What league NIKI suggest´s but isnt posting a link is: http://www.lfs-league.com/
the season is more than half way through but i think u still can signup and do the racing with the guys.
The x-drifter i am i was on 720-900 on my old G25 with axclutch+h-pattern.
And since i´ve bought T500rs that has 1080 "not sure of it 100%sync with lfs on that value tho" but i still tend to use 720/900/450 depending of car and class.
if the server is using a !top list aka lapper "guess u know what lapper is tho " annyway: if it uses this and are coded/cfg´d that way it counts points for drifting - lets say angle, speed, linkin corners etc..
with a NOS u could get mutch more speed and gain maby 1/3of the total point just @ entry. TVE is/are correct tho.. NOS aint helping mutch when it comes to drifting.
