Can anyone explain how the differential lock works ?
I am playing with a setup for F1CS2K and need some advice.

Essentially, in simple terms, lock up is the amount the driving wheels
(rear in this case) are connected together.

100% lockup is as if the rear wheels are on one axel.  They turn at the same
rate.  This makes it very good for puttting down the power, as it's harder
to wheels spin.  But it makes it very hard to turn tight corners  (ie
hairpins and chicanes).

0% lockup is where the rear wheels aren't connected at all.  The outside
wheel could be stopped, and the inside wheel could spinning, and the car
wouldn't recieve any drive at all.  But it makes turning tighter turns much
easier.

Basically, you want it somewhere between these two.  Also, the higher the
lock, the more the rear end will loose grip as you turn as the inside wheel
fights the outside wheel.  It's only little, but it makes a big difference
at 180mph through Eau Rouge.

Tracks like Monza and Hockenhiem would run something like 80% lockup, where
somewhere like Silverstone or Spa would run less, maybe around 30%.

I'm guessing here, with general figures, not in game figures.

Hope the helps..

James

PS..  It gets more complicated in GPL, but essentially, that's the basics

Thanks

I wondered the same exact thing Gunnar, Also when you say higher lock
do you mean like 20:1 or like a 10:1? I always use "tighter lock" but what
do I know?.. :)
