the degree of understeer on the stock STi setup, so contemplating a stiffer rear swaybar.

Advice on brands and setup? Thanks.

Look also at the front sway. I know it goes against conventional thinking when it comes to sways, but a quick search here will reveal some interesting information.

As for the rear - given that you'll be rolling on stock springs I suggest a 22mm solid rear bar. That will equate to about a 23.5ish in the commone hollow bars out there.

I must also encourage you to replace your rear endlinks.

I just put on whiteline 27mm adj. front and 24mm adj. rear sways and they are godly. I have basically zero body roll now and my car just sticks. Oh yeah and i havent noticed any understeer. should also point out that Im on RCE springs.

He means the stockers will eventually break with the beefier sway so you should upgrade.

Most people seem to like kartboys.

Edit. qoute screwed up for some reason.

Just remember - you can still understeer if you go in too hot and exceed the lateral grip of your tires. I'm really good at this if you want a demonstration some time.

I have an idea to lessen this, but it's gonna take a g-meter to get actual measurement numbers. I've been thinking about this little guy:

Read everything that it does, and you'll see that for what you get it's not that bad. We really need to get one before the dragon meet so we can map the dragon and share it with others. I gotta look to see if that model does elevation or if I need to get one of the uprated ones for that.

If I had the money I would buy it (would be fun to play around with) but I'd rather finish upgrading my suspension first. Plus Im runnin real low on funds.

I'd be willing to pitch in. That's way too cool.

OMG! I soooo want to know what my car is doing on the Dragon! I never thought of using data aquisition like that. VERY good idea.

Mmm....Now I want to know how Porter car is doing on those roads....


PS Hope to see you there!

Yes you can!!! I will vouch for Clint being able to defy all odds and still be able to do this.

That's actually really cheap for what it does...BUT, I'd have a hard time autocrossing with my laptop in the passenger seat.
