Let's say there's a long high speed sweeping corner that's shaped like a "C". It's long/gradual enough that you can accelerate through it the whole time. So let's say you're in 3rd gear, and then you have to upshift to 4th gear. Wouldn't this induce oversteer, since it is lifting off? What should you do? Do you just not upshift?

Also as a side note, does it seem like lift off oversteer is non existant in GT5?

Sorry if it's in the wrong section.
 
If the corner is open enough that you're able to accelerate through it and require an up-change in the first place, it's unlikely the car you're driving is going to be loaded up enough that changing gear would upset its balance and cause lift-off oversteer.

If you were in a constant radius or tightening radius corner with the tyres fully loaded and then you lifted off, you're much more likely to experience it.

Even then, it depends on the car. Some are naturally stable enough that you'd simply tighten your line, and if the corner really did tighten quicker than expected you'd still be more likely to understeer off than oversteer. Braking might induce oversteer but it really does depend on so many factors.
 
Off throttle oversteer is caused by upsetting the balance of the car. You can do the same thing if you slam down a gear or two without matching revs -or- giving the steering wheel a quick flick.

In most cars, the understeer that's present will prevent the scenario described in the OP. Secondly, when the clutch is in there isn't really any weight transfer going on. If you're engine braking, then you might get some rotation. But taking a fast corner while disengaging the clutch isn't going to do much else than coast like you would normally do if you're driving a car w/an autobox and take your foot off the gas pedal.
 
Yeah, everyone here sounds about right, particularly BS - as long as its not an abrupt lift of the throttle and a moment before stabbing the clutch, it would probably be fine. If you didn't match the revs on the upshift (let the revs fall to idle or something) and then engaged the clutch, that might upset the car a little. The other issue would be if it was a hard upshift and the car had enough torque that it actually broke the rear end loose a little, but, that's not lift-off oversteer, just power-oversteer that could be of the snap- variety also.


Would probably have to be an early Porsche to have any issues with this corner.


In GT5, it doesn't seem as bad as in GT4. But MR cars and RR cars are still less stable and usually benefit from some throttle application through corners to keep the rear planted.
