The oversteer on power issue in FWD cars is there with practically any setup (I haven't tried one that doesn't have it from default onwards ), my belief is it is a tyre phusics issue not a setup issue
All fast setups have it because it's better. The issue might originate from some small physics bug, but it's the ability to setup the car so much makes it easy to take advantage of the bug.
Oversteer in FWD on power? I've yet to see this. I got send a setup that supposedly did this, and found plenty of understeer off the throttle, and yes, less understeer under power. But oversteer? No way. Barely neutral.
Perhaps Colcob will analyse slip angles and prove this.
You don't like FWD's so you probably haven't driven them enough to find how
It is more a technique, than anything else, to get the most of this effect... when powering out of a corner in a FWD at the same time gradually straighten the wheels (even if you need more turn angle) and you will find that the car will turn better
In other words if you find yourself understeering on power out of a corner simply straighten your wheels slighty and the understeer will disapear
You can get any car's arse to slide out of a corner. I've been doing some research on this for a project I'm working on. Here are the equations for slip angles:
Delta (that reversed 6-like thing) is the steering angle of the wheel and sgn(x) = -1 for x < 0, sgn(x) = 0 for x = 0 and sgn(x) = 1 for x > 1. Omega (that w-esque thing) is angular velocity and b and c are the Forward distance between the Center of Gravity of the car and the wheel (ie. only on the Y axis) like so:
If the slip angles at the back are greater than those at the front, you will get oversteer. I'd say it is a corner entry techniqe where you have quite a low brake balance (ie. more brakes on the rear) and the car enters a corner with slight oversteer. Then using differential settings, you can keep the slight slide maintained for a while using differential settings. You will however find that the sideslip angle of the car:
Not really sure what you are trying to tell us axus but the effect I'm talking about is in the last phase of the corner and I also use it to tuck the nose in just before the apex (i.e. apply a little throttle to reduce understeer). I don't get any sliding of the rear that I'm aware of, but the GTi often has the inside rear wheel off the ground just before the appex and mid corner .
