Default Any way to correct understeer?

Is there some way to minimize Forester's rather heavy understeer? like changing wheels/tires or some suspension mods?

Is it possible to drift with stock forester? or will it flip over?

Default understeer

Imprezard...there are many ways to control understeeer. Sway bars/struts/springs/strut braces/tires.....there are also many opinions on how to best do it....stand by for those.

In the meantime , I'd recommend that you use the search function ...this is a topic that has a huge history and ongoing discussions/opinions on how to deal with our built in understeer.

Kind of like buying a new car.....which is best?....depends on who you ask.

Flip overs...I would guess you could make it happen....is it a real world issue?.....not that I'm aware of. The Forester is a very stable driver and rollovers are not an issue.

OK....my .02...I'm sure there will be more to follow

I would think that a 18mm rear bar would help the turn in. There is also a 20mm rear bar, but I'm thinking of a 18mm bar myself, the 20mm may be a bit much. If you want to make your Forester handle like a Miata be prepared to spend $$$. If it is even possible to. I think under the right conditions you can drift any car & roll any car. When I want to go drifting around corners I take my Miata out for a spin.

Imprezard,

If you want the Forester to handle like a monster (ie: drift) you will more than likely want the following suspension mods:

Impreza Struts: (KYB AGXs or FHI Ver.5s)
Springs: (Either Stock Subaru RS springs, or the 5Zigens or Tein Forester S-Tech Medium Springs)
Strut Bars: (Front and Rear. I like the Cuscos, myself, but any make shoud be about the same)
Rear Lower Bar: (Cusco or JC Sports make 'em. They help a little, and they are pretty inexpensive)
Rear Sway Bar: (The bigger the better for inducing oversteer. Try the 21mm for big slides [drift] , 18mm for nice controlled turns [no drift])
Wheels & Tires: (You will probably want to go with something either really low profile or with a really stiff sidewall to prevent tire squirm and sidewall fold-over. Maybe a 17"lightweight rim with 235/45-17 tires {this will throw off the speedo slightly, but will give you a little more bottom end, because of the final drive ratio change.})

Thats all for now. For explainations of most of this stuff, check out my website (www.foresterperformance.fanspace.com)

Best bang for your buck is probably to go with an 18mm rear sway bar. It helped quite a bit on my Forester. I can get the rear to kick out if I push it on slippery roads.

The easiest thing you can do for understeer is to alter the tire pressure settings between the front and rear tires. More pressure up front and less in the rears will reduce understeer.
