Hi,

at first:
Sorry, my english isn´t the best...


I just want to say, that i don´t like the locked diffs on hard track.
In rL you can´t drive a locked diff (and espacially not with downforce and slicks!)
Because you grip is so high, that something will break. e.g. the axle...

On autocross (Real autocross, not the autocross track in LfS) is it possible to drive a locked diff, because u have so much slippage that there will nothing happens.

What do u think?

There have been numerous discussions about this before. See here:

lotus ran the lotus 78 f1 "wing" car in 1977 with a locked diff to counter the rather large amount of front end grip. ironically when they transplanted the nose spec to the lotus 79 "ground effect" car in 78 they found they couldn't get enought front end grip.

porsche ran their endurance racers with locked diffs a lot of the time in the 70's, especially the 935 as the last thing they wanted was the rear sliding on it.

so yes you can run a locked diff in real life with slicks and downforce but you either need a very good front end or require understeer. (both of these examples were rwd of course, i can't think of a single fwd car thats run a locked diff on tarmacthough i'm sure someone can think of one, though i know a few mini's ran very high settings on their diffs, even on tarmac

Oh,

thats really new for me, that it´s possible to drive a locked diff.
But can it be, that the tyres weren´t the best in this years? So they had more slip to compensate this big forces?

I heard, that it´s not possible to drive a fwd with locked diff, because the steering forces r so big, thats really hard to drive it...

what you have to remember is that the examples i gave were used on race tracks where there were no tight corners, no way lotus used the locked diff at monaco, the push would just put them straight into the barriers on the tight bends

i'd hate to think of the forces involved with a fwd with a locked diff, even a fairly mild lsd can give some nasty pulls on the steering wheel though power steering obviously helps

there are quite a few clubbie racers that use locked diffs it works but yeah, the steering forces can be unbearable. the only reason locked diffs are so popular in LFS is due to the fact that we don't have decent LSDs yet, and we don't have to deal with hurrendous steering forces.

when we eventually get a properly modeled plate-diff we'll see a lot more people using them.

Racing is also different than real life: tires only have to last a matter of minutes or hours, not months. There are people in real life that run locked diffs daily, but at the expense of changing tires more often. In a game where you can just have the tires changed when you pit, its not as big a deal.
