I found this a while back and this is also very good..

To recap
race clean,
If you take the inside line hold the inside line
no sitting on the inside rear quarter of a car going into a corner (your front wheel inline with his rear wheel) side by side into a corner is side by side, not a partial overlap..
No divie bombing into corners.
no aggressive driving or retaliation, mistakes happen, 99%of the time it was a accident.
No reversing out on to the track after a crash .
ALWAY enter the track in a forward motion USE YOUR MIRRORS to check it clear behind you
Do not pull back onto the racing line until your up to race speed.
If you think you hit somebody you probably have, so maybe time to wait for them to get back on track before you start racing again. (If you run wide in a corner and leave no were for the driver on the outside to go and he goes off ) this is your fault you must wait for him to rejoin.
Different cars carry different speed through corners and brake at different point be aware of this.
study the car in front for a couple of corners before you pounce.
If your about to be lapped hold your line let the car behind make his move and then you can ease of the gas to assist him.. if you are the overtaking car pull up behind and pull out and drive around the car not through it. do not push the car you overtake around.
Do not look to take advantage over fellow racers whilst overtaking back markers,
they are also in there race so be nice and it will be returned.
The main thing to remember is we do this for fun, there are no trophies to win or prize money.
and should be driven in that spirit.
WE DO THIS FOR FUN
