handling line help perfect jester

[papermun]

hi i wish to make a perfect jester handling line or at least 1 that is good.i want to go above 330km/h without problems.

so i hope you guys can help me out

i only know how to tune the max velocity and acceleration and some other misselaneous

the current problems tat i encountered is when i start driving it will have skid marks and i will be very slippery before i gain a bit more speed at it will stop skidding.

and the other problem is when i am at higher speed i try to move to avoid traffics at the highway the steering will be less active as in it feels stuck.

and when i try to steer at high speed it will skid and its hard to control it.

i hope you guys can tell me what to increase and what to decrease.

many thanks,

papermun
