what tips do you need exactly ?
general rules are:
1) get decent setups off setup grid or similar
2) get well set up with no force feedback but no deadspots removed.
3) set wheel to 720 max
4) practice doing 180's and weight transfer ( heavy turn left, feed to the right and vice versa )
5) nail the basis then give it a week or two and you'll be driftin like a boss
6) buy s2, drifiting is generally better on here... same amount of kids moaning all the time but theirs one or two cool people who'll share more personalized sets ( i'e other dfgt users )
7) some people use slightly different tweaks and setups, response rates etc... its more of a live and learn thing for me and my DFGT... but hey, thats half the fun ! again, if you ask politely most should help you no problem, if not, avoid them and their server, they're not worth you're precious time.
if you need any more advanced advice just ask, ive been usin my DFGT about 2 years i'd guess and after buying a g27.... i think ill keep the g27 pedals and use the dDF wheel
