hmm i guess i didnt explain that well enough. i didnt mean front engine handle better because of setup. what i meant to say is that just because a car has its engine in the front does not mean it has to understeer or has to oversteer. nomatter where the engine is, with a little adjustment you can have pretty much any car push like crazy or oversteer like crazy. so engine placement doesnt have to mean that the car is going to handle a certain way.
the difference between front and mid/rear engine cars is more in how much grip is possible and how they handle at and past the limit.
and in alot of cases, probably more often than not, fast in can mean fast out. with a neutral setup car(which is usually what you want) a fast entry to a slow corner usually means that the car will rotate more, allowing it to get pointed at the apex better and quicker, allowing you to get back to power sooner. where with a slow entry the car would be either neutral or maybe have a little push, making it wide of the apex or harder to get there, meaning you would have to wait longer to get back to power.
and with high speed corners, high speed entry can result in a faster exit. its hard to pick one specific example, but it makes sense in the case of momentum, if you slow alot for a fast corner, even if you get to power sooner, the car has to work harder to get back up to speed. carrying momentum through the entrance and mid corner can result in a fast exit too. and in the case of stability, a car may be more stable in a high speed corner while under power. say if you do a full lift in a very fast corner, and get to power at the apex, the car may be more unstable, making the whole corner slower including the exit. where if you did maybe a longer lift, but only to 1/2throttle, or start your lift earlier. the car could be more stable because the car is under some power rather than slowing. or just the fact that the car is still under power may mean you can lift less because the car is more stable, and can take the corner faster.
there are some cases where a corner will be easier to take flat out rather than with a big lift because the rear will be so much more planted.
obviously, fast in doesn't always mean fast out. but more often than not it does.
