Cusco anybody..?? I prefer the RWD one, as I'm still relatively clueless regarding 4WD and diffs... {Cy}
4wds are easy - most common fault or problem is front tyre wear though.
Handling:
1) rear toe geoe negative
2) rear brakes go higher
3) Rear ride height lower than front - keep adjusting with 3mm increments (that's what I use -3 or -6 normally does the job).
LSD's:
Initial + Acceleration
Front = make outside tyre spin first
Rear = make inside tyre spin first
So something vaguely like:
Default=
10/10
40/40
change to:
20/10
24/12
Loosen the front a little, tighten up the rear (to compensate for the extra drive going to rear), then keep tweaking until required wheel spins first.
LSD Braking
Double front, half rear (defualt) i.e.
change from 20/20 to 40 / 10
Tyre wear:
Put as much drive to rear as possible, anywhere from around 30/70 to 10/90 split.
This is all subjective to power,weight, tyres and race distance. But once you get the hang of it it's pretty easy to tune 4WD's
This is just a very rough guide to get most / all 4wd's half decent, the variables are so great as 4wd cars vary so much in the game, it's hard to be specific.
A Veryon is very different to a Diahatsu shopping trolly with 4wd - same principle, but numerical settings might vary a wee bit.
Also tyres to, same car with comfort softs may need different numercial settings when fitted with racing softs - take each car individually but apply above principle generally to get easy, quick semi affective results.
Learn from tuning each car by the above generally, see what needs to be adjusted from each situation (track / tyres / power / race distance etc) - gain experience so when you have to tune a car for a specific situation you know what and how to adapt / change.
Make the use of ABC setup options for all round use on all types of tracks too.
