thanks for all the input.
i iam running
40w shock oil all round with 3hole pistons and 1.5mm droop at front and 2mm at rear.
iam racing mod 12t limit.
after checking the rear diff i cured the understeer.
the rear diff came loose but still transmitting power making the car understeer going into through and out of corners.
ive replaced worn parts such as balls,plates,nuts and the bolt and tightened up and with my settings the car was so nice.
i qualified 3rd and finished 2nd in the a main and set a new track record.
only 2nd time run car on ashphelt as i normally race on carpet and it rocks!
cant wait for evo4
