"corecting" understeer, if you can even call it that, is the easiest thing in the world to do.

you lift

thats why almost every sedan today is designed to understeer. its a crap load safer then oversteer.

by lift i assume u mean lift ur foot off the throttle to transfer weight to steering wheels... that will help with mild understeer but hairpins and such it wont do squat

Exactly. Theres a crapload of understeer dialed into a stock WRX chassis on purpose, that much is clear. I believe the reason is to keep noobs alive.

I have the cusco front and rear ARB's. I used to have the perrins, but the design of their bar puts more directs more of the energy into the mounting points, instead of acoss the entire bar. In my opinion, Japanese car, Japanese parts. just makes sense to me. Start coming out to the track and hook up with an instructor and go from there.

I don’t really see how the type of turn is relevant. But you are correct, lifting off the throttle will only remedy light to moderate understeer. But conversely, if you have what I like to call epic understeer, one of two things is occurring; a) you have no idea how the hell to drive your car, or b) your setup it incredibly off.

The thing that sux about understeer as aposed to oversteer is there is no way to fix a lot of it. If you have a lot of oversteer you just toss the wheel to the rack and apply appropriate throttle. Understeer on the other hand has only one true plausible solution, lift. The objective of corse is to get back within the limitations of your tires ability to provide traction. Accelerating or turning the wheel more do absolutely nothing to tires that don’t have traction.

well if you're flying through a not so sharp turn and need to gain a bit more front traction then easing off the throttle would help. versus a hairpin its too sharp for that to matter if your flying through.

i think physics are relevant..

There was a really good thread about this on nasioc (believe it or not), and a couple guys there really know their suspension stuff and explained everything through physics. I'll try to find the thread.

Uhh... from what I know, oversteer is a lot harder to correct. For example, if you're in a MR2 (a car that can obviously oversteer), and you go into a turn too fast and break the rear loose, if you brake you take weight off the rear which causes more oversteer, and if you gas most of the time add too much extra power which causes less traction also.

While understeer, you can gas while braking (left foot breaking) to ease understeer. That's why a good ITR can be one of the fastest cars around an auto-X course, instead of a 240sx or MR2.

Correct me if I'm wrong, but that's my look on it. Of course my MR2 owning friends always tell me oversteer > understeer for daily driving...

You are correct, understeer is a lot easier to correct then oversteer, thats why most cars understeer from the factory as stated above.

When you learn to drive a RWD car good, you learn to steer with the throttle. On cars like the S2000, it is a great handling car but totally unforgiving if you kick the rear out and don't know what to do.

On AWD and FWD, a larger rear sway bar definitely helps, it will also make lift throttle oversteer a lot more pronounced.

you forgot choice c) road conditions. up/down hills, rain, snow, leaves, manuevering around deers, etc...

the only way i've found to keep understeer from every happening is just oversteer instead. lol

edit - i've never seen so many people talk about something they really dont know about. guess thats just part of the being on an online forum.. just like a part of that is how bad im gonna get flamed

Humm... I was talking to sam strano and going to order one of his 32mm front swaybars to help my understeer problems. That at sticky tires some v710's. I am a noobie on the sti thing. I have had mine for 4 months and going to autox it more then I did with my z28. I did one autoX last season and it pushed alot. I still was getting used to driving it. So I was talking with Sam he said I should upgrade my front and leave the rear stock. Hell I am going to try that and will report back my findings.
