I have created a 600pp (inspired to match Praiano's great 600pp offerings) Lambürgring tune for this car, tweaked it all week, still has some room for improvement, but it will take you around the Ring in less than 6:30 , top speed of 328km/hr. with no Aerofoil, and no Aids, no ABS. (and no mistakes) . I will post it here once I get home and turn on the PS3.
It has only Engine +1 Stock Weight (I like 1,500kg on the Nür), no rear adjustable wing (except for the fake painted one), 0 ABS Brake balance of 3/2 , mildly reduced heights, enough not to get kicked by the elevative changes, and doesnt understeer nor oversteer. the rear is stiffer than the front, due to it's natural weight distribution. Although made to drive as a pilot's car, it is not that unforgiving, due to it's design and weight. But for those itching to rediscover the car on the Nür with no aids,
I've tuned one from scratch, and am pretty happy with it, since it was my first in game purchased car when the game came out a year ago, which allowed me to win the faster races more quickly to unlock/progress through this game asap.
